Here are today's MLB games, ordered by watchability, based on how interesting the teams and starting pitchers look. Higher is better. For more information, read this post.

Notes:

• Pitcher 'no data': Pitchers only have a pNERD score once they've started at least one game and have at least 20 innings pitched. I also show 'no data' when I can't correctly link a starting pitcher with their stats.

Miami Marlins @ San Diego Padres, 5:40p

Summary

San Diego's playoff push meets Miami's lame-duck reality, and the Padres bring by far the juicier storyline here. With a gNERD of 15.56 — comfortably above the historical 95th percentile and near the top of today's slate — this one's worth your remote.

San Diego enters riding a hot stretch that has them pushed to 85-69 on the season and pulled into a three-way tie for the wild card spots in the National League, while Miami has already been eliminated from the postseason race, so only one dugout has anything at stake. Making matters worse for the Marlins, their bullpen is a genuine wreck — Andrew Nardi, Anthony Bender, Pete Fairbanks, and William Kempner are all unavailable. On the mound, Eury Pérez is the real draw: 23 years old, sitting 98 mph, and posting the best pNERD of the night (7.14) thanks to elite velocity and whiff rates. Casey Mize is comparatively unspectacular (pNERD 4.19), a fine innings-eater rather than a show-stealer. San Diego's tNERD (10.72) leans heavily on a dominant bullpen and top-shelf fielding — the engine behind their surge — making this a legitimately watchable pairing of contender urgency and individual pitching intrigue.

San Francisco Giants @ Los Angeles Dodgers, 6:10p

Summary

Tarik Skubal doing Tarik Skubal things is reason enough to tune in, even if the Giants' half of this game is a mystery. The Dodgers grabbed Skubal at the deadline in a blockbuster that cost them serious prospect capital, and he's rewarded them with exactly the swing-and-miss dominance you'd expect from a two-time Cy Young winner — his 11.96 pNERD sits near the top of the scale we track, and this outing marks his final regular season start at Dodger Stadium this season, pitching on four days' rest for just the second time this month. San Francisco's counterpart is a total TBD, contributing nothing to the pitching math and adding a bit of intrigue by omission. The Dodgers' lineup (8.52 tNERD) dwarfs the Giants' punchless 3.52, backed by real batting and bullpen strength, while San Francisco limps in as a team whose 64-89 record makes late-September relevance mostly theoretical. At 14.50, the gNERD clears both the historical 95th percentile (15.60) and today's average handily — mostly on Skubal's arm alone, so watch for the strikeouts and stick around only if the Giants can make it interesting.

New York Yankees @ Arizona Diamondbacks, 5:10p

Summary

A potential Cy Young front-runner takes the mound in the desert, and even without Aaron Judge in the lineup, this one's worth your attention. Cam Schlittler comes in carrying a 1.95 ERA and 228 strikeouts, and just passed Whitey Ford, Ron Guidry, and Jack Chesbro for the most starts with 1 run or less allowed in Yankees history — his pNERD of 10.96, built on elite xFIP-, 98-mph heat, and a hefty swinging-strike rate, is comfortably above today's average and near the historic 95th percentile. The bad news for New York: the Yankees are expected to place Judge on the 10-day injured list Saturday due to a right calf strain, though the lineup still has Bellinger, Rice and Volpe to lean on. Brandon Pfaadt is the far less flashy pitching story, a league-average arm (pNERD 4.11) with a 3.77 ERA and 84 strikeouts giving Arizona a chance to hang around. Team-wise the Yankees' tNERD (7.46) outpaces Arizona's (5.58), fueled by New York's barrel rate, while Arizona's speed and defense keep it from being a mismatch — Corbin Carroll and Geraldo Perdomo's stolen-base game remains a weapon even when the offense stalls. The 14.06 gNERD lands well above both the historic and today's averages, making this a solid watch.

Milwaukee Brewers @ Baltimore Orioles, 1:05p

Summary

The Brewers roll into Baltimore boasting the best record in baseball, and even in a lower-stakes September getaway game, this one has more going for it than most Saturday matinees. Milwaukee's lineup and bullpen numbers are legitimately strong across the board, giving them the best team score of anyone on the slate today, while the Orioles, playing out a lost season, still bring enough contact-quality and pop off the bat to keep things from getting boring.

On the mound, Robert Gasser (4-5, 4.30 ERA, 4.32 FIP) is still auditioning for a spot in Milwaukee's rotation come postseason time, and he'll be making his first career appearance against Baltimore. Trevor Rogers is the more interesting arm here — his 4.22 season ERA hides that he's been pitching to a 3.03 SIERA over the last month, with his K-BB% climbing to 24.5% since the All-Star break, exactly the kind of positive-luck arrow pointing toward continued quality starts. Throw in a bit of roster trivia — Brewers infielder Joey Ortiz debuted with Baltimore before being flipped to Milwaukee — and this game clears the historic average comfortably, even if it won't dethrone today's marquee matchups.

Detroit Tigers @ Chicago White Sox, 11:10a

Summary

Detroit and Chicago are both playing out the string, but this one has a bit of juice thanks to a pitching matchup trending upward and a White Sox club chasing Cleveland in the AL Central. Jobe, Detroit's 24-year-old former third-overall pick, is fresh off his strongest outing of the season, allowing one run on three hits over a career-high 6 1/3 innings against Colorado while striking out a career-best eight — a nice rebound after Chicago torched him for six runs back in August. His velocity (97.1 mph) and youth both grade out well, pushing his pNERD to 6.66, comfortably above average. Burke isn't far behind at 5.70, backed by a strong strikeout rate and a tidy xFIP-. Team-wise, the White Sox's 8.03 tNERD stands out — a young, cheap roster that's outperforming its payroll — while Detroit's 3.59 is dragged down by shaky baserunning and fielding. With a gNERD of 11.99, this sits a bit above the historical average and today's slate average, making it a reasonably solid, if unspectacular, watch for a Saturday between two teams playing out very different kinds of seasons.

Philadelphia Phillies @ New York Mets, 1:10p

Summary

A playoff-hungry Phillies club visits a Mets team that's already packing it in for winter, but the pitching matchup has more zip than the standings suggest. Philadelphia is tied with the Cubs and Padres for the NL wild-card spots and desperately needing wins, while New York is already eliminated from contention and 15 games back — playing out the string under interim manager Andy Green with a -43 run differential. Andrew Painter, the 23-year-old former top prospect making his rookie season debut, carries a pNERD of 7.34 fueled by mid-90s velocity and youth — his 5.54 ERA masks better underlying stuff, with a big positive luck score suggesting he's due for better results than his record shows. Christian Scott counters with a tidier profile (5.92 pNERD, 94 xFIP-) and has quietly been the better arm this year. Team NERDs are close and unspectacular — Mets nudge ahead on barrel rate and broadcast appeal, Phillies lean on bullpen and baserunning. The 11.73 gNERD clears both the historic and today's averages, making this a solid, if unglamorous, watch anchored by two young arms worth tracking.

Washington Nationals @ St. Louis Cardinals, 4:15p

Summary

Two also-rans playing out the string, but a sneaky-good pNERD from a lefty who no-hit the Angels for seven should keep your attention. Both Washington and St. Louis are buried in fourth place with nothing but pride on the line, yet the gNERD of 11.48 clears the historical average and lands right around today's typical game, mostly on the strength of the Nationals' surprisingly lively tNERD of 8.36 — built on elite baserunning and a young, cheap roster, even though a shaky bullpen (Bullpen Runs of -30.3) drags it down. Cardinals counter with a middling 5.70 tNERD, propped up by youth and payroll but dinged by a lineup that's been quietly punchless all year. On the mound, Alvarez comes into the game 2-6 with a 3.35 ERA and was great in his last start, giving up no runs on just one hit in seven innings against the Angels. His xFIP- of 90 backs that up as more than a one-off. McGreevy, meanwhile, is 7-9 with a 3.83 ERA and pitched well in his last start, allowing just one run on three hits in six innings against the White Sox, though his modest whiff and strike rates keep his pNERD at a pedestrian 3.67. Washington already won the series opener 9-1, evening the season series at two apiece, and the Cardinals have lost three straight to fall to fourth in the NL Central. Not a marquee matchup, but Alvarez alone makes it worth a look.

Kansas City Royals @ Pittsburgh Pirates, 3:40p

Summary

Both of Cameron and Chandler are well documented in search results, plus Bobby Witt Jr. and Konnor Griffin storylines. Now writing the summary.

A middling gNERD score dressed up by two live young arms worth watching, even if the standings say otherwise. Kansas City's playoff hopes are long dead (67-87, buried in the AL Central) and Pittsburgh is treading water at .500, but this one's really about the pitchers. Noah Cameron has been quietly one of the better second-half starters in the league, the season line undersells him — since the All-Star break he has posted a 2.42 ERA and a 0.88 WHIP over roughly 70 innings, and his NERD components reward his low walk rate and youth even if his velocity is unremarkable. Across the mound, 23-year-old Bubba Chandler brings a wholly different profile: he's still just a rookie building his track record after debuting on August 22, 2025, becoming the first Pirates pitcher to record a save in his MLB debut, and his NERD score leans almost entirely on triple-digit heat rather than command, with a walk rate to match. Pittsburgh's tNERD edges Kansas City's thanks to a bullpen that's actually performing while the Royals' pen has been dreadful, though a positive Royals luck score suggests Kansas City's offense has underperformed and could be an out-away from breaking out. Not essential, but not empty calories either.

Boston Red Sox @ Tampa Bay Rays, 1:10p

Summary

A tidy little Saturday tilt between two teams still playing meaningful September baseball, even if the arms on the mound are more solid than spectacular. The Rays are on the verge of their first AL East title since 2021, riding a dominant 53-26 home record, while the Red Sox are scrapping for a wild card spot and have been red-hot since July. Bello brings a 5.31 pNERD built on a tidy 95-mph fastball and a deceptively deliberate pace, though his well-documented struggle with left-handed power (1.46 HR/9 to lefties versus 0.38 to righties) makes him a live-wire against Tampa's lineup. Peralta, meanwhile, has been quietly excellent since escaping a rough Mets stint, posting a 3.86 ERA with Tampa and an even sharper 0.78 ERA over his last four outings, including a five-inning hitless effort — though his 4.03 pNERD reflects so-so strikeout command underneath the shiny recent results. Boston's bullpen (one of the league's best by runs saved) and a Rays offense that gets on base without much thump (rock-bottom barrel rate) round out a game that lands almost exactly at today's average gNERD of 10.46 — competent, competitive, but not must-see.

Chicago Cubs @ Cincinnati Reds, 3:40p

Summary

Cubs are chasing a Wild Card spot, holding their own against a fading Reds club, and the pitching matchup pairs a steady veteran against a struggling sophomore—entertaining mostly because of what's at stake, not because the arms are must-see.

Chicago sits 11 games back in the NL Central with Milwaukee having already clinched the division, so the Wild Card is the only path to October, and the Cubs are currently tied with the Phillies for a Wild Card position, holding the tiebreaker. That urgency helps offset a middling gNERD of 10.46, just below the historic average of 10.81. The Cubs' 10.35 tNERD is elite—built on top-shelf batting runs and fielding—while Chicago has hit a league-leading 211 home runs and scores the most runs in baseball at 5.3 per game. The Reds, by contrast, are limping toward the finish; Chicago has dominated the season series going 7-3, and the Reds have gone 3-7 over their last ten games. On the mound, Boyd's pNERD of 4.17 reflects a durable, strike-throwing veteran, while Lodolo's season "never even got on the rails to start with," and his 1.79 pNERD, dragged down by a rough xFIP-, confirms it. Worth a look for the stakes, not the stuff.

Toronto Blue Jays @ Texas Rangers, 4:05p

Summary

The wild-card math makes this one matter even if the underlying metrics don't scream must-watch: Toronto and Texas enter tied at two games back of Cleveland for the final AL playoff spot, so every out here carries September stakes. That urgency papers over a gNERD of 9.42, comfortably below both the historical average (10.81) and today's slate average (10.76). Texas has the sharper form, having won five of six, including Friday's 7-1 rout in which Dylan Cease walked six and lasted only 2 2/3 innings — not tonight's starter, but a reminder Toronto's rotation has been shaky. José Soriano gives the Jays a real weapon, though: his 6.89 pNERD is built on 96.7 mph heat and a tidy 91 xFIP-, both well above average. Cal Quantrill, by contrast, checks in at a modest 2.65, with a middling xFIP- and unremarkable swinging-strike rate. Toronto's offense (barrel rate near the bottom of the league) is the weak link on the tNERD side, while Texas's bats have quietly outproduced expectations, sporting a strong positive luck score that suggests more slugging may be coming. Watch for Soriano's stuff more than the scoreboard drama.

Minnesota Twins @ Los Angeles Angels, 6:38p

Summary

Both teams are out of the playoff race, but this one has a genuine reason to tune in: Reid Detmers. The lefty has strung together seven straight quality starts, allowing just six runs total over that stretch while striking out eight and walking only one in his last outing against Seattle, and his 2.45 xFIP component is the best pitching-related mark in this matchup. Joe Ryan isn't far behind, pairing strong strike-throwing with a tidy xFIP- of 89, giving this game two pitchers actually worth watching for their stuff rather than their win-loss records. The gNERD score of 9.01 sits a bit below the historical average (10.81) and today's slate average (10.76), dragged down almost entirely by the offenses — Minnesota's tNERD of 3.03 and a paltry 0.74 for the Angels reflect two lineups that just don't do much of anything well, with both teams posting negative baserunning and fielding marks. The Twins are also missing Byron Buxton (hip) and Trevor Larnach (wrist), thinning out an already middling attack. So: skip it for the bats, stick around for the arms, particularly if you want to see whether Detmers can make it eight scoreless-ish outings in a row.

Atlanta Braves @ Houston Astros, 4:10p

Summary

A middle-of-the-pack watchability score, elevated mostly by playoff stakes rather than must-see stuff. The Braves have already clinched a postseason berth while the Astros are still scrapping for the AL West crown, so Houston brings real urgency even if Atlanta is just playing out the string with one eye on October.

Grant Holmes (pNERD 3.40) brings good strikeout stuff but a homer problem—he's allowed 20 home runs in 141.2 innings, which matters against a lineup featuring Yordan Alvarez. Hayden Wesneski (pNERD 4.01) is the more interesting story: he returned to the rotation in late July following Tommy John surgery, and his last three outings have been erratic—dominant one start, shaky the next. Both arms are being handled carefully down the stretch, so don't expect deep into games from either.

On the team side, Atlanta's tNERD (5.19) outpaces Houston's (2.66), with the Braves' strong bullpen and barrel rate offsetting shaky baserunning; Atlanta is also running notably unlucky, which nudges expectations upward. The Astros counter with solid raw offense but weak baserunning and fielding. A serviceable but unspectacular watch, elevated mainly by the Astros' division race stakes.

Athletics @ Cleveland Guardians, 3:10p

Summary

Cleveland's stuck in a pennant fight, Oakland's just playing out the string, and the pitching matchup is fine but unspectacular—this is a watchable-if-nothing-better-is-on kind of game. The Guardians sit atop the AL Central, and every game from here carries real weight, while the A's are closing the final road trip of its 2026 regular season with four straight losses banked. Cleveland's tNERD of 6.90 is respectable, built on a young, cheap roster (age and payroll both score well) and a strong bullpen, though the offense is thin—Cleveland has scored 636 runs with 149 home runs this season, both near the bottom of the league. Oakland's tNERD (2.32) reflects a rough year across the board, with injuries not helping—Tyler Soderstrom is on the 60-day IL with a hip injury, which puts more pressure on Lawrence Butler to carry the offensive load. On the mound, Tanner Bibee (pNERD 2.70) is the better arm here, last pitching September 13 at Minnesota, striking out seven over 6.2 innings in a Guardians win. Jacob Lopez (pNERD 0.53) offers little statistical intrigue. With a gNERD of 6.22, well below the historical average of 10.81 and today's field average of 10.76, this one's mostly for Cleveland completists tracking the standings.

Seattle Mariners @ Colorado Rockies, 5:10p

Summary

This one is for completionists only: a last-place snoozer between a Mariners team playing out the string and a Rockies club stuck in a 56-98 nosedive that includes a nine-of-ten-games losing stretch. The 4.21 gNERD lands near the bottom of today's slate (which ranges up to 15.56) and well below the historical average of 10.81, so temper expectations accordingly. Bryce Miller is the one bright spot, his 6.41 pNERD driven by a 4-9 record with a 4.19 ERA that undersells a fastball that still sits at 95.9 mph and a strong strike-throwing profile — though his molasses-slow pace drags the number down. Jose Quintana, at 37, offers the opposite: a -2.39 pNERD anchored by an ugly 140 xFIP- and diminished velocity, suggesting the Rockies' lineup should feast if they can stay awake. Speaking of feasting, Hunter Goodman has slugged 38 home runs and scored 80 runs for Colorado, one of the few individual bright spots on a team otherwise near the bottom of the league in batting and fielding runs. Both clubs carry modest positive luck, meaning things could get worse before they get better — not exactly a selling point.
