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.

Chicago White Sox @ Chicago Cubs, 5:05p

Summary

A crosstown rivalry game that actually backs up the hype with two of the day's better team NERD scores. This one sits well above both the historic and today's averages, with the Cubs' 9.70 tNERD anchored by elite team defense and the White Sox punching above their modest payroll thanks to a young, athletic roster.

The Cubs bring MLB's second-best defensive efficiency and fielding runs that rank near the top of the historic distribution, while the White Sox counter with sneaky pop — third in the AL with 164 total home runs, averaging 1.3 per game. It's a Wrigley Field renewal of the crosstown rivalry, with the White Sox riding a 2-game winning streak in the series after taking the last meeting in May. On the mound, Imanaga has been quietly effective (6.04 pNERD, comfortably above average) thanks to excellent whiff and strike rates, though scouts note he's a fly-ball lefty with a 36% ground-ball rate and a 1.8 HR/9 mark — a dangerous combination if the wind cooperates at Wrigley. Castillo, a midseason trade arrival, brings solid stuff (95 mph average velocity) but has been old-fashioned bad-lucky, with a 24.0 luck figure suggesting his results should improve. Between the defense, the power bats, and two capable arms, this is one of the day's most watchable matchups.

San Diego Padres @ New York Mets, 4:10p

Summary

This one's about swing-and-miss stuff versus survival mode, and the gap between the two starters is the whole story. Nolan McLean, the Mets' 24-year-old sophomore righty, brings a 8.50 pNERD built on excellent xFIP-, plate-friendly pace, and youthful helium; he's coming off his 25th start of the season after throwing six innings against the Atlanta Braves, giving up one earned run while allowing one hit last time out. Across the diamond, Walker Buehler is scuffling — making his 25th start of the season with a 4.88 ERA in 114⅓ innings pitched, and his 4.46 pNERD is propped up almost entirely by good luck (positive luck score of 21) that says regression is coming, not improvement. San Diego's 9.96 tNERD is the headliner among team components — elite bullpen, strong fielding and baserunning, and a broadcast crew rated highly enough to matter. The Mets counter with a solid barrel-rate profile but a lineup that's been quietly punchless, not helped by Juan Soto's injured-list absence. At 14.29 gNERD, this sits comfortably above both the historic and today's averages — worth a look mostly for McLean's arm.

Miami Marlins @ Philadelphia Phillies, 3:40p

Summary

Cristopher Sánchez is quietly having a career year, and this NL East scrap has real playoff stakes attached, making it the day's best watch. Sánchez owns a 15-4 record with a 2.54 ERA and 181 strikeouts across 25 starts, and he's made a habit of torching Miami specifically, going 3-0 with a 1.06 ERA in 7 appearances against the Marlins. His a high-70s wipeout changeup and heavy sinker generate soft ground-ball contact and elite swinging-strike rates, backing up a pNERD of 10.16 built on a sparkling xFIP- and top-shelf whiff rate — comfortably above today's average pitcher score of 4.11. Across the mound, Janson Junk is replacement-level filler (2.64 pNERD, shaky strike-throwing marks), so don't expect a pitching duel. The teams themselves make up for it: Miami's 9.18 tNERD is buoyed by strong baserunning, a young/cheap roster, and some positive regression given a big underperformance-luck reading, while Philadelphia's b bullpen and baserunning numbers keep their 5.78 respectable despite a batting-runs slump. With this being the 11th meeting between these teams this season and the season series tied 5-5, and both clubs jockeying for playoff position, there's context to go with the numbers. Overall gNERD of 13.88 sits well above both the historical and today's averages — worth your evening.

Baltimore Orioles @ Tampa Bay Rays, 3:05p

Summary

Not a marquee slugfest, but a legit pitching duel with a fun subplot: Brandon Young returning to the town where his teammate's perfect-game-breaking bloop last summer nearly wasn't. Young carries a 3.33 FIP-adjacent line and a 9-3 record into Tropicana Field, still chasing the shadow of the eight-inning gem he authored against Houston last August. Across the mound, Shane McClanahan brings his fastball-heavy four-seamer and quick pace — a 4.87 xERA over his previous three starts aside, his 6.28 pNERD is comfortably above average, built on plus velocity, a tidy strikeout rate, and a snappy 17.1-second pace that keeps at-bats brisk. The Rays (74-49, first in the AL East) are trying to snap a small skid while hosting an Orioles club that's actually won three straight and is scrapping for a wild-card spot despite sitting well back in the division. Tampa Bay's tNERD gets a lift from a thrifty payroll and from Junior Caminero's 35-homer bat, plus a Luck figure suggesting they've been quietly underperforming their skill metrics — room to get better, not worse. Overall gNERD of 10.63 sits almost exactly at the historical middle, a solid, unspectacular Monday watch.

St. Louis Cardinals @ Cincinnati Reds, 10:40a

Summary

A rookie showcase wrapped in a scheduling headache, with more juice from the roster ledger than from the arms on the mound. St. Louis and Cincinnati are packed into a brutal week where they'll play 5 games in 4 days against the Cincinnati Reds beginning with a day/night doubleheader on Monday, and this opener leans on a call-up story: Quinn Matthews gets the ball for the Cardinals against Chase Petty for the Reds. Mathews' pNERD sits at zero for lack of data, but the scouting report is intriguing — his major-league sample is small, but he has been very effective at Triple-A this season with a 3.27 ERA and a 1.23 WHIP. The real hook is the rookie race: this matchup features the two frontrunners for National League Rookie of the Year, Sal Stewart and JJ Wetherholt, with Wetherholt the slight favorite despite Stewart having the hotter bat in the second half. On the NERD ledger, the Cardinals (6.02 tNERD) look sneaky-fun thanks to elite fielding and a young, cheap roster, while the Reds (4.73) get juiced by barrel rate but drag from a punchless bullpen. A 10.38 gNERD is right around today's middle of the pack — watchable for the storylines, not the arms.

St. Louis Cardinals @ Cincinnati Reds, 3:40p

Summary

A modest gNERD tells the story here: this is a fine game, not a must-watch one, wedged into a chaotic five-games-in-four-days series between two teams heading in opposite directions. At 9.47, tonight's gNERD sits below the historic median and roughly in line with today's slate average, driven more by team quality than pitching fireworks.

The Cardinals bring the better team NERD (6.02 vs 4.73), fueled by a brutal week where they'll play 5 games in 4 days against the Cincinnati Reds and a roster that's young and cheap enough to post strong z-scores in payroll and age, though a shaky bullpen drags them down. The Reds counter with an ugly batting-runs figure but some positive regression looming given their luck score, and they're already shorthanded with Spencer Steer nursing a wrist injury and Hunter Greene still out with an elbow issue.

On the mound, Andre Pallante has quietly been a revelation for the Cardinals this season, following a poor 2025 with a much-improved 3.46 ERA in 23 starts, and his above-average velocity keeps his pNERD respectable. Rhett Lowder, meanwhile, is scuffling with a 5.15 ERA in 21 total appearances this season, including 18 starts, and his subpar xFIP- and swinging-strike rate mostly cancel out the youthful appeal. Watch if you're into NL Central squabbling; skip if you need marquee arms.

Detroit Tigers @ Pittsburgh Pirates, 4:05p

Summary

A middling matchup on paper that carries some real playoff stakes for Detroit and rock-bottom stakes for a Pittsburgh team spiraling out of contention. Valdez is trying to shake off a rough outing against Cleveland where he allowed four runs on six hits and five walks while striking out three over 5 2/3 frames, though the modest pNERD (3.02) reflects unremarkable strikeout stuff and a slow pace rather than any real ace-level upside. Mlodzinski has been pressed into emergency duty since Pittsburgh lost Mitch Keller for the season to a torn arm muscle, and it hasn't gone well — he's taken over as the starting pitcher the last two games Keller would've started, giving up nine earned runs over 5.1 innings for a 15.19 ERA in two defeats. The Pirates carry the better tNERD (6.65) thanks to solid batting and baserunning, offset by shaky fielding, while Detroit's roster skews toward payroll and batted-ball quality without much juice elsewhere. PNC Park's spacious outfield tends to suppress scoring, and with a gNERD of 8.73 — below both the historical and today's averages — this slots in as a background game rather than appointment viewing, useful mainly if you care about Detroit's wild-card push.

Arizona Diamondbacks @ Boston Red Sox, 4:10p

Summary

This one's a bottom-tier matchup that only rookie curiosity and Fenway ambiance can save. With a gNERD of 8.01 — comfortably below today's average of 10.04 and well under the historical median — this game leans on lineup depth rather than pitching intrigue for its watchability.

The Diamondbacks send out 22-year-old rookie Mitch Bratt, whose pNERD sits at a near-invisible 0.03. His command hasn't caught up to his stuff: Bratt has a 3.74 ERA and 1.40 WHIP through seven starts, with an 18% strikeout rate and an elevated 13% walk rate. His xFIP- of 133 backs up the shaky peripherals, though his youth at least keeps his NERD score from cratering into negative territory. Boston counters with a bulk-innings arm behind the "TBD" listing — Ryan Brault, in what's described as an unusual bulk-pitcher role for a Red Sox club that has quietly dropped six of eight, so don't expect length or dominance from either side. On the offense/defense ledger, Boston's bullpen (tNERD-boosting at 1.47) and Arizona's baserunning and glove work are the more compelling storylines than anything happening on the mound today.

Los Angeles Dodgers @ Colorado Rockies, 5:40p

Summary

A star returning from the injured list against a last-place team at altitude — decent theater, if not much of a nail-biter. Blake Snell is back in a Dodgers uniform after three months away following elbow surgery, and Blake Snell was terrific last Tuesday in his return from three months on the injured list with 10 strikeouts in six strong innings against the Kansas City Royals. His pNERD reads a flat 0.00 simply because we lack meaningful 2026 sample data, not because he's been bad — in fact he's running at 15 strikeouts per nine in 2026, and his two career starts against Colorado produced 11 K and 15 K in six shutout innings each, so don't let the zero fool you. Across the mound, Sugano owns a well-worn punching bag reputation against this specific Dodgers lineup — Sugano carries a 7.82 ERA across three 2026 starts against this exact lineup, with some of the most lopsided BvP numbers in the game for Ohtani, Freeman, and Muncy — and his xFIP-driven components confirm he's not missing many bats. The tNERD gap is the story: Dodgers at 8.56 versus Rockies at a lowly 1.34, reflecting LA's power, defense, and bullpen depth against Colorado's league-worst batting runs. At a 7.59 gNERD — below today's 10.04 average and well under the historic 10.81 mean — this is watchable mostly for Snell's strikeout stuff and the Coors Field hitting fireworks he'll try to avoid, not for competitive drama.

Atlanta Braves @ Minnesota Twins, 4:40p

Summary

Skip the low-key stuff — this is a middling matchup on paper, propped up mostly by the Braves being the Braves. Atlanta's tNERD (5.67) comfortably outpaces Minnesota's (2.82, well below the historic median), and neither Martín Pérez nor Bailey Ober bring much heat to the mound — both sit in the bottom half of pNERD scores historically, and their fastballs clock in barely above 88-89 mph.

The storylines carry more juice than the peripherals: Pérez anchors a rotation that's stayed functional despite losing Spencer Strider to a 60-day IL stint, and carries a 2.96 ERA giving Atlanta a reliable arm. Meanwhile Minnesota is thinning out — Joe Ryan is currently on the 15-day IL with a glute injury, and the Twins' rotation depth behind Taj Bradley is shaky. It's also a rare visit — this is the first time Atlanta will face Minnesota this season. Atlanta's -39 team luck score is notably negative (they're underperforming their skill-based numbers), so positive regression could be lurking, but Ober's xFIP- of 118 flags him as genuinely hittable rather than unlucky. At 7.01, this gNERD sits below both the historic and today's-slate averages — pleasant background baseball, not appointment viewing.

Athletics @ Kansas City Royals, 4:40p

Summary

Skip this one unless you have a soft spot for last-place baseball. Two teams playing out the string—Kansas City sits 15 games back in the AL Central, Oakland 13.5 back in the AL West, and neither has October on its mind—square off in what amounts to a scouting exercise for 2027. The Royals are 3-7 and the Athletics 4-6 over their last ten, so nobody's arriving hot, and both bullpens are the problem: Kansas City's relief corps rates dead last among our team metrics (-2.55) while Oakland's fielding is nearly as leaky. Michael Wacha gives Kansas City the more useful arm here, with a respectable 105 xFIP- and quick pace, but Mason Barnett has been scuffling—an ugly 121 xFIP-, shaky command, and a slow tempo that won't help. At 5.44, the gNERD score sits near the bottom of today's slate (which ranges from 5.44 to 14.98) and well below the historical average near 10.8. There's nothing here to chase—just two rebuilding rosters testing themselves against comparable competition.
