Merrill Kelly SP | ARI
Diamondbacks' Merrill Kelly: Earns 10th win of season Wednesday
Kelly (10-14) earned the win Wednesday against the Rockies after allowing two runs on four hits and a walk while striking out two over 5.1 innings.
Kelly worked with a four-run lead after the first inning and kept Colorado from completing a comeback, allowing an RBI double to Adael Amador in the second and a Hunter Goodman sacrifice fly in the third. The veteran has struggled with consistency in recent weeks, and for the most part, his results have been underwhelming, with three or more earned runs allowed in six of his last 10 starts. He closes out the regular season with a 4.94 ERA, 1.46 WHIP and 113:70 K:BB across 29 starts and 162 innings.

Ethan Pecko SP | HOU
Astros' Ethan Pecko: Struggles as starter
Pecko allowed three runs on four hits and two walks while striking out two over 2.2 innings in a no-decision versus the Mariners on Wednesday.
Pecko worked well as a bulk reliever in his two last appearances, but a return to a starting role didn't go so well. This was his shortest of seven outings (five starts) in the majors. He ends the regular season at a 4.31 ERA, 1.21 WHIP and 21:14 K:BB through 31.1 innings. It's unclear if Pecko has done enough to earn a spot on a postseason roster should the Astros make the playoffs, but he'd likely function as a reliever if that happens.

George Kirby SP | SEA
Mariners' George Kirby: Struggles in last start of season
Kirby allowed four runs on six hits and three walks while striking out five over five innings in a no-decision versus the Astros on Wednesday.
Kirby struggled down the stretch, allowing 31 runs (30 earned) with a 36:19 K:BB over his last 42.2 innings across eight starts. It was a tough year overall for the right-hander, who ends up with a 9-11 record, 4.33 ERA, 1.40 WHIP and 148:47 K:BB through 174.2 innings over 30 starts. Those are career-worst marks across the board, with the 2.4 BB/9 standing out as particularly poor for a pitcher best known for his control.

Yoshinobu Yamamoto SP | LAD
Dodgers' Yoshinobu Yamamoto: Takes loss against Padres
Yamamoto (14-9) allowed four runs (two earned) on five hits, a walk and a hit batsman while striking out four over six innings to take the loss versus the Padres on Wednesday.
Yamamoto earned a third straight quality start, though the Padres' pair of runs in the fifth inning were a product of his own throwing error. The right-hander has had few stumbles this season, pitching to a 2.53 ERA, 0.87 WHIP and 182:42 K:BB over 185 innings through 28 starts. His regular season is done, so expect Yamamoto's next appearance to come in the NLDS.

Robbie Ray SP | SD
Padres' Robbie Ray: Short outing against Dodgers
Ray allowed one run on seven hits and a walk while striking out two over 3.1 innings in a no-decision versus the Dodgers on Wednesday.
Ray's short outing came down to inefficiency -- he needed 84 pitches (55 strikes) to get the 10 outs. It's been a bumpy September for the veteran lefty, who has allowed 14 runs over 16.2 innings with a 14:11 K:BB this month. His regular season is likely done at a 13-8 record with a 3.59 ERA, 1.35 WHIP and 140:84 K:BB over 31 games (30 starts) between the Padres and the Giants. Ray is lined up to pitch in the wild-card series in the likely event the Padres secure a playoff spot.

Walbert Urena SP | LAA
Angels' Walbert Urena: Sour finale to rookie year
Urena (9-11) allowed five runs on seven hits, a walk and a hit batsman while striking out two over four innings to take the loss versus the Athletics.
Urena mostly had a strong rookie season, but he ended it on a sour note with this start. This was just the third time all year he was tagged for five or more runs in a game. He ends his campaign at a 2.97 ERA, 1.23 WHIP and 142:68 K:BB through 148.1 innings over 29 games (27 starts). Urena still has some room to grow, particularly when it comes to cutting back walks, but he was effective at limiting home runs (0.6 HR/9), which bodes well for the long run.

Joe Musgrove SP | SD
Padres' Joe Musgrove: Playing catch, return TBD
Musgrove (elbow) has been regularly playing catch, but the timeline for a potential return to action remains unclear, MLB.com reports.
Musgrove has yet to pitch for the Padres this season. as he's struggled to recover from the Tommy John surgery he underwent in October of 2024. The veteran hurler fared mostly well during a four-game minor-league rehab stint in August, but he was ultimately pulled off the assignment because he was having trouble recovering between starts. There's still a chance San Diego could activate Musgrove to see what he can give them, but he'd be limited to a relief role if that were to happen.

Jeffrey Springs SP | ATH
Athletics' Jeffrey Springs: Short start Wednesday
Springs allowed three runs on five hits, a walk and a hit batsman while striking out three over 4.1 innings in a no-decision versus the Angels on Wednesday.
Springs threw 53 of 84 pitches for strikes in this outing, but he was tagged for two home runs. He hadn't given up a long ball over his first three starts in September, though he surrendered a total of 11 runs over 19.2 innings this month. The southpaw is likely done for the season after this outing, having gone 4-14 with a 6.18 ERA, 1.46 WHIP and 112:57 K:BB over 142.2 innings across 29 starts.

Seth Lugo SP | KC
Royals' Seth Lugo: Rough third inning in no-decision
Lugo allowed four runs on seven hits and no walks while striking out three batters over 3.1 innings in a no-decision against the White Sox on Wednesday.
Lugo got six straight outs to start the game, but allowed all of the games' damage in the third inning when the White Sox got four runs off of five hits and 2 hit-by-pitches. The 36-year-old leaves this start allowing the most hits (200) and second most earned runs (99) in the American League. This is likely Lugo's last outing of the 2026 season.

Matthew Liberatore SP | STL
Cardinals' Matthew Liberatore: Secures first win since July
Liberatore (6-14) gave up one run on six hits and no walks while striking out six over 5.2 innings to earn the win Wednesday versus the Pirates.
Liberatore picked up his first victory since July 11, which came against Atlanta just before the All-Star break. During the winless stretch, the left-hander tossed 61.1 innings with a 5.58 ERA and 1.45 WHIP with eight losses in 11 outings. The 26-year-old pitched great Wednesday in Pittsburgh, with the only damage against him coming via a solo homer by Brandon Lowe. It was Liberatore's final start of the campaign, and he'll end 2026 with a disappointing 5.23 ERA, 1.47 WHIP and 154:55 K:BB across 155 innings.
