The Los Angeles Dodgers optioned right-hander Emmet Sheehan to Triple-A Oklahoma City on Monday, manager Dave Roberts told Fabian Ardaya of The Athletic. Reliever Paul Gervase has been called up in a corresponding move to give the Dodgers a fresh bullpen arm. The 26-year-old Sheehan looked great in his return to the big-league starting rotation, albeit in just two starts, allowing one earned run on five hits while walking two and striking out 15 in 11 2/3 innings against the Cincinnati Reds and Miami Marlins. He will go back down to the minors for now but could resurface with the Dodgers out of the bullpen for the playoffs in October. The former sixth-rounder in 2021 from Boston College has gone 5-8 for the Blue this year with a 4.79 ERA (4.48 FIP) and 1.21 WHIP with a career-high 123 strikeouts and 32 walks in 107 innings pitched across his 22 starts in just his third big-league campaign. Despite his inconsistency, Sheehan is still an intriguing developmental arm for the Dodgers with plenty of swing-and-miss stuff.

Los Angeles Dodgers right-handed reliever Edwin Diaz (neck), who allowed five earned runs on two hits with three walks and one strikeout in two-thirds of an inning in a minor-league rehab outing on Sunday, will have another outing for Triple-A Oklahoma City on Wednesday, according to Sonja Chen of MLB.com. Diaz was supposed to have a short rehab assignment before returning from the 15-day injured list, but the Dodgers have not seen enough from him. "He needs to pitch better. It hasn't been good," manager Dave Roberts said. In 3 1/3 total rehab innings, the 32-year-old veteran reliever has allowed six runs while walking four and striking out seven. Diaz also missed a large chunk of the 2026 season after having surgery to remove loose bodies from his right elbow, and he has been out since the middle of August with inflammation in his neck. When active, the three-time All-Star has been a massive free-agent bust for the Dodgers, going 2-2 with an 11.85 ERA, 2.56 WHIP, seven saves, and 19 strikeouts in 13 2/3 innings at the major-league level. Diaz almost certainly will be pitching in low-leverage situations out of the bullpen when he returns from the IL, and if he continues to pitch poorly, he could be left off the Dodgers' postseason roster in October.

Chicago Cubs shortstop Dansby Swanson (oblique) will play on a minor-league rehab assignment on Tuesday and Wednesday with the Triple-A Iowa Cubs, according to Taylor McGregor of the Marquee Sports Network. If all goes well, Swanson will join the team for Friday's series opener against the division-rival Cincinnati Reds. The 32-year-old veteran shortstop has been on the shelf since mid-August with an oblique strain, but he looks ready to return to action this weekend to try to help the Cubbies get into the playoffs for the final couple of weeks of the regular season. The two-time All-Star will be returning to a .216/.300/.404 slash line with a .704 OPS, 18 home runs, 66 RBI, 17 stolen bases, and 78 runs scored across his 119 games and 458 plate appearances. While Swanson still has an outside chance at his second straight 20-20 season in his 11th year in the majors, he has hit a career-worst .216 this season with just a .300 on-base percentage, which ties his career low from a season ago. In 27 games in the second half before his oblique strain, Swanson had just two home runs, eight RBI, and five steals after he hit 16 long balls in the first half of 2026.

San Francisco Giants first baseman Rafael Devers (core) will have season-ending surgery on Tuesday in Philadelphia to fix a left-sided core-muscle injury, according to Zach Sweet of MLB.com. The Giants said they will provide an update on his recovery timeline after the surgery. The Giants placed Devers on the 60-day injured list on Sunday, putting an end to his 2026 campaign. The 29-year-old left-handed slugger will finish his first full season in the Bay Area with a .258/.340/.525 slash line, an .865 OPS, 37 home runs, 98 RBI, and 88 runs scored in 148 games and 633 plate appearances. Devers is currently leading the league with 36 doubles after a recent offensive barrage in the second half of the season. The three-time All-Star went off in August with a .272 average (28-for-103) with eight home runs, five doubles, 18 RBI, and 22 runs scored in 28 games played. Devers got off to an icy start in 2026 by hitting .207 (25-for-121), but he turned things around quickly in May and finished with his second straight 35-plus-homer season. The Dominican first baseman has reached the 30-homer mark in four of the last six seasons with the Giants and Boston Red Sox.
