Assad is expected to move to the bullpen later this week with Jameson Taillon (groin) set to return from the 15-day injured list to start Wednesday's game in Atlanta, Jordan Bastian of MLB.com reports.

Assad has made five starts for the Cubs this season after recovering from a strained oblique, turning in a 4.62 ERA and 1.26 WHIP across 25.1 innings. However, Taillon's imminent return leaves Chicago with a full rotation that also includes Shota Imanaga, Cade Horton, Matthew Boyd and Colin Rea. Assad pitched well in a swingman role back in 2023, when he compiled a 3.05 ERA and 1.23 WHIP over 109.1 innings across 10 starts and 22 relief appearances. The righty will likely once again give the Cubs some length out of the bullpen, and he's capable of making a spot start if needed.

Eagen has a 3.77 ERA, 1.33 WHIP and 16:9 K:BB in 14.1 innings across three starts for Double-A Amarillo.

Eagen, a third-round pick in 2024, logged a 2.49 ERA, 1.06 WHIP and 132:41 K:BB in 97.2 innings for High-A Hillsboro before getting promoted to Double-A on Aug. 19. He capped his run at High-A in impressive fashion, striking out 21 over 13 scoreless innings in his final two starts for the Hops. His performance at Double-A has been uneven, and his walk issues from earlier in the year have popped back up. The 6-foot-4 righty works in the low 90s with his four-seamer, but the pitch has excellent movement and plays better than its velocity. Eagen's low-80s curveball is his top put-away pitch, and he'll mix in a solid slider and seldom-used changeup. Eagen is up to 112 total innings in what has been a highly-successful debut season.

Montas will undergo Tommy John surgery on his right elbow Tuesday, Jon Heyman of the New York Post reports.

A full UCL repair had been considered likely, and now it's official. The operation will likely sideline Montas until the 2027 campaign. Montas proved to be a disastrous investment for the Mets, posting a 6.28 ERA in seven starts and two relief appearances, and he will now undoubtedly exercise a $17 million player option for 2026.

Doyle was promoted from Single-A Palm Beach to Double-A Springfield on Tuesday.

Doyle made his professional debut with Palm Beach this past weekend, allowing one run while striking out three over 1.2 frames. Palm Beach's season is now over, but the fifth overall pick in the 2025 First-Year Player Draft will continue pitching at the Double-A level as he gets his feet wet in pro ball.

Mikolas did not factor into the decision Monday, allowing two runs on four hits and a walk over five-plus innings against Seattle. He struck out two.

The veteran starter held Seattle scoreless through five innings before running into trouble in the sixth frame, allowing two baserunners without recording an out before Gordon Graceffo came on and let both inherited runners -- plus two more -- cross the plate. While the season has been underwhelming overall for Mikolas, he's pieced together a solid stretch lately, logging a 2.25 ERA and 1.00 WHIP over 16 innings across his three most recent starts.

Lodolo did not factor into the decision Monday, allowing two hits and a walk over five scoreless innings against the Padres. He struck out two.

Lodolo returned from an illness that sidelined him for a start and turned in a sharp five-inning performance, though the Reds' bullpen gave away the lead and left him with a no-decision. The left-hander has quietly been excellent this season, posting a 3.10 ERA and 1.03 WHIP over 139.1 innings in 25 starts.

Darvish did not factor into the decision Monday, allowing three runs on six hits and no walks over 5.2 innings against the Reds. He struck out seven.

Darvish surrendered a leadoff homer to TJ Friedl but settled in to grind out 5.2 serviceable innings, keeping the Padres in a game they ultimately won in 10 innings. It's been a challenging season for the veteran right-hander, who didn't debut until July 7 due to an elbow injury. Through 12 starts, he owns a 5.65 ERA and 1.17 WHIP across 57.1 innings as San Diego hopes he can find his form heading into the postseason.

Dollander allowed one run on one hit and two walks while striking out five over five innings in a no-decision versus the Dodgers on Monday.

Dollander did his part, but the Rockies got no-hit for the first eight innings of the game. They were able to scrape together a run to keep Dollander from taking the loss, and it's encouraging he pitched well after allowing 10 runs over 9.1 innings across his first two career starts against the Dodgers. Despite this positive step forward, he still has a 6.52 ERA, 1.55 WHIP and 82:49 K:BB through 98 innings over 21 starts this season. The rookie right-hander's next start is projected to be in San Diego this weekend.

Glasnow (2-3) threw seven no-hit innings, allowing one run on two walks while striking out 11 and earning the win over the Rockies on Monday.

Glasnow was scratched from starting Friday versus the Orioles due to back tightness, but the extra rest appears to have done wonders for him. He wasn't limited in Monday's start, throwing 65 of 105 pitches for strikes in his best outing of the season. Glasnow lowered his ERA to 3.21 with a 1.03 WHIP and 92:34 K:BB through 75.2 innings over 15 starts this season. Assuming he comes out of this impressive effort in fine shape, he's projected to make his next start at home in a tough matchup versus the Phillies next week.

Webb (14-9) allowed four runs (one earned) on five hits and two walks while striking out seven over six innings to earn the win over the Diamondbacks on Monday.

The Giants fell behind early after an error led to three runners eventually crossing the plate in the second inning. Webb was steady enough to overcome that, and the Giants' offense took over in the sixth to help him secure his fourth win in his last five starts. He's allowed a total of 10 runs (seven earned) with a 33:6 K:BB across 31 innings in that span. Overall, Webb has a 3.12 ERA, 1.22 WHIP and a career-high 201 strikeouts through 184.2 innings over 30 starts this season. The 28-year-old's next start is projected to be at home versus the Dodgers this weekend as he attempts to tie his career high of 15 wins.
