Imanaga has been diagnosed with a mild left hamstring strain that is expected to hold him out for more than two weeks, Bruce Levine of 670TheScore.com reports.

This update likely means that Imanaga will miss more than the minimum while on the injured list. Manager Craig Counsell stated that the two-week timeline was set as a precaution, so it doesn't appear that the club is in any hurry to rush the southpaw back into action. A clearer timeline for Imanaga's return should come into focus as he begins to make progress in his rehab.

Smith-Shawver (2-2) earned the win Monday against the Reds, allowing one hit and four walks over eight scoreless innings. He struck out five.

After departing his April 29 outing due to taking a comebacker off his right elbow, Smith-Shawver showed no ill effects in this 99-pitch performance. The 22-year-old carried a no-hitter into the eighth inning until Santiago Espinal opened the frame with a single. Smith-Shawver now sports a 3.00 ERA, 1.37 WHIP and 27:13 K:BB across 27 innings. He currently lines up to make his next start at Pittsburgh this weekend.

Singer (4-2) took the loss Monday at Atlanta, allowing four runs on seven hits and two walks over six innings. He struck out two.

The Cincinnati right-hander generated just three whiffs in this 102-pitch outing, as he notched a season-low two Ks. Singer coughed up all four runs in the third inning, capped by a Matt Olson inside-the-park home run. Through 39.1 innings, Singer has pitched to a 3.66 ERA, 1.14 WHIP and 38:14 K:BB. The 28-year-old is currently scheduled to make his next start at Houston this weekend.

Irvin won't make his scheduled start Monday against the Guardians after the game was postponed due to inclement weather, Bobby Blanco of MASNSports.com reports.

Irvin has been named the starter for Game 1 of his team's doubleheader Tuesday following the announcement that Monday's game has been postponed. He'll look to bounce back from his worst outing of the 2025 season, surrendering six runs on eight hits and three walks while striking out two over six innings against the Phillies on Wednesday.

Burnes (shoulder) threw on flat ground Monday, Jack Sommers of SI.com reports.

Burnes is not making his scheduled start Monday against the Mets after experiencing fatigue in his right shoulder over his past two outings. It's the first time he's missed a start since he entered the rotation on a full-time basis in 2020. However, Burnes' session of catch Monday appeared to go well, and he and the Diamondbacks remain optimistic he can avoid the 15-day injured list and start this weekend versus the Dodgers.

Cubs manager Craig Counsell said Monday that Horton is a possibility to enter the rotation in place of the injured Shota Imanaga (hamstring), Tony Andracki of Marquee Sports Network reports.

Counsell also mentioned Chris Flexen as an option, and Flexen could be the favorite to draw a start this weekend against the Mets since he's already on the 26-man and 40-man rosters, while Horton is not. However, Horton has put himself in the conversation by posting a 1.24 ERA, 0.86 WHIP and 33:13 K:BB over 29 innings at Triple-A Iowa this season. Imanaga will miss at least two starts after landing on the 15-day injured list Monday.

Brewers manager Pat Murphy said Monday that Peralta (groin) hasn't undergone imaging, but the pitcher could be given "a day or two" of extra rest before his next start, Curt Hogg of the Milwaukee Journal Sentinel reports.

Peralta was lifted early from Sunday's start versus the Cubs due to groin soreness. A team off day Thursday affords Peralta with at least one day of extra rest, and the Brewers could give him an additional day by having Tobias Myers start Saturday on normal rest and giving Peralta the ball Sunday in Tampa Bay. More information on Peralta's status should be available later this week.

Nationals manager Dave Martinez said that Gore remains sore Monday after tweaking his ankle during Sunday's start in Cincinnati but is feeling a lot better, Andrew Golden of The Washington Post reports.

Gore slipped and fell on a wet mound during the fifth inning versus the Reds and hurt his ankle in the process. He finished that frame and likely would have been removed even if he was totally healthy, given that he needed 100 pitches to cover five frames. While Gore is a little banged up, it does not appear at this point he's in any danger of missing his next scheduled start Sunday against the Cardinals. It helps that he will have six days of rest between outings.

Atlanta manager Brian Snitker said that Strider (hamstring) advanced to long-toss throwing Sunday, David O'Brien of The Athletic reports.

The activity marks a small step forward for Strider, who had been limited to playing catch from shorter distances since straining his right hamstring Monday. Snitker noted, however, that Strider hasn't yet been cleared for mound work, so the right-hander is most likely at least a couple weeks away from coming off the 15-day injured list. AJ Smith-Shawver should continue to maintain a spot in Atlanta's rotation until Strider is ready for activation.

The Cubs placed Imanaga (hamstring) on the 15-day injured list Monday, Maddie Lee of the Chicago Sun-Times reports.

Imanaga will hit the shelf after straining his left hamstring in his start during Sunday's loss to the Brewers. Though he underwent an MRI on Monday that confirmed the injury, the severity of the hamstring strain isn't known, making it uncertain whether Imanaga will have a chance at being ready to return from the IL when first eligible May 20. The Cubs haven't named an immediate replacement in the rotation for Imanaga, but Chris Flexen could be moved from the bullpen into a starting role, or prospect Cade Horton could be called up from Triple-A Iowa to fill the void.
