Jarlin Susana - MLB News, Rumors, & Updates | FOX Sports

Undergoes lat surgery Susana underwent surgery last week to repair a right lat tear, Spencer Nusbaum of The Washington Post reports.

Impact Susana suffered the injury at Double-A Harrisburg in late August, and it was determined last week that surgery was the best course of action. It's unclear how long the 21-year-old's rehab will take, but it's possible he'll be limited at the start of spring training. Susana posted a 3.51 ERA and 95:34 K:BB over 56.1 innings covering 14 starts between High-A Wilmington and Harrisburg in 2025.

Diagnosed with lat strain Susana has been diagnosed with a right lat strain, Andrew Golden of The Washington Post reports.

Impact Susana had to be removed from his last start at Double-A Harrisburg with the injury. He will meet with the Nationals' medical staff soon to discuss his options, but the injury will surely prevent Susana from pitching again this season. The 21-year-old has collected a 3.51 ERA and 95:34 K:BB over 56.1 innings covering 14 starts between High-A Wilmington and Harrisburg in 2025. Susana previously missed time this season due to a sprained elbow.

Dealing with triceps soreness Susana was diagnosed with right triceps soreness after being removed from his start Saturday with Double-A Harrisburg, Mark Zuckerman of MASNSports.com reports.

Impact The 21-year-old allowed three runs over 1.2 frames prior to exiting the contest, which ended a stretch of five consecutive starts in which he surrendered one or fewer runs. The severity of the injury isn't yet known, leaving Susana's availability for his next turn through Harrisburg's rotation up in the air.

Fans career-high 13 at Double-A Susana struck out 13 over five innings for Double-A Harrisburg on Tuesday, allowing one run on two hits and two walks.

Impact The 13 Ks were a career high for the 21-year-old right-hander, and per Jesse Borek of MLB.com, Susana's fastball topped out at 103 mph in the outing. Over six starts since returning from a UCL sprain in late July, Susana has posted a 2.28 ERA, 0.89 WHIP and 44:8 K:BB in just 23.2 innings. If he can stay healthy, he seems ticketed for a big-league debut in 2026, potentially adding another building block to a Nationals rotation that already features two young pitchers with ace-level upside in MacKenzie Gore and Cade Cavalli.

Activated off minor-league IL Susana (elbow) was activated from the 7-day injured list at Double-A Harrisburg on Thursday, Bobby Blanco of MASNSports.com reports.

Impact Susana hasn't pitched for Harrisburg since early May after being diagnosed with a right elbow sprain, but he made three rehab starts with High-A Wilmington and had a 16:2 K:BB over nine innings. The righty has collected a 3.86 ERA and 54:22 K:BB over 35 frames covering nine starts between the two stops this season.

Shut down with elbow sprain Double-A Harrisburg placed Susana on its 7-day injured list Saturday due to a Grade 1 UCL sprain in his right elbow, Mark Zuckerman of MASNSports.com reports.

Impact One of Washington's top pitching prospects, Susana was diagnosed with the injury following his most recent start with Harrisburg on May 4. Nationals manager Dave Martinez said that a Grade 1 sprain represents a "best-case scenario" for the 21-year-old righty, but he'll still be shut down from throwing for at least two weeks. The hard-throwing Susana has racked up 38 strikeouts over 26 innings with Harrisburg this season, but he's issued 20 walks and has turned in a 1.69 WHIP.

Among seven reassigned The Nationals reassigned Susana to minor-league camp Tuesday, Spencer Nusbaum of The Washington Post reports.

Impact Susana is the most notable among the seven the Nats cut from big-league camp. The big right-hander has yet to advance past A-ball, so he wasn't under real consideration for the Opening Day roster, but Susana is among the club's top prospects following a 2024 campaign which featured 157 strikeouts over 103.2 frames. Susana finished last season at High-A Wilmington and could either return there to start 2025 or get bumped up to Double-A Harrisburg.

Impact One of the Nationals' top pitching prospects, Susana has yet to pitch above High-A as he continues to be developed as a starter. He'll turn 21 just before Opening Day, and his 157:48 K:BB over 103.2 innings between Single-A and High-A last season highlights both his tremendous upside and the amount of work he still needs to do to get his control and command to a level that will allow him to stick in the rotation.
