Susana underwent surgery last week to repair a right lat tear, Spencer Nusbaum of The Washington Post reports.
Susana suffered the injury while pitching for Double-A Harrisburg in late August, and the determination was made last week that surgery was the best course of action. It's unclear how long the 21-year-old's rehab will take, but he could 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.

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

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

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

Nationals' Jarlin Susana: Among seven reassigned
Rotowire
The Nationals reassigned Susana to minor-league camp Tuesday, Spencer Nusbaum of The Washington Post reports.
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.
Susana hit 100 mph with his fastball in his first bullpen session of the spring and looked dominant during a live batting practice session Wednesday as he worked in his slider, Mark Zuckerman of MASN Sports reports.
The 20-year-old right-hander will continue to be developed as a starter in the minors, but Susana could likely make an immediate impact in the majors if he got fast-tracked as a reliever. Improving his command and refining his changeup will be Susana's main goals in 2025 after he posted a 4.34 ERA, 1.31 WHIP and eye-popping 157:48 K:BB through 103.2 innings last season split between Single-A and High-A.

Nationals' Jarlin Susana: Dominant finish at High-A
Rotowire
Susana logged a 2.40 ERA, 1.13 WHIP and 27 strikeouts in 15 innings over his final three starts for High-A Wilmington.
The big righty had a pair of 10-strikeout performances to put a bow on his age-20 campaign. His fielding-independent stats paint a better picture (FIP and xFIP below 3.00 at Single-A and High-A) than his 4.34 ERA and 1.31 WHIP in 103.2 innings across the two levels. Susana's 35.4 percent strikeout rate ranked fourth in the minors among pitchers who threw 100-plus innings this season.

Nationals' Jarlin Susana: Dazzles versus big-leaguers Tuesday
Rotowire
Susana struck out two in a perfect eighth inning during Tuesday's exhibition game between the Nationals and the organization's top prospects.
Just a few days after his 20th birthday, Susana nearly produced an immaculate inning against big-league hitters, but after Joey Gallo and Riley Adams struck out on six pitches, Jacob Young was able to weakly ground out. Per Bobby Blanco of MASN Sports, Susana topped out at 102.4 mph with his fastball and sat around 101 mph while also working in his potentially plus slider. Part of the package the Nats received for Juan Soto from the Padres, Susana made 16 starts at Single-A Fredericksburg last season and posted a disappointing 5.55 ERA and 56:38 K:BB over 58.1 innings. Washington isn't going to give up on him working out as a starting pitcher quite yet, but if he were to shift to a relief role, the young flamethrower could climb the ladder very quickly.

Nationals' Jarlin Susana: Holding his own at Single-A
Rotowire
Susana has a 3.81 ERA, 1.35 WHIP and a 52:30 K:BB in 49.2 innings through 13 starts for Single-A Fredericksburg.
The 6-foot-6 righty is one of the youngest pitchers in full-season ball, so he should be graded on a bit of a curve. Susana obviously needs to work on cutting his 14 percent walk rate, but he has been more consistent lately. The 19-year-old hurler has logged between four and five innings in eight straight starts while posting a 3.24 ERA, 1.20 WHIP and 30:14 K:BB in 33.1 innings over that stretch.
