Cronin (back) was designated for assignment by the Nationals on Monday, Andrew Golden of The Washington Post reports.

EDGE Analysis

The Nationals did some 40-man roster housecleaning Monday and Cronin has lost his spot. Cronin, who has never appeared in the majors, underwent back surgery in August and it's unclear when he might be ready to pitch again.

Cronin announced Wednesday via his personal Instagram account that he underwent season-ending surgery to address a herniated disc.

EDGE Analysis

Cronin hadn't pitched for Triple-A Rochester since mid-May due to what was a previously undisclosed injury, but the 25-year-old left-hander took to social media to shed more light on his situation. In his post, Cronin noted that he had been dealing with left shoulder and arm pain for two years, but it wasn't until he had his spine examined last month that doctors were able to determine the source of his discomfort. Cronin, who occupies a spot on the Nationals' 40-man roster, is without a clear timeline to resume full baseball activities and may face an uphill battle to gain clearance for the start of spring training.

Cronin (undisclosed) was placed on the 7-day injured list Tuesday at Triple-A Rochester, Bobby Blanco of MASNSports.com reports.

EDGE Analysis

There is no official diagnosis yet, but Cronin had been struggling badly with Rochester this season after looking like one of the more promising young relievers in the Nationals' system last year. He posted a 2.42 ERA with 56 strikeouts over 52 innings between Double-A and Triple-A in 2022. Conversely, he's pitched to a 5.02 ERA and 13:14 K:BB through 14.1 frames this season.

The Nationals optioned Cronin to Triple-A Rochester on Tuesday, Andrew Golden of The Washington Post reports.

EDGE Analysis

Cronin earned a spot on the 40-man roster over the winter after a nice performance between Double-A Harrisburg and Triple-A Rochester. He'll surely debut this season.

Cronin was added to the Nationals' 40-man roster Tuesday.

EDGE Analysis

Cronin split time between Double-A Harrisburg and Triple-A Rochester in 2022, recording a 2.38 ERA and 1.09 WHIP between the two levels. The 25-year-old lefty will likely begin 2023 in Triple-A in preparation for joining Washington's bullpen at some point during the season.

Cronin was promoted to Triple-A Rochester on Friday, Jesse Dougherty of The Washington Post reports.

EDGE Analysis

Cronin was dominant as a reliever at Double-A Harrisburg to begin the season, as he posted a 22:7 K:BB and 0.75 WHIP in 16.1 scoreless innings over 14 appearances to begin the season. The southpaw has served as a non-roster invitee during the last two seasons, and he'll now be rewarded with a promotion to the Triple-A club.

The Nationals announced Wednesday that Cronin would be invited to major-league spring training as a non-roster invitee.

EDGE Analysis

Cronin was part of the Nationals' 60-man player pool in 2020 but spent the entire season at the alternate training site. The southpaw was dominant for Low-A Hagerstown in 2019, posting a 0.82 ERA and 41:11 K:BB over 22 relief innings. The southpaw likely needs more minor-league experience prior to making his debut with the big-league club, but he should have a chance to develop this spring as a non-roster invitee.
