Harrington missed the final few weeks of the season for Triple-A Indianapolis due to a right groin injury, Dominic Campbell of SI.com reports.

EDGE Analysis

It's the same injury that caused Harrington to go on the 7-day injured list Aug. 10, as he threw one inning Aug. 28 and aggravated the injury and had to exit the start early before being shut down for the season. Harrington, who was in the mix for a rotation spot during spring training, had poor overall results in the majors (15 earned runs in 8.2 innings) and minors (5.34 ERA at Triple-A) while tallying 104.2 total frames across the two levels. He shouldn't have any restrictions in spring training but will face an uphill battle in camp to make the big-league roster.

Triple-A Indianapolis placed Harrington on its 7-day injured list Friday due to an unspecified injury.

EDGE Analysis

Indianapolis had previously shelved Harrington on Aug. 10 due to an unspecified injury, and though he was activated Thursday, he made it through just one inning during his start against Buffalo before landing back on the IL a day later. The Pirates haven't shed light on the nature of Harrington's latest setback, but given the timing of the injury, the right-hander could be hard-pressed to pitch again in 2025.

Triple-A Indianapolis placed Harrington on its 7-day injured list Sunday due to an undisclosed injury.

EDGE Analysis

After being demoted Aug. 2, Harrington rejoined the Indianapolis rotation Friday and apparently sustained an injury during that start. The right-hander possesses a spot on the Pirates' 40-man roster, but his injury coupled with his poor numbers at the Triple-A level this season (5.40 ERA, 1.33 WHIP in 95 innings) could hinder his chances of getting another look in the big-league rotation in 2025.

The Pirates optioned Harrington to Triple-A Indianapolis following Friday's game against the Rockies.

EDGE Analysis

Harrington was called up Friday to give the Pirates depth out of the bullpen, but he was rocked for six runs on seven hits and two walks in just two-thirds of an inning. His spot on the 26-man roster will be filled by Dauri Moreta, who was recalled by the Pirates on Saturday.

The Pirates recalled Harrington from Triple-A Indianapolis on Friday.

EDGE Analysis

Harrington has surrendered nine earned runs in only eight MLB innings this season, and he carries a 5.48 ERA through 90.1 frames in Triple-A. Despite his performance, he'll be awarded a spot on the Pirates' pitching staff after Pittsburgh traded away David Bednar, Bailey Falter and Taylor Rogers on Thursday.

The Pirates optioned Harrington to Triple-A Indianapolis on Thursday.

EDGE Analysis

Called up from Triple-A on April 1 when the Pirates temporarily expanded to a six-man rotation, Harrington was lit up for six earned runs over four innings while taking a loss in his MLB debut against the Rays. He shifted back to the bullpen following that start and piggybacked Carmen Mlodzinski in Monday's win over the Cardinals, earning a four-inning save while allowing three earned runs. The Pirates still envision Harrington filling a starting role in the long term, so he'll head back to Indianapolis and will presumably re-enter the Triple-A club's rotation this weekend. He could be back with the Pirates in short order, however, as Pittsburgh will begin a stretch of 10 games in 10 days Friday and could bring Harrington aboard for a spot start during that stretch to keep ace Paul Skenes on a five-day rest schedule between starts.

Harrington allowed three runs on four hits and a walk over four innings during Monday's win over St. Louis. He struck out five and earned a save.

EDGE Analysis

Harrington entered the game with a 4-1 lead and earned his first career save in an 8-4 win despite his shaky performance. He came into the 2025 season as one of the Pirates' top prospects but has not seen great results at the MLB level yet. Harrington has given up nine runs with a 7:5 K:BB through eight innings. He won't be available in any capacity for at least a few days and it's unclear how the Pirates plan to use him moving forward.

Harrington could piggyback Carmen Mlodzinski during Monday's game against the Cardinals, Noah Hiles of the Pittsburgh Post-Gazette reports.

EDGE Analysis

Harrington has remained on the Pirates' active roster since his ill-fated major-league debut last Tuesday against the Rays, but the team hasn't revealed concrete plans for his usage. It would make sense for him to follow Mlodzinski on Monday, as Mlodzinski still isn't fully stretched out to start after spending most of the last two seasons as a reliever. Harrington yielded six runs over four innings last week versus the Rays.
