Pittsburgh Pirates

Braxton Ashcraft

SP

Ashcraft opened with three scoreless frames but stumbled late, departing with a 3-0 deficit at just 67 pitches. The 26-year-old has now yielded three earned runs or fewer in seven straight outings, but he's exceeded 90 pitches just once in that span and appears to be having his workload limited down the stretch. He owns a 3.65 ERA, 1.09 WHIP and 173:35 K:BB across 165.1 innings this season and lines up for a road matchup with the Cubs next weekend.

Isaac Mattson

RP

The right-hander has been shuttled between Triple-A and the majors throughout the season and is now getting another look with the Pirates. Mattson has pitched in 37 MLB games this season and has a 4.91 ERA, 1.58 WHIP and 34:18 K:BB over 36.2 innings.

Ryan O'Hearn

RF

O'Hearn has not played in a game since he went down with a left quad strain in late July, but he's been cleared to test things out at the Pirates' top minor-league affiliate. The 31-year-old is aiming to be reinstated to the active roster ahead of this weekend's series at Wrigley Field against the Cubs.

Kirby Yates

RP

Yates hasn't pitched since Saturday, so it could be an injury that's nagged at him for a while. The veteran reliever will be eligible for activation Sept. 15, though it's unclear at this point if he will be ready to go on that date. Khristian Curtis is grabbing Yates's roster spot.

Endy Rodriguez

C

The transaction clears space on the 40-man roster for the addition of Christian Bethancourt. Rodriguez underwent season-ending surgery last week to repair the labrum in his left hip.

Mitch Keller

SP

Keller's move to the IL comes just one day after he was lit up for seven earned runs on six hits and four walks in just two innings during Sunday's 10-2 loss to the Reds. The Pirates haven't provided an official recovery timeline for Keller, but his move to the 60-day IL makes him ineligible to be activated until Oct. 2, and the regular season concludes Sept. 27. The Pirates recalled Brandon Eisert from Triple-A Indianapolis to join the roster as a replacement for Keller, who ends his eighth MLB season with a 6-8 record, 5.29 ERA, 1.37 WHIP and 89:42 K:BB over 115.2 innings.
