12:45pm: The Reds announced the move, adding that lefty Justin Wilson is heading to the 10-day injured list with a soreness in his left elbow. With Wilson sidelined and Diehl up in the Majors, the Reds will still have just one lone southpaw option in the bullpen.
11:25am: The Reds are selecting the contract of left-handed reliever Phillip Diehl, reports C. Trent Rosecrans of The Athletic (Twitter link). It’ll be the Cincinnati native’s first big league work since appearing with the Rockies in 2020. The Reds have an open spot on the 40-man roster at the moment, so no corresponding 40-man move was necessary. The team hasn’t yet announced the transaction, though, so it’s possible it’ll be accompanied by other roster moves.
Diehl, 27, is in his second season with his hometown organization. He spent the 2021 season with the Reds’ Triple-A affiliate in Louisville, where he pitched to a terrific 2.47 ERA with a 33% strikeout rate against a 5.6% walk rate in 54 2/3 innings of relief. Despite that showing, Diehl didn’t get a look in the big leagues with the Reds, who claimed him off waivers from the Rockies in early April and passed him through waivers a month later.
This season, Diehl has has yielded four earned runs on five hits and a walk with 11 strikeouts through eight frames. He’ll give manager David Bell a second southpaw option in a bullpen that had previously only included veteran Justin Wilson.
In 13 1/3 career Major League innings, Diehl has allowed 13 runs. He’s been outstanding at Triple-A dating back to last season, however, and has a long history of both missing bats (31.1% strikeout rate) and limiting free passes (6.7% walk rate) in parts of six minor league seasons.
