Detwiler, 36, has appeared in 13 MLB seasons dating back to 2007. Last year, he pitched for both the Marlins and the Padres, logging 52 1/3 frames with a 4.64 ERA. Working with a changed pitch mix, Detwiller completely altered his profile last year. Swapping out sinkers for four-seam fastballs, he sacrificed grounders but gained strikeouts. After getting worm burners above 50% for three years in a row from 2018-2020, it dropped to 39.9 in 2021. His strikeout rate, which had been around 15% for most of his career, jumped to 27.1% last year.
Signed by the Reds to a minor league deal in April, the southpaw has thrown seven innings for the Triple-A Louisville Bats. That’s obviously a tiny sample size, but he has a 3.86 ERA with a 40% ground ball rate, 21.9% strikeout rate and 15.6% walk rate. With Justin Wilson on the IL and Phillip Diehl designated for assignment last week, the club has been without a lefty in the bullpen until they added Detwiler today.
As for Dugger, this is his third time being designated for assignment in the past couple of weeks. He was selected by the Rays at the beginning of May and given 5 1/3 innings of mop-up duty just before the roster size was set to shrink from 28 to 26. After that outing, he was put on waivers and claimed by the Reds. Cincy gave him three more innings of mop-up work, designated him again, outrighted him to Triple-A and then selected his contract two days later. This time, he’s sent back out into DFA limbo without the mop-up duty, as he still just has the two appearances on the year.
