To open a roster spot, the Halos designated fellow right-hander Dayan Diaz for assignment. With the move, the Marlins now have an open 40-man slot to work with.
Needless to say, this isn’t the sort of mid-summer trade acquisition the Angels envisioned making at the start of the season. Despaigne has mostly functioned as a gap-filling swingman since he reached the majors, so he isn’t the sort of pitcher who’d be targeted by a contender. Sitting 11.5 games out of postseason position, the Angels simply aren’t one. The move seems designed merely to relax the burden on the club’s injury-riddled pitching staff.
Despaigne has spent a bit of time working as a MLB long reliever this year, but has thrown more at Triple-A. Over 43 1/3 innings at the highest level of the minors, he hasn’t allowed a single home run but carries a 4.36 ERA with 8.3 K/9 and 2.5 BB/9. In his 331 major-league frames over the past five years, Despaigne has a 4.76 ERA, though estimators suggest he has been a bit better than that (4.30 FIP; 4.61 xFIP; 4.19 SIERA).
As for Diaz, who was claimed off waivers last fall from the Astros, he opened the year on the restricted list owing to visa troubles and really never got going. Though the 29-year-old reliever briefly reached the majors in 2016 and 2017, he has only made seven appearances at the High-A level this year.
