The Tigers announced Monday that they’ve designated right-hander Devin Sweet for assignment. His spot on the 40-man roster will go to newly extended top prospect Colt Keith, who inked a six-year deal with three club options over the weekend.
Detroit only claimed Sweet off waivers 11 days ago — marking his fourth organization in four months. He’s gone from Seattle to Oakland to San Francisco and Detroit via waivers, and the Tigers will now have a week to either trade Sweet or place him on outright waivers yet again. If he clears, the Tigers could retain him as Triple-A depth, but the sheer volume of teams who’ve put in a claim on Sweet suggest there’s a chance he could yet again be claimed.
The 27-year-old Sweet surrendered 10 runs in 8 2/3 innings for the Mariners during this past season’s MLB debut. His minor league track record is far more impressive. In 44 innings between the Double-A and Triple-A levels this past season, the formerly undrafted free agent notched a pristine 2.25 ERA with a 32.6% strikeout rate and 6.3% walk rate. Sweet isn’t a flamethrower — he averaged 93 mph on his heater with Seattle — but has consistently missed bats and avoided walks as a professional. In five minor league seasons, he’s whiffed 29% of his opponents against a 7% walk rate. He has a pair of minor league options remaining, too, which will certainly appeal to other teams looking for some flexible bullpen depth in the late stages of the offseason.
