The Mariners announced that they have traded left-hander Anthony Misiewicz to the Royals for cash considerations. The lefty had been designated for assignment yesterday.
Misiewicz, 27, seemed to have a nice breakout during the 2020 season, throwing 20 innings out of Seattle’s bullpen during that shortened campaign with a 4.05 ERA, with a 28% ground ball rate, solid 7.2% walk rate and excellent 30.1% strikeout rate. Unfortunately, he couldn’t quite carry that over into the following seasons, as his ERA shot up to 4.61 in both 2021 and here in 2022. His strikeout rate fell to 22.5% last year and dropped even further to 14% here in 2022. He got optioned to Triple-A in June and has fared better in a small sample of 12 1/3 innings, logging a 3.65 ERA, 23.6% strikeout rate, 10.9% walk rate and 51.5% ground ball rate.
For the Royals, they will add a controllable reliever to their lefty bullpen depth chart. Misiewicz came into the season with exactly two years of MLB service time and won’t be able to cross the three-year mark this year due to his having already spent about six weeks in the minors. They can keep him in the minors and see if he can get into a good groove. Amir Garrett is currently the only southpaw in the big league club’s bullpen, meaning there’s a path for Misiewicz to earn his way back onto the roster.
