Seattle’s ‘mystery pitcher’ has been revealed, but it’s not a starter as initially reported. Instead, the Mariners have signed right-handed reliever Carl Edwards Jr. The 28-year-old won a World Series title with the Chicago Cubs in 2016 and was worth 1.2 fWAR in the last full season he pitched. The Mariners will have Edwards under club control through the 2022 season.
Last season was an absolute disaster for Edwards; injuries limited him to just 17 innings pitched all year, and in those 17 innings he greatly struggled with some legit command issues. Edwards was traded to the Padres at the trade deadline this past July and wound up on the Injured List just two weeks later.
