Chamberlain owns a 4.09 ERA in 22 innings on the year, but there were some suggestions that he may have been a bit unlucky in Detroit. Opposing hitters own a .360 BABIP against him, as well as a 21.7% HR/FB rate. While solid contact could explain those marks, Chamberlain’s fastball velocity is in line with his career numbers and he’s struck out 6.1 batters per nine while walked just 2.0.
Toronto has long been looking for ways to bolster its bullpen, and will at the very least pick up some depth in Chamberlain. It’s far from clear that the signing will keep the team out of the market for relief arms, but perhaps it reduces the need for the club to deal for a serviceable veteran in addition to whatever else it might get done.
