The Cubs have made a host of roster moves today (first announced by Patrick Mooney of The Athletic), chiefly among them the placement of right-hander Anthony Bass on the 10-day disabled list due to a back muscle issue. The move creates room for the recently acquired Jesse Chavez to be activated. The club also promoted righty Dillon Maples, optioned fellow righty James Norwood, and recalled righty Luke Farrell as the 26th man for today’s double-header against the Cardinals.
Bass has been excellent across 16 appearances for the Cubs so far this season, pitching to a 2.93 ERA in 15 1/3 innings. He’s also managed an impressive ground ball rate of 53.3%. Bass spent time on the disabled list earlier this month with what was described as an illness. When he’s been healthy, though, the 30-year-old has enjoyed a career-best performance, certainly an upgrade over his 4.51 career ERA and a career K/BB ratio worse than 2:1.
Chavez, recently acquired from the Rangers, has also been quietly enjoying an excellent season, as MLBTR’s Jeff Todd noted at the time the trade was announced. Chavez will presumably see the same type of work with the Cubs as he did with the Rangers: multi-inning relief appearances. Though Chavez appeared 30 times on the mound with Texas, he managed to toss 56 innings during that time.
