The Cubs have selected the contract of right-hander Anthony Bass from Triple-A Iowa, clearing space on the 25-man and 40-man rosters by optioning Cory Mazzoni and transferring Eddie Butler from the 10-day DL to the 60-day DL (Twitter link via Mark Gonzales of the Chicago Tribune).
Bass, who turned 30 this offseason, has only pitched 5 2/3 innings in the Majors over the past two seasons, all coming with the Rangers last season. He spent the 2016 campaign with Japan’s Nippon Ham Fighters, working to a 3.65 ERA in 103 2/3 innings.
That said, Bass still brings a fair bit of Major League experience to the table. The right-hander has logged 284 career innings, working to a 4.60 ERA with 6.0 K/9, 3.4 BB/9 and a 47.6 percent ground-ball rate in the big leagues. He’s spent the season to date in Triple-A, pitching to a pristine 2.28 ERA with 20 strikeouts against six walks in 23 2/3 innings out of the bullpen.
Butler, meanwhile, has been out since April 20 due to a groin strain and has yet to be sent out on a minor league rehab assignment. He’s already nearing the 60-day mark on the disabled list, and being transferred over won’t reset the date on which he’s eligible to be activated. He’ll technically be eligible to activated later this month, though there’s no indication from the Cubs as to when he’ll be healthy enough to return.
