With Sonny Gray sidelined with back spasms, the Oakland A's needed to turn to their Triple-A affiliate to bring up a starter for their Friday night game against the Baltimore Orioles. Left-hander Brad Mills got the call from Triple-A Nashville. He will be making his first MLB start of the season on Friday after spending the entire 2015 season to date in Nashville.
Mills has a 4.45 ERA in 127.1 innings for the Sounds this season. Mills has struggled his last two outings, allowing 13 runs in 8.1 innings, but he had been pitching well before those outings. Mills historically has fared well against the Orioles. He has a career 8.15 ERA in the major leagues, but he made three starts for the A's last year and had a 4.41 ERA.
Mills wasn't on the A's 40-man roster, so to make room for him, Oakland designated reliever Taylor Thompson for assignment. Thompson spent most of the 2015 season on the A's 60-day disabled list after injuring his shoulder during spring training. He was recently activated off of the 60-day DL and optioned to Triple-A. He has allowed three runs in 4.1 innings for the Sounds.
To make room for Mills on the A's active 25-man roster, Oakland optioned reliever Arnold Leon to Triple-A. Assuming Gray's back issue clears up in time to allow him to make a start in the next few days, Mills' stay with Oakland could be just for one day. The A's could then option Mills back to Nashville and bring up another Sounds' reliever, possibly Dan Otero or Pat Venditte.
