MINNEAPOLIS -- Texas purchased left-hander Michael Roth's contract from Triple-A Round Rock and transferred Colby Lewis to the 60-day disabled list, the Rangers announced before Sunday's game at Minnesota.
Rangers manager Jeff Banister said the 26-year-old Roth, who last pitched in the majors in 2014 for the Los Angeles Angels, would be in the bullpen for Sunday's game. Transferring Lewis, who was originally placed on the 15-day DL last month with a strained latissimus dorsi, allowed the Rangers to make room for Roth on the major league roster.
To make room on the active roster, the Rangers optioned right-hander Luke Jackson to Double-A Frisco.
The moves came a day after Texas allowed 17 runs against the Twins. The Rangers were forced to their bullpen early, as starter Chi Chi Gonzalez recorded just two outs in his second start of the season.
"We needed a little bit of length today," Banister said.
Reliever Trevor May, who has missed 21 games on the DL with back spasms, was also back in the clubhouse. Manager Paul Molitor said May wouldn't be activated Sunday because he was coming off pitching in back-to-back games in his rehab assignment.
