Rangers left-handers Martin Perez and Matt Harrison have each possibly thrown their last pitch of 2014.
Perez was diagnosed with a partial tear of the UCL ligament in his left elbow, which could mean Tommy John surgery. The club is considering the options, which also include a non-surgical route that could have Perez back in the rotation in 10-12 weeks.
Fellow southpaw Matt Harrison met with a back specialist in Dallas Wednesday and was diagnosed with severe nerve irritation (in the L5-S1 spondylolisthesis, according to Fox Sports) that could require a career-threatening spinal fusion surgery. He was placed on the 15-day disabled list with "lower back inflammation" Wednesday.
Perez was put on the 15-day disabled list Wednesday with left elbow inflammation. He reported discomfort in his throwing elbow after his last start Saturday against Boston. An MRI Sunday revealed the inflammation in Perez's elbow, but showed no structural damage.
The news is worse than first predicted, and the worst case scenario could be reality.
Harrison left Tuesday's start in Houston with stiffness in his back after just 1.2 innings. He threw 55 pitches in the outing before his early exit. The 28-year-old lefty made his 2014 debut on April 27 after missing almost all of 2013 due to injury. He had two surgeries to repair a herniated disc in his back, and a third surgery on his right arm.
Nick Martinez will move from the bullpen to the starting rotation to take Harrison's place.
Wednesday's roster moves
Nick Tepesch was recalled from Round Rock to make Wednesday night's start. He has gone 6-1 with a 1.58 ERA in his time with the Express this season.
The team has also recalled right-handed pitcher Miles Mikolas from Triple-A Round Rock. Mikolas will be in uniform and seeking to make his Texas debut in Wednesday's series finale in Houston.
Mikolas has a 3.38 ERA (3 ER/8.0 IP) in eight relief appearances while allowing no walks with five strikeouts with Round Rock this season. He began the year on the disabled list, and was activated April 19.
Reliever Justin Germano was designated for assignment to make room for Scott Baker, whose contract was purchased and will be on his second major league stint with Texas this season. Germano has an 11.81 ERA in two relief outings this year, including 3.1 innings Tuesday against the Astros in an 8-0 loss.
Baker made one appearance with Texas before being designated for assignment on May 11. He has not appeared in a game with Round Rock since then.
Texas has 10 days to trade, release or outright Germano to the minor leagues.
