The Rangers announced Tuesday that they’ve released right-hander Tyson Ross in order to clear a spot on the roster for Willie Calhoun, whose previously reported promotion to the Majors has now been formally announced. The Rangers also activated Adrian Beltre from the 10-day DL, though Evan Grant of the Dallas Morning News tweets that he’s not yet ready to play. Calhoun is in the Rangers lineup tonight, playing left field and batting seventh in his MLB debut.

Ross, 30, was non-tendered by the Padres last offseason after shoulder troubles limited him to just one appearance in 2016. The right-hander spent much of the season attempting to rehab but was unable to get back to a big league mound after experiencing multiple setbacks. Ultimately, Ross was found to have the difficult-to-diagnosis thoracic outlet syndrome; he ultimately underwent surgery to alleviate the issue in October.

Texas signed both Ross and Andrew Cashner to one-year deals this past offseason, hoping that the pair of former Padres teammates could eventually solidify the final two spots in a contending rotation behind the likes of Yu Darvish, Cole Hamels and Martin Perez. Ross made his way back to the Majors early in the summer, right around the team’s projected timeline, but he’s looked like a shell of his former self through 49 innings in a Rangers uniform. In that time, Ross has more walks (37) than strikeouts (36), which has been the primary reason for his unsightly 7.71 earned run average.

The struggles of Ross and injuries elsewhere on the roster led the Texas front office to make the difficult decision to trade Darvish with just seconds to go as the non-waiver trade deadline loomed on July 31. That trade netted the Rangers Calhoun (in addition to minor leaguers A.J. Alexy and Brendon Davis), and Calhoun will now join a team that has somewhat improbably hung around the Wild Card race after trading away its ace back on July 31.
