Profar had been attempting to come back from a shoulder injury that caused him to miss the entire 2014 season. He had been throwing from 105 feet without discomfort, the team said, but an MRI on Tuesday showed damage in his throwing shoulder. Profar has been undergoing MRI exams every three weeks to monitor his progress.
The MRI indicated an issue with Profar's subscapularis muscle in his right shoulder, but the surgery will be for a torn labrum, which is believed to be the root cause of Profar's recurring shoulder problems, according to Anthony Andro of FOX Sports Southwest.
Though the team said a timeline for Profar's return would not be available before the surgery is performed, Jeff Wilson of the Fort Worth Star-Telegram reports Profar's season is likely over.
Profar, who turns 22 on Friday, was the consensus top prospect in baseball before the 2013 season. The Rangers called him up in May of 2013 and he played 84 games at second base, shortstop, third base and leftfield. He batted .234 with a .336 slugging percentage that season.
Profar was shut down during spring training last year when the shoulder issue flared up. He was expected to return at some point midseason but suffered a setback in May and missed the rest of the year.
Profar's injury opened the door for rookie Rougned Odor to start at second for the Rangers last season. He batted .259 with a .402 slugging percentage in 114 games.
