Texas Rangers outfielder Evan Carter is not expected to play again this year, according to general manager Chris Young.
Carter has not played since May 26 with what the Rangers called lower back tightness.
The 21-year-old was a breakout star for the club last postseason en route to a World Series victory.
Carter made his Major League debut on Sept. 8, and slashed .306/.413/.645 in 23 games to help Texas secure a wild-card berth. In the playoffs, he hit .300/.417/.500 in 17 games.
