The Rangers selected Bradford's contract from Triple-A Round Rock on Monday, Evan Grant of The Dallas Morning News reports.
Bradford will start Monday against Atlanta in his MLB debut after posting a 0.91 ERA, 0.86 WHIP and 37:13 K:BB over 39.2 innings with Round Rock this season. The left-hander is worth keeping an eye on, but he'll be a risky streaming option against a strong Atlanta offense.
