Rangers third baseman Adrian Beltre has been activated from the 15-day disabled list, effective immediately, the club has announced. As a corresponding move, Kevin Kouzmanoff -- who has been brilliant in filling in for Beltre -- was placed on the 15-day disabled list with a herniated L5-S1 disc in his lower back.

Kouzmanoff had left Tuesday's game against the A's with lower back tightness and headed back to Texas for tests on his back. Per MLB.com, Kouzmanoff may end up needing surgery.

Kouzmanoff, 32, hit .362/.412/.617 (178 OPS+) with six doubles, two homers and 10 RBI in 13 games after taking over for the injured Beltre. Still, the track records here indicate Beltre is still a net-positive moving forward over Kouzmanoff.
