Kluber (back) allowed just one hit over five shutout innings in a rehab start Friday for Double-A Akron, Brad Bournival of the Cleveland Plain-Dealer reports.

EDGE Analysis

Kluber retired the final 13 batters he faced and needed just 47 pitches to complete five frames. He was so efficient that he needed to head to the bullpen to throw more pitches to ensure he is stretched out by the time he reports to the major league club. Kluber could return as soon as May 31 against Oakland.
