Kumar Rocker News: Promoted for Sunday's start

The Rangers recalled Rocker from Triple-A Round Rock in advance of his start Sunday against the White Sox.

The right-hander will step into Texas' rotation Sunday with Tyler Mahle (shoulder) landing on the injured list in a corresponding transaction. Rocker has yet to find his footing through six major-league starts this season with an 8.87 ERA, 1.84 WHIP and 21:7 K:BB over 23.1 innings, but he'll have a favorable matchup Sunday to potentially get on track.
