The Dodgers' plan of a formidable lefty-righty combination between Clayton Kershaw and Zack Greinke will apparently have to wait.

Slowed by elbow soreness for much of the spring, Greinke was bumped from the No. 2 spot in the rotation and is scheduled to make his team debut in Los Angeles' fourth game of the season Friday against Pittsburgh, MLB.com reports.

Greinke needed more time to prepare after not pitching in a spring game for nearly four weeks. He has made just three appearances overall, registering a 7.88 ERA with five strikeouts and four walks.
