De La Rosa (0-2) couldn't get out of the fifth inning in Wednesday's start against the Dodgers, giving up three runs (two earned) on five hits and a walk in 4.2 frames. He struck out three.
The erratic righty has opened ugly this year, having tossed only nine innings between two starts and a relief appearance. De La Rosa has great raw stuff, but harnessing it has been a continuous challenge for him and it's starting to look like only a matter of time until he gets demoted into a bullpen role, where his fastball-slider repertoire seemingly would play much better than it does in the rotation. If any promising pitcher starts banging on the door in the minors, De La Rosa seems the likeliest Arizona starter to be displaced.
