The Dodgers optioned Wrobleski to Triple-A Oklahoma City on Monday, Jack Harris of the Los Angeles Times reports.
Wrobleski was pummeled for 10 runs over 5.1 frames in a start Sunday in Arizona. He was filling the rotation spot vacated by Clayton Kershaw (toe), and it's not clear what the Dodgers plan to do the next time Kershaw's spot comes up. They could summon another spot starter or perhaps go to a five-man rotation for one turn.
