Back from Double-A Tulsa and looking to lock down a rotation spot, Rockies starter Drew Pomeranz didn't put his best foot forward Monday against Miami.

With the Marlins being unable to score against anyone in the second half of the season, it was not impressive that Pomeranz allowed three earned runs on five hits and four walks over just 4 1/3 innings in a loss. He dropped to 0-4 on the year with an ugly 8.10 ERA. He struck out two and threw 78 pitches.

Pomeranz, who has been working on adding a slider to his pitching arsenal, continues to struggle. For now, he's scheduled to make his next start Saturday against Milwaukee.
