The Colorado Rockies and the Miami Marlins clash on Sunday afternoon to determine a series split for the former or a series victory for the latter. It will be a pitching duel between the Rockies' Drew Pomeranz and the Marlins' Josh Johnson.

Pomeranz (1-7, 5.04 ERA) won his only game of the season back on July 6, a dominant 6.1-inning performance against the Washington Nationals. He's gone 0-4 in six starts since then, most recently losing to the San Francisco Giants. He allowed four runs in four innings in the 9-3 loss.

Johnson (7-9, 3.73 ERA) enters this contest on a two-game losing streak, but his offense has failed to provide him much run support. He took the loss in 6-1 and a 1-0 decisions. In the latter contest, Johnson pitched eight innings, allowed three hits and struck out seven.

First pitch is scheduled for 1:10 p.m. MT. ROOT Sports and 850 KOA will have coverage.
