Rockies hoping to solve Bumgarner

Rockies hoping to solve Bumgarner

Colorado will get its second look of the season at Giants ace Madison Bumgarner on Saturday in a matchup against Eddie Butler.

The Rockies tagged Bumgarner early in his May 6 start, scoring four runs (two earned) in the second inning, although they ended up losing the game, 6-4, as the Colorado bats fell silent for the rest of the game.

Bumgarner has been effective despite a drop in velocity by over a full mile per hour on his fastball. He is currently sixth among qualified pitchers with a 2.17 ERA and 10th with 10.45 strikeouts per nine innings. He's been especially effective during May, featuring a 0.98 ERA and 0.93 WHIP over five starts.

Things to know about this game

• Despite playing on division rivals, few Rockies have seen Bumgarner many times. DJ LeMahieu (3-for-26) and Nolan Arenado (6-for-28) have struggled against the lefty, while Carlos Gonzales (11-for-36) has hit better than his career .290 average against Bumgarner.

• Butler had perhaps the best start of his career against the Giants on May 8, pitching six shutout innings with a career-high six strikeouts, while allowing four hits and two walks.

• Going into Friday, the Rockies had allowed the fewest home runs (12) in May. The Giants had allowed the second-fewest (19).
