Zych gave up the Mariners' only run, albeit unearned, in Tuesday's victory over Houston.
After Tuesday's performance, Zych's ERA sits at 3.27 and he has brought his K/9 to an incredible 13.09. Despite his ability to strike out batters, Zych has a 1.36 WHIP on the year, as he frequently walks the opponent. If he can learn to control his pitch location more effectively, his ERA should fall, for Zych has only given up seven hits this season.
