Josh Collmenter will start Wednesday against the Astros. Diamondbacks manager Kirk Gibson said improvement is needed with his fastball command next time out. Collmenter has been in a free fall recently. The unorthodox right-hander had a couple nice starts in July, but he's been mostly terrible since mid-June, allowing at least five runs in five of nine outings. Avoid him in fantasy until he proves he can turn things around; that is, unless you're in a deeper NL-only league and want to take the chance on a great matchup against the punch less Astros on Wednesday.
