HOUSTON — The Rockies' starting rotation has been a revolving door of late.
Right-hander Eddie Butler was sent down to the Triple-A Albuquerque Isotopes to work on his command and fine-tune his offspeed pitches. That gave right-hander David Hale and lefty Chris Rusin a chance to impress.
But Rusin has stumbled in his last two starts, with home runs being his Achilles' heel.
He gave up six runs on 11 hits — including two home runs — in 5 innings in Colorado's 6-0 loss at Miami on Friday. In Tuesday's 8-5 loss to the Houston Astros, he lasted four innings, giving up seven runs on nine hits, two of those homers.
