Feltner is listed as the Rockies' starting pitcher for Sunday's game against the Phillies.
Feltner was expected to make just one turn through the rotation after he was called up from Triple-A Albuquerque last weekend, but he'll end up drawing a second start after Chi Chi Gonzalez (oblique) was moved to the injured list Wednesday. The right-hander didn't inspire much confidence in his MLB debut against Atlanta, working only 2.2 innings while giving up six runs on five hits -- including three home runs -- and two walks in a losing effort.
