Harris, 27, struck out three in 1 2/3 innings for Colorado Springs on Friday and wasn't expected to land in San Francisco until gametime on Saturday, so it was unlikely that he would be used. After piling up 66 strikeouts to 13 walks in 66 games, including 20 strikeouts and one walk at Triple-A, the former LSU pitcher has a chance to show Rockies manager Jim Tracy what he can do.
"What I hear about him is so encouraging. ... He has pounded the strike zone with a lot of energy -- he will not back off," Tracy said. "I was very intrigued when I heard about the command and the way he has aggressively attacked the strike zone. I like to hear about stuff like that. The opportunity is here for us to find out a little bit more information."
