Logan pitched for Triple-A Colorado Springs in New Orleans on Thursday and Friday, and he appeared sharp in both outings, striking out the only batter he faced on three pitches Friday. He was placed on the disabled list with left elbow inflammation on March 28, retroactive to March 21.
"It went good," Logan said of his Minor League tune-up. "I pitched the last two days, I went back to back. An inning the first day, and then yesterday was one hitter, situational. I'm feeling pretty good. I'm looking forward to competing."
It was the first time Logan had pitched in back to back games this spring, and the Rockies are likely to be cautious, giving him a couple of days off before adding him to the roster for the White Sox series that starts Monday.
"I'm a little sore, but it's normal sore," Logan said.
Weiss did not express concern over what he called "typical soreness that pitchers have the day after they pitch," and he confirmed that Monday was the most likely return date.
"That was a good test for him," Weiss said of Logan's past two outings. "It went real well. We'll try to be smart about getting him back in there."
