CHICAGO -- Derek Holland's second rehab outing as he recovers from offseason surgery on his left knee didn't go quite as smooth as his first one did.
Pitching for Triple-A Round Rock on Monday, Holland allowed four runs in just one inning against Memphis. He gave up four hits, walked one and struck out three. He was supposed to go three innings and 50 pitches but did not come out for the second inning after throwing 42 pitches.
"I just had bad fastball command," Holland said. "Everything else was working great. I couldn't command my fastball the way I wanted to. I got behind in counts, and then they got some good pitches to hit when I was behind in the count.
"The knee feels good. There's no pain or anything like that. It feels strong. The only thing I'm upset about is me not being able to command my fastball, because I'm better than that. At the same time, I've got to realize that I am coming off a knee surgery, and I'm making adjustments to hitters in real games."
Holland will likely start again on Saturday, this time for Double-A Frisco. He pitched two scoreless innings for them in his first rehab start, last Wednesday.
