PITTSBURGH -- It has been tough for Tyler Chatwood to wait for his next start after an abbreviated game on Sunday night, but the right-hander said he had a good bullpen session on Tuesday, made a few adjustments and was looking forward to his next outing on Friday against the Mets.
"It was good," Chatwood said on Tuesday. "I've been doing this for eight years now, so it was just a matter of feeling good, and I felt good today in my side. Now, it's just a matter of taking it into the game."
Chatwood, who leads the Major Leagues in walks with 45 over 48 1/3 innings, said he did make a couple of changes and is trying to get the ball out of his glove earlier and shorten his stride. Doing those things helped him stay on top of the ball, Chatwood said.
But the problem isn't just a matter of mechanics, according to the right-hander.
"I think when you start walking people and you have to answer questions after the game, it might creep into your mind a little bit," Chatwood said. "For me, I feel one of my strengths is my competitiveness and mental toughness. I don't feel it's getting magnified. I just have to clean it up, I know that."
Chatwood has lasted 2 2/3 innings in each of his last two starts.
"The worst part is the bullpen has to eat those innings," Chatwood said. "To come out early, you don't feel good. Those four days [between starts] are probably the longest four days you'll have in a while."
Top prospect hurt
Adbert Alzolay struck out three over four scoreless innings for Triple-A Iowa on Tuesday but was lifted after 60 pitches because of a grade one (least severe) lat strain. He'll be re-evaluated in a few days. Alzolay did not give up a hit or walk a batter.
"That's a special human being right there," Cubs catcher Chris Gimenez said. "Tremendous young man, very personable kid. He works his tail off. I think we can see the arm is electric. Now, it's just a little more of a consistency, just cleaning up some things mechanically."

Skype session
Cubs manager Joe Maddon talked to students at Whitney M. Young Magnet High School in Chicago via Skype on Tuesday, answering questions and revealing his favorite ice cream flavor is chocolate chip but he can't eat it because he discovered he's lactose intolerant.

There was also an awkward moment when Maddon learned that the teacher was a White Sox fan.
