"[On Friday], I felt great at the plate and had nothing to show for it," said the Cubs outfielder, who is batting .135. "I'm working with [hitting coach Rudy Jaramillo] every day. It's just getting them to fall where they aren't."
In Houston on Tuesday, Colvin was 2-for-4 with his second home run. He felt good then, too.
"I just have to go up there and keep battling and know it'll turn around," said Colvin, who batted .254 last season, his first in the big leagues. "It definitely can't get any worse. It's not hurting my morale any -- I know I can hit. I'm just starting slower than I'd like."
Cubs manager Mike Quade said Colvin may be pressing.
"His discipline hasn't been as good, and often times that happens when you start pressing," Quade said. "It's human nature to struggle some, and instead of being more patient you wind up being more aggressive and fighting to get out of it. ... He'll be fine, but he has to be disciplined and get pitches to hit, and when he does that, he's so talented, he'll be fine."
Colvin has tweaked his swing and dropped a leg kick that he had been using as a timing mechanism. He's felt better since losing that.
And that sophomore jinx?
"I don't believe in that stuff," Colvin said. "Either I can hit or I can't, and I know I can hit, and I will."
