"For my first at-bats in a long time, it's the best I've ever felt in Spring Training," said Olt, who faced right-hander Neil Ramirez. "I'm not even counting last year, but the year before that. I saw the ball really well."
Acquired from the Rangers in the Matt Garza deal, Olt batted .213 at Triple-A Round Rock last season, but the Cubs feel they've corrected his vision issues. He's now taking allergy medication, which has helped clear things up for him.
Wednesday was his first test against a pitcher.
"I got in the box and I wasn't sure if I was going to swing or not, but I got in there and felt comfortable and saw the ball really well, took a couple swings and I feel like I'm ahead of schedule," he said.
