"I'm going to try and do what I did in college and last year in Yakima, and that's pound the zone with strikes," said Roemer, the 50th overall selection last year out of Cal State-Fullerton.
"If I do that, I'm sure I'll move up quickly."
Roemer said he received his share of hazing during spring training, including a tongue lashing from veteran second baseman Orlando Hudson for not being ready soon enough before an exhibition.
"I learned a lot while I was up there," Roemer said. "Everyone thinks of big leaguers as being laid-back, but they work their butts off. You can't mess around or Hudson or [outfielder Eric] Byrnes are going to come up and kick your butt."
