Santiago feels ready to work out of bullpen

MILWAUKEE -- Hector Santiago was pleased with his three perfect innings to start Friday night's game against the Brewers.

Santiago said he struggled early this spring, but has found his rhythm and is ready for the season to start. He struck out five of the nine batters he faced.

"Those first two weeks were rough, trying to find the arm slot and get back to it," he said Saturday. "Then the last four, five, maybe six days actually finding it and kind of putting all the work and all that stuff I figured out in the end right there, all into one. I went out there and just threw it."

Santiago started for the White Sox Friday night, but will pitch out of the bullpen during the regular season.

"Yesterday just kind of felt like everything was there," he said. "Everything was out of the same spot.

"I want to kind of just stay prepared and do the same thing in the bullpen," he said.

Looking healthy, Crain earns spot on roster

MILWAUKEE -- White Sox manager Robin Ventura made it official Saturday morning -- Jesse Crain has made the Opening Day roster.

Crain reported no ill effects on Saturday from his 11-pitch outing on Friday night, an appearance where he threw nine strikes and looked like the effective right-hander he was last season.

"Everything's good, so he made the team," Ventura said before the White Sox closed Spring Training with a game against the Brewers at Miller Park. "That's a big hurdle for us as far as making the decision on him. He's available for Monday."

Crain missed much of Spring Training with a strained right abductor and had pitched tentatively in three outings in Arizona. He looked much better against Milwaukee on Friday.

"He looked like you would think as far as his effort and velocity and all that," Ventura said. "It was a comforting inning to watch him pitch."

Crain was 2-3 with a 2.44 ERA in 51 relief appearances last season.

Worth noting

• The White Sox set their Opening Day roster after Saturday's game vs. the White Sox by optioning right-handed pitcher Brian Omogrosso to Charlotte, and reassigning right-handed pitchers Ramon Troncoso and Jeff Gray, infielders Steve Tolleson and Josh Bell and Catcher Bryan Anderson to their minor-league camp.
