Contreras, who underwent surgery after suffering a season-ending Achilles' injury Aug. 8, was 3-0 with a 5.82 ERA in 17 innings. Colon (0-2, 6.60) hasn't pitched a full season since winning 21 games and the AL Cy Young Award in 2005 because of shoulder, elbow and oblique muscle injuries. He had surgery to remove bone chips in the offseason.

"These guys are basically finishing their third week of spring training," pitching coach Don Cooper said. "It was important for us to get their pitches up, and we did that with both guys. On top of that, we got command and performance. It's nice when everything you kind of hope to happen happens.

"They've been climbing. There are reasonable expectations for us to say that they can continue to climb, both in stuff and command."

Manager Ozzie Guillen hasn't yet determined the order of his rotation, other than Buehrle being the opening-day starter.

"I want to check out the matchups when we get to Chicago (on Sunday)," Guillen said. "That way, I'll have a better idea. I want to see who they are going to face if they go '4' and '5.' No matter who is '4' or' 5,' I really don't care. You are No. 1 when you are on the mound. ... The way they threw made a lot of people in this locker room very excited."

Diamondbacks starter Jon Garland gave up one run in four innings in his final spring tuneup, giving up four hits and walking four.

"It's probably the best I've felt all spring," Garland said, "and I'm not just saying that because we're at the end. My mechanics felt real good. A walk every inning, to me that's not acceptable. I'm a contact pitcher. I need to get it over the plate and put it in play."

Chicago's Carlos Quentin doubled off Garland to open the third inning and scored on a two-out single by shortstop Alexei Ramirez.

Brent Lillibridge, acquired in the Javier Vazquez deal with Atlanta in the offseason, doubled, stole third and scored on a sacrifice fly in the fifth. Lillibridge made the White Sox as a reserve infielder and outfielder.

Notes: Arizona finalized its 25-man roster by purchasing the contract of infielder/outfielder Ryan Roberts, who made the team as a non-roster invitee by hitting .280 with two home runs and 10 RBIs. He also caught in spring training and will serve as the emergency catcher. ... The White Sox reassigned catcher Donny Lucy to minor league camp and purchased the contracts of catcher Corky Miller and reliever Mike MacDougal after the game, giving Miller and MacDougal spots on the opening day roster. The White Sox's 40-man roster stands at 39. ... Diamondbacks outfielder Justin Upton was hit by pickoff throws from Colon in the back and in the right leg after singling with two outs in the eighth.
