SURPRISE, Ariz. -- C.J. Wilson is the Rangers' Opening Day pitcher. Phil Humber is just trying to make the White Sox pitching staff.

Humber perhaps was pitching with greater urgency and he held the Rangers scoreless over three innings before the White Sox rallied for a 7-6 victory at Surprise Stadium on Thursday. Wilson was almost as good, allowing one run in his four innings of work.

Humber could be the White Sox fifth starter if Jake Peavy isn't ready to start the season or he could be a long man in the bullpen. In either case, he advanced his cause by holding the Rangers to two singles in three innings. He retired nine of 11 hitters faced while throwing just 26 pitches, 19 for strikes.

"If you are a [long-relief] guy, they want you to attack the hitters and see what happens," Humber said. "If you go out there and walk guys, they can't use you. I definitely want to attack the zone."

Wilson threw 59 pitches over his four innings as he gave up three hits, walked one and struck out three. Wilson has now pitched nine innings this spring and allowed six runs (five earned) on 11 hits, three walks and five strikeouts.

"It was warm out there," Wilson said. "It was great. Warming up in the bullpen with the sunshine and heat, it made it feel like Texas today."

David Bush followed Wilson to the mound and gave up a two-run home run to Mark Teahen, who had three hits, in the sixth that gave the White Sox a 3-0 lead. Rangers left fielder Craig Gentry crashed through an open gate in the fence while tracking Teahen's blast but escaped unharmed.

Mike Napoli's two-run double highlighted a five-run sixth inning as the Rangers rallied to take the lead against White Sox reliever Brandon Hynick. Josh Hamilton, Nelson Cruz and Kevin Cash also drove in runs in the frame.

Chicago's Michael Restovich knotted the score at 6 in the ninth inning with a two-run single off the Rangers' Mark Lowe. Andrew Garcia followed with a game-winning RBI triple.
