Alejandro De Aza opened the Chicago White Sox scoring in the fifth inning and scored the go-ahead run two innings later to give the White Sox a 3-2 lead.
With the score tied, 2-2, De Aza christened the seventh inning by reaching base on reliever Yusmeiro Petit's throwing error. De Aza stole second base and sped home on Tyler Flowers' single.
The Giants began the scoring with a pair of first-inning runs off White Sox starter Felipe Paulino. Gregor Blanco singled and scored on Michael Morse's double. Buster Posey collected his fifth RBI in two games with a bloop single to right field that sent Morse home.
Giants starter Tim Lincecum blanked the White Sox on one hit through four innings before Chicago pulled even. Dayan Viciedo doubled leading off the fifth, and scored on De Aza's single. After Flowers' single advanced De Aza to third base, Leury Garcia's bunt single off reliever Dan Runzler delivered the tying run. Adam Eaton's single loaded the bases, but Runzler slipped called third strikes past Gordon Beckham and Jose Abreu to end the threat.
Up next: Ryan Vogelsong is scheduled to oppose the Texas Rangers on Thursday in the Giants' first night game of the spring, airing live on MLB.TV and Gameday Audio at 6:05 p.m. PT. Vogelsong will strive to rebound from a rough outing against Seattle last Sunday, when he yielded seven runs (five earned) in 2 1/3 innings. Vogelsong, the Giants' projected No. 5 starter, surrendered a pair of two-run homers in the first inning. In two outings before that, he allowed only one run and four hits in five innings while walking none.
