SAN FRANCISCO — The San Francisco Giants needed every available player on their roster to stay unbeaten in what turned into a marathon home opener.

Barry Zito, set to make his next start Monday against Pittsburgh, was manager Bruce Bochy's next option to pitch.

Aaron Rowand drove in the winning run with two outs in the 13th inning with an infield single, salvaging the Giants' season debut in their waterfront ballpark and keeping alive their unbeaten start with a 5-4 victory over the Atlanta Braves yesterday.

"We're just trying to keep it rolling — 4-0 is not too bad," Rowand said. "It definitely gives you some momentum, some confidence."

It was the fifth game-ending hit of Rowand's career and scored Juan Uribe, who drew a one-out walk from Kris Medlen (0-1) before stealing second. Uribe went to third on catcher Brian McCann's throwing error, and Rowand brought him home.

Edgar Renteria hit a tying two-run homer off Braves closer Billy Wagner with one out in the ninth. Atlanta manager Bobby Cox was ejected in the top of the 13th for arguing balls and strikes, the 154th ejection of his career.
