UNDATED (AP) — The World Series resumes tonight in San Francisco after Wednesday night's 7-2 win by the Royals. That victory evened up the best-of-seven series after the Giants won the opening game Tuesday night. Game 2 was tied at 2-2 before the Royals exploded for five runs in the sixth inning.

Giants right-hander Tim Lincecum (LIHN'-sih-kuhm) was sent for an MRI of his tight back to determine whether he can remain on the active roster when the World Series resumes at AT&T Park.

The two-time NL Cy Young Award winner was walked off the field by athletic trainer Dave Groeschner during the eighth inning of San Francisco's 7-2 loss in Game 2 when his left lower back tightened. Lincecum retired five straight before exiting during Salvador Perez's at-bat.

The pitching matchup for Game 3 has Tim Hudson scheduled to start for the Giants against Jeremy Guthrie.

If neither team sweeps the three games in San Francisco, the series will shift back to Kansas City for Game 6 next Tuesday.

ATLANTA (AP) — Former Cleveland and Texas general manager John Hart has been named president of baseball operations by the Atlanta Braves. He had been hired by the club as interim general manager on Sept. 22 and will also continue to serve in that role. It's unclear if Hart's new title means the team no longer will seek a full-time replacement for Frank Wren, the former general manager.

The club has announced that the 66-year-old Hart has agreed to a three-year contract that will continue through the team's first season at its new stadium in Cobb County.
