KANSAS CITY, Mo. (AP) — Madison Bumgarner was on top of his game, James Shields was not, and the San Francisco Giants cruised to an easy victory over the Royals in Game 1 of the "wild card" World Series in Kansas City.

Bumgarner was superb as the Giants earned a 7-1 victory, holding the Royals to a run and three hits with five strikeouts in seven innings. The Giants ace was working on a two-hit shutout until Salvador Perez homered with two out in the bottom of the seventh. Before the blast, the Giants already had forged a 7-0 lead.

San Francisco got all the runs it needed during the first inning off Shields as Pablo Sandoval hit an RBI double before scoring on Hunter Pence's two-run homer. Pence was 2-for-3 with two runs scored.

The Giants added two runs in the fourth before Joe Panik laced an RBI triple off Danny Duffy and came home on Sandoval's run-scoring single in the seventh.

Gregor Blanco padded the Giants' 10-hit attack by going 1-for-3 with a bases-loaded walk and two runs scored.

It was a short evening for Shields, who was tagged for five runs and seven hits in three-plus innings. Although his nickname is "Big Game James," Shields is 3-5 with a 5.74 ERA in 53 1/3 innings over 10 career postseason starts.

PHILADELPHIA (AP) — The Philadelphia Phillies have re-signed right-hander Jerome Williams to a one-year, $2.5 million contract. Williams was 4-2 with a 2.83 ERA in nine starts for the Phillies after being claimed off waivers from the Texas Rangers in August. He also pitched for Houston last year and was 6-7 with a 4.77 ERA in 37 games with all three teams.
