Royals dethroned

SURPRISE, Ariz. (AP) -- Kansas City closer Jeremy Affeldt left with a strained left groin in the Royals' 2-1 loss to San Francisco.

Affeldt faced only two batters before leaving in the fourth inning with a 3-1 count on Pedro Feliz.

"It's not that serious," Royals manager Tony Pena said. "We don't want to take any chances. I did not hesitate to take him out."

Affeldt, who had 13 saves in 17 opportunities last season, has been hindered by blisters and a torn oblique muscle in his first three seasons in the majors.

The Royals also played without first baseman Mike Sweeney, who missed his second straight game with a sore right oblique.

The Giants scored their two runs in the first inning off Ryan Jensen (0-1). Tony Torcato doubled home Deivi Cruz with the first run and Feliz singled to left to score Torcato.

Emil Brown homered in the eighth off Armando Almanza for the only Royals' run. Brown, who has two home runs in seven at-bats, is trying to wedge his way into a crowded outfield.

"He's taking the opportunity we have given him," Pena said. "We'll keep playing him more and more."

Left-hander Noah Lowry pitched 3 2-3 scoreless innings, allowing three hits and striking out five to pick up the victory.
