Kansas City, Mo. ? John Buck lined a game-winning single with the bases loaded in the 11th inning to help the Kansas City Royals complete an 8-7 comeback victory over the Chicago White Sox on Tuesday night.

Mitch Maier set up the winning run by walking with one out, then went to third on Willie Bloomquist’s hit-and-run single off Lance Broadway (0-1). Alberto Callaspo was intentionally walked, and Buck lined the next pitch just past third baseman Josh Fields.

Callaspo followed with a run-scoring double off Matt Thornton, who later walked Coco Crisp with the bases loaded to cut the White Sox’s lead to 7-6.

Floyd allowed six runs and six hits in his second shaky outing the past three starts.

Royals starter Kyle Davies wasn’t any better, giving up two homers, six runs and eight hits in four innings. Fields led off the third inning with a homer, and Dye, back after two games, hit a two-run shot three batters later to put the White Sox up 4-0.

The Royals crept back within one, but Davies gave up another run in the fourth on Carlos Quentin’s RBI single and was done after Dye’s leadoff single in the fifth. Alexei Ramirez followed with a run-scoring single off Robinson Tejeda and Podsednik made it 7-4 with a sac fly.
