Mark DeRosa hits sharp single in San Francisco Giants debut

Giants’ DeRosa looks good in first spring outing

SCOTTSDALE, Ariz. — One pitch, one swing and Mark DeRosa showed the kind of threat he can be for San Francisco’s offense.

DeRosa lined a sharp single over shortstop Omar Vizquel’s head in his debut at-bat after being limited following October wrist surgery, and the Giants beat the Chicago White Sox 6-2 on Tuesday.

Fred Lewis and Buster Posey hit consecutive homers in the eighth for San Francisco. Lewis’ drive was a two-run shot.

The game was delayed an hour by heavy rain in the desert.

White Sox starter John Danks struck out four over three scoreless innings. He hasn’t given up a run in his five spring innings.
