SAN FRANCISCO – Scott Kazmir pitched two-hit ball into the sixth inning, Josh Reddick hit a two-run homer and the Oakland Athletics beat the San Francisco Giants 4-0 on Thursday night.

Josh Donaldson doubled, tripled and drove in two runs for the A's, who had dropped five of seven before knocking around Giants starter Tim Hudson.

Reddick's third home run this spring came on the first pitch he saw in the sixth and ricocheted off one of the flag poles behind the seats in right field. A Gold Glove winner in 2012, Reddick also made a nice play to chase down Pablo Sandoval's deep fly to right-center in the sixth.

Hudson was roughed up for the third time in his last four outings, allowing four runs and six hits over six innings. Five days after a stellar start against the Chicago White Sox, the right-hander walked one and struck out six.
