Samardzija sets down 15 straight in Giants' 3-1 win over A's

SAN FRANCISCO (AP) Jeff Samardzija retired 15 consecutive batters after allowing a triple on his third pitch of the game, and the San Francisco Giants beat the Oakland Athletics 3-1 on Thursday night.

Buster Posey had three hits, including an RBI double in the fifth. Brandon Crawford and Ehire Adrianza also drove in runs for San Francisco, and all three runs scored with two outs.

Samardzija was sharp in his final tuneup of the spring while working five crisp innings. He struck out five, didn't walk anyone and allowed only three balls out of the infield over his final four innings. Samardzija has allowed only two runs over his last 11 innings and hasn't walked a batter since March 16.

Stephen Vogt doubled in Billy Butler in the seventh for Oakland's only run. The A's have lost four straight.
