OAKLAND, Calif. – Vladimir Guerrero made a costly throwing error that led to a five-run eighth inning, overshadowing his second consecutive two homer game as the Oakland Athletics beat the Los Angeles Angels 8-4 on Friday night.

Guerrero hit a game-tying two-run homer in the sixth and added a go-ahead shot in the eighth. But the A’s came back in the eighth to win for the third time in four games.

Mike Piazza singled off Scot Shields (3-4) with one out in the eighth. After Mark Ellis flew out, Marco Scutaro singled down the right-field line.

With pinch-runner J.J. Furmaniak seeming to round third, Guerrero hesitated between throwing to third and home. He double clutched and threw home, but short-hopped cutoff man Robb Quinlan. The ball bounced loose up the third-base line, allowing Furmaniak to score and Scutaro to reach second. Dan Johnson followed with a double, snapping an 0-for-17 streak, to score the go-ahead run.

After Shields hit Kurt Suzuki with a pitch, Donnie Murphy singled home another run.

Greg Jones relieved Shields, and Travis Buck greeted him with a two-run double to make it 8-4.

Guerrero went 39 days without a home run before connecting twice on Thursday night. On Friday night, his first home run came on a 3-1 pitch from A’s starter Lenny DiNardo.

Santiago Casilla (3-1) gave up Guerrero’s second home run but got the win when the A’s rallied.

Chone Figgins went 2-for-3 with a walk to continue his torrid offensive pace as the Angels lost their second in three games. Figgins is hitting .414 (92-for-222) since June 1, tops in the majors.

Angels starter Dustin Moseley ran into trouble in the third, hitting a batter, walking another and giving up an RBI double to Mark Kotsay before clamping down and retiring nine straight, including RBI groundouts by Jack Cust and Piazza. Moseley gave up three runs and four hits in 5 1-3 innings, walking three and striking out three.

After Moseley gave up singles to Cust and Scutaro sandwiched around a walk to Piazza to load the bases with one out, Chris Bootcheck came on and got Johnson on a short fly to center. Suzuki then flied out to right to end the threat.

Guerrero hit two home runs in back-to-back games for just the second time in his career, and the first since Sept. 17-18, 2000. He’s 5-for-9 with four home runs and seven RBIs in the first two games of the series.

DiNardo lasted six innings, giving up three runs on five hits. He walked two and struck out two.

Notes: Angels C Ryan Budde made his first big league start. … The A’s have used 47 players already this season, the most in the majors and two shy of the Oakland record. … The Angels have been in first place every day since April 25. … A’s 2B Mark Ellis has not made an error in 69 straight games, one shy of the Oakland record.
