Crosby’s three RBIs help A’s end five-game losing streak to Giants in Bay Bridge Series

A’s end five-game skid to Giants

OAKLAND, Calif. — Bobby Crosby drove in three runs, rookie Trevor Cahill won his third straight decision and the Oakland Athletics ended a five-game losing streak in the Bay Bridge Series with a 5-1 victory over the San Francisco Giants on Monday night.

Travis Ishikawa hit a solo home run in the second to put San Francisco ahead but that’s all the offense the Giants could muster. Orlando Cabrera doubled in a run in the fourth for Oakland to tie the game at 1, then Ryan Sweeney’s RBI groundout two batters later gave the A’s the lead.

Crosby hit a two-run double in the sixth and had an eighth-inning RBI groundout in Oakland’s third win in four games.

Cahill (5-5) allowed four hits in seven innings, struck out four and walked one in his 15th start of the year, most by an AL rookie. He retired the final seven batters he faced and has allowed only four earned runs in his last 19 1-3 innings over his last three starts.

Reliever Brad Ziegler pitched two perfect innings with a career-best four strikeouts for his sixth save in seven chances.

The Giants had outscored Oakland 27-4 during the five straight wins dating to last season. The A’s managed just three total runs to get swept in San Francisco from June 12-14 — the first Giants’ sweep since June 2001. That series is still plenty fresh for both franchises.

Struggling San Francisco starter Jonathan Sanchez (2-9) lost his fourth straight outing and is winless in five starts since a victory against Atlanta on May 25. The left-hander has a 7.22 ERA since that win, allowing 19 earned runs in 23 2-3 innings. It hasn’t helped that the Giants have scored one or fewer runs in nine of his 13 starts.

Sanchez has gone six innings only twice this year.

His bosses discussed skipping his turn but opted to give him another outing to try to work things out.

“This is a big start for him,” manager Bruce Bochy said before the game. “It’s important he shows a little more consistency and gets us deeper in the game.”

The Giants didn’t have to go far to kick off a 10-game, 11-day road trip — just right across San Francisco Bay.

Giants infielder Juan Uribe was scratched because his injured left hamstring was still bothering him. He was hurt June 13 and has been limited to a pair of pinch-hit appearances since. Edgar Renteria played in his place.

He also tripled. … Oakland DH/1B Jason Giambi got the day off to rest his sore body. … The “Moneyball” movie focused on the 2002 A’s and GM Billy Beane’s innovative management style has been put on hold. … Rookie A’s pitcher Josh Outman had an MRI exam on his injured left arm but the results weren’t immediately known. He left Friday night’s game against the San Diego Padres in the second inning with tightness in his pitching arm. … A’s minor league OF Larry Cobb was suspended 50 games after testing positive for a performance-enhancing drug. … Crosby had been in a 5-for-43 funk before the double.
