ANAHEIM, Calif. (AP) _ Ben Grieve had three hits, including a solo homer and a go-ahead single in a four-run ninth inning as the Oakland Athletics beat the Anaheim Angels 7-4 Wednesday night.

Grieve, batting in the cleanup spot for the second night in a row and second time of his career, singled off Mark Petkovsek (2-2) for a 4-3 lead after a single by Ryan Christenson, a sacrifice by Randy Velarde and an intentional walk.

Jeremy Giambi followed a walk to Matt Stairs with a two-run single, making it 6-3, and Eric Chavez added an RBI single for a four-run lead.

The Athletics rallied after their shaky bullpen allowed two runs to tie it 3-3 in the eighth.

Oakland rookie Mark Mulder allowed one run on five hits in 7 2-3 innings. After he left in the eighth with Oakland leading 3-1, two outs and a runner on first, Tim Salmon greeted reliever T.J. Mathews with an RBI double, narrowing the gap to one.

Jason Isringhausen replaced Mathews, and Garret Anderson doubled to score Salmon. The blown save was Isringhausen's third in nine chances this year and the fourth by Oakland's bullpen in the last eight games.

Isringhausen (2-2) still got the win, pitching 1 1-3 innings.

Mulder, who lowered his ERA to 4.83, has four no-decisions since winning his big league debut in an 8-5 victory over Cleveland on April 18, his only decision so far.

The 22-year-old left-hander, the second player taken in the 1998 draft, struck out six and walked one against the Angels.

Miguel Tejada's two-run single off Kent Bottenfield gave Oakland a 2-0 lead in the second. Grieve, who has 21 RBIs in his last 14 games, homered against Bottenfield in the third to stake Oakland to a 3-0 lead.

Darin Erstad's leadoff homer in the third, his fifth, gave the Angels their only run off Mulder. Erstad had three hits, including an RBI single in the ninth, to raise his average to .385.

Mulder got out of a jam in the fourth after the umpires ruled that a fan touched an apparent run-scoring double by Troy Glaus that short-hopped the low fence in the left-field corner.

Anderson, who led off with a single, came home on Glaus' hit. But he was sent back to third by second-base umpire and crew chief Al Clark after all four umps huddled and ruled it a ground-rule double.

Replays appeared to show a fan leaned over the fence and reached for the ball, but did not touch it.

Edgard Clemente, the next batter, grounded to third, and Anderson was tagged out in a rundown. Matt Walbeck followed with a single, with Glaus holding at third, and Trent Durrington grounded into a double play with the bases loaded to end the inning.

Moments later, Anaheim batting coach Mickey Hatcher was ejected by Clark for yelling from the dugout about the ground-rule double. Hatcher charged onto the field toward Clark, but Anaheim first baseman Mo Vaughn restrained the coach with a bear hug, eventually wrestling him to the ground.

Bottenfield allowed three runs on eight hits in 6 2-3 innings. Often going deep into the count, he threw 132 pitches, struck out six and walked four.

Notes: Oakland center fielder Terrence Long was scratched from the lineup after being hit in the mouth by a thrown ball during batting practice. The injury was not believed to be serious. Christenson replaced Long in center and in the leadoff spot. ... The Angels optioned struggling rookie right-hander Ramon Ortiz to Triple-A Edmonton and recalled Jarrod Washburn from the Trappers. Ortiz was 2-2 with a 6.90 ERA in six starts with Anaheim. ... Anaheim manager Mike Scioscia said he expects right-hander Ken Hill, placed on the 15-day DL after straining a rib cage muscle pitching Tuesday, to be sidelined for more than the two weeks.
