SEATTLE -- Eric Chavez hit a three-run homer and Mark Mulder worked six strong innings, leading the Oakland Athletics over the Seattle Mariners 8-2 Thursday.
It didn't take long for the A's to get to work and earn a split of the four-game series.
Mark Kotsay led off the game with a double to the right-field corner, Eric Byrnes singled to right and Chavez drove a 1-2 pitch from Jamie Moyer over the wall in right.
Jermaine Dye added a single as Moyer (1-2) gave up four straight hits to start the day.
Mulder (2-1) had quite a safety net with Oakland's 13-hit attack. He allowed two runs and five hits, then turned it over to Chris Hammond in the seventh.
It was the first time in four starts that Mulder didn't go seven innings.
Oakland stretched the lead to 4-0 in the third when Chavez scored on Erubiel Durazo's single to right. Ichiro Suzuki fielded the ball and threw home to catcher Dan Wilson, and plate umpire Terry Craft was about to signal an out when the ball rolled loose.
It was that kind of day for the Mariners, who were booed by the hometown crowd.
The Mariners gave up a run in the seventh when Randy Winn bobbled a single to center field by Damian Miller, bringing Eric Karros in to make it 6-2. Karros had a leadoff double after Winn lost the ball in the sun.
The A's stretched the lead to 8-2 in the eighth. Dye hit an RBI single and scored when Marco Scutaro grounded to first baseman Willie Bloomquist, who was charged with a fielding error on the play.
Seattle trimmed the deficit to 4-2 in the fourth. Scott Spiezio led off with a single, Raul Ibanez also singled and Rich Aurilia walked.
Spiezio scored on Wilson's sacrifice fly and Ibanez crossed the plate when Jolbert Cabrera hit a slow groundout to second.
That was all the offense Seattle could generate, though, and Moyer ran into more problems in the fifth.
The A's made it 5-2 after Chavez drew a leadoff walk, went to third on Dye's single and scored on Karros' sacrifice fly. Chavez scored three times.
When Moyer walked the next batter, Durazo, manager Bob Melvin sprung from the dugout and signaled for reliever Julio Mateo.
Moyer went 4 1-3 innings, allowing five runs on seven hits. After winning 21 games last year, the fifth pitcher to win at least 20 after age 40, Moyer has a 9.00 ERA in his two losses and a no-decision.
