OAKLAND, Calif. -- Nobody in the Oakland clubhouse could remember the Athletics' last lopsided win.
They beat Tampa Bay by five runs on April 10, but every victory since had been a challenge until the A's routed the World Series champions Wednesday.
Eric Chavez hit a three-run homer, David Wells flopped in his first start in three weeks and the A's defeated the Boston Red Sox 13-6 to win the three-game series. Oakland had dropped its previous four series since taking two of three from Seattle from April 29-May 1.
"It's been a while since we've done that," Chavez said of the slugfest. "We've had a lack of production at the plate, and now we're starting to swing the bats better."
Seth Etherton (1-0), called up from Triple-A Sacramento on Sunday to make his first major league appearance since 2003, pitched 7 1/3 strong innings a day before his wife was scheduled to deliver their first child -- and an Oakland starting pitcher got plenty of run support for a change.
The right-hander retired 15 of the first 17 Boston batters, allowing a leadoff homer to Jason Varitek in the third. Mark Bellhorn hit a solo shot of his own to start the sixth for the Red Sox, who have lost three of four and four of six.
The A's batted around in the first two innings. By then, every starter but Keith Ginter had a hit, though he had contributed a sacrifice fly and a walk.
Eric Byrnes had four hits and scored three runs, and Jason Kendall, Scott Hatteberg and Mark Ellis each had three of Oakland's 19 hits. Mark Kotsay had a two-run double and Chavez drove in four runs as Oakland established season highs for hits and runs.
"I don't remember the last time we coasted to a win like this," said Byrnes, batting .550 (11-for-20) during his current five-game hitting streak. "This feels great."
The A's reached double figures in runs for the first time all year -- they were the only team in the majors that hadn't scored 10 or more in a game.
This is a whirlwind week for Etherton, who hadn't pitched in the majors since losing a start for Cincinnati on Sept. 17, 2003, at Pittsburgh.
After the game, he was headed straight to the airport to return home to Laguna Beach, Calif., where his wife, Summer, will be induced Thursday ahead of her May 24 due date. Their son will be named Duke Michael -- after Duke Snider -- and the team is letting Etherton stay home until Sunday.
"It's a big week," Etherton said. "Now it's time to get nervous."
Etherton retired his first six batters on 22 pitches before allowing Varitek's eighth homer. His 7 1/3 innings matched his career high and he received a warm ovation when he left after allowing three straight baserunners.
"Maybe he'll hit the lottery," manager Ken Macha said. "Things happen in threes, don't they?"
The A's quickly staked Etherton to a 4-0 lead, welcoming back Wells (2-4) with six hits in the left-hander's 26-pitch first inning. Wells was done after 1 1/3 innings, his shortest outing since June 8, 2001, with the Chicago White Sox when he faced five Cubs batters without getting an out.
"I didn't come close to helping out today," Wells said. "It's one of those days you want to find a hole and crawl in it. But I'll be back out there. ... A bad day is a bad day, and there's nothing you can do about it."
The A's tagged Wells for seven runs and nine hits in his sixth start of the year and first since April 25 because of a sprained right foot.
Kotsay tested Wells right away, bunting for a leadoff single. Byrnes and Kendall followed with singles to load the bases. Chavez drove in a run on a fielder's choice, and Ginter hit a sacrifice fly.
Hatteberg followed with an RBI double off the wall in right-center, then Erubiel Durazo singled in a run to make it 4-0. By the end of the second, Etherton had a 9-0 lead.
Chavez homered in the second for his second in two days, fourth of the year and No. 167 of his career, tying him with Rickey Henderson for sixth place in Oakland history.
When Chavez is hitting, it seems to affect the entire offense.
"That was nice," Ellis said. "It was good to finally break out and score some runs. Wells is a good pitcher. We had a lot of two-out hits."
