OAKLAND, Calif. -- That talented, young pitching rotation the Athletics are banking on to carry them this season is holding down its end of the deal so far.
Brett Anderson struck out eight and outdueled usual Oakland nemesis John Lackey for his first victory of the season, and the A's beat Boston 5-0 on Tuesday night to snap the Red Sox's three-game winning streak.
David DeJesus got Oakland on the board with a first-inning RBI groundout, then Hideki Matsui added a two-run double and Daric Barton and Kurt Suzuki each hit RBI singles in a four-run eighth. Anderson (1-1) allowed four hits and walked one in eight innings, helping the A's (9-8) move over .500 for first time this year.
A's starters have allowed just one earned run over their last five games -- spanning 33 2/3 innings -- for a 0.27 ERA.
"It's fun when we're going good like that," Anderson said. "We want to feed off each other and keep putting up zeros."
The Red Sox were coming off a 9-1 win over the Blue Jays, highlighted by 13 hits and three home runs. Boston remains winless away from Fenway Park -- the 0-7 road start is the worst in franchise history -- and was blanked for the second time this season after losing 1-0 at Cleveland on April 7.
"We'll be all right," second baseman Dustin Pedroia said. "We might be the first team to lose our first seven on the road and win the next seven, who knows."
Red Sox manager Terry Francona was ejected for the first time this year for arguing a play on the basepaths in the fourth.
Anderson looked sharp all night and improved to 4-1 with a 2.08 ERA in six career starts against the Red Sox. The starters are on a nice roll.
"Every one of them has a solid routine between starts and they are ready to pitch," manager Bob Geren said.
Boston had a chance against Anderson in the eighth after David Ortiz led off with a single and was lifted for pinch-runner Jacoby Ellsbury. But Mike Cameron struck out and Ellsbury was caught stealing for a double play. Initially, interference was called on Cameron but crew chief Tim Welke cleared things up afterward. Even Ellsbury thought the call was batter interference.
In the seventh, Anderson tripped on the front of the mound and committed Oakland's majors-leading 19th error while making a throw to first after fielding Adrian Gonzalez's comebacker. But Anderson got Kevin Youkilis to ground into an inning-ending double play.
After Gonzalez's two-out single in the first, Anderson didn't allow another hit until Ortiz's single. The burly left-hander retired 16 of 17 batters during one stretch with only a leadoff walk to Pedroia in the fourth.
Pedroia was caught stealing moments later and Francona was ejected by plate umpire Jim Reynolds for arguing. Francona claimed it was an obvious balk.
Lackey (1-2) allowed four hits in six innings, struck out three and walked one in his best start so far. The right-hander threw two side sessions under the guidance of first-year Red Sox pitching coach Curt Young during a long layoff between starts. He was supposed to pitch last Wednesday but the game against Tampa Bay was rained out and he had his turn skipped.
"Never been skipped before. It was not fun," Lackey said. "Just trying to locate the fastball better. It was something I didn't do well the first two starts. I thought I did well tonight. You've got to get out there and throw bullets."
Lackey -- 17-6 with a 2.86 ERA against the A's in 32 career starts, most of those coming during his days with the AL West rival Angels -- lowered his ERA from 15.58 ERA to 9.82 after struggling through his first two outings of 2011.
"Watching him pitch tonight, you can't really see how he struggled early in the year," Geren said. "That was vintage John Lackey."
But Boston couldn't generate much offense in the opener of a quick, two-game visit to the Coliseum -- one of only two West Coast trips for the Red Sox this season. They came to Oakland twice in 2010 and also played in San Francisco for interleague. The A's go to Fenway Park for a pair of three-game series.
After this stop, the Red Sox head to Southern California to play four games with the Los Angeles Angels before three games at Baltimore. They don't come back West until August at Seattle.
Francona stuck with the hot hand of shortstop Jed Lowrie, who entered batting .516 with two home runs and nine RBIs. Lowrie went 0 for 4 with two strikeouts and had his seven-game hitting streak snapped. Francona said he is communicating with Marco Scutaro and is writing the lineup based on performance.
Francona was ejected for the 30th time as a manager. ... A's LHP Dallas Braden, placed on the 15-day disabled list Monday with a shoulder injury that forced him out of his Saturday start early, is scheduled to be examined by renowned orthopedist Dr. Lewis Yocum on Wednesday in Los Angeles. RHP Tyson Ross will start in Braden's spot Friday at Seattle. ... Oakland RHP reliever Michael Wuertz (strained left hamstring) is set to pitch in a rehab outing for Triple-A Sacramento at Reno on Wednesday -- going four or five outs. ... Young returned to Oakland for the first time since spending the past seven seasons coaching the A's pitchers.
