OAKLAND -- Rookie Roenis Elias struck out six while pitching into the seventh to win consecutive starts for the first time, Justin Smoak drove in three runs and the Seattle Mariners beat the A's 8-3 on Tuesday night for their season-best fourth straight victory.
Smoak hit an RBI double and Dustin Ackley an RBI single in the first to back Elias (3-2), who followed up a 10-strikeout gem at Yankee Stadium his last time out with another impressive start.
The Mariners jumped on Jesse Chavez (2-1) to take a quick first-inning lead for the second straight game against the A's -- and Seattle scored all three of its first-inning runs with two outs on the way to its ninth win in 11 games overall.
Chavez got a scare and escaped injury in the fourth when he saved himself from a hard-hit liner by Michael Saunders by catching the screamer that was going right for his face.
Making the play knocked him off his feet to end the fourth, and the small Coliseum crowd of 12,106 briefly fell silent.
Chavez got a double play to face the minimum in the fifth, but his night ended after allowing Mike Zunino's sixth-inning sacrifice fly following a hit batsman and a walk.
Oakland No. 9 hitter Nick Punto pulled Oakland back in it with a two-run, two-out single in the second. Yoenis Cespedes, back in the starting lineup after nursing a left hamstring injury, hit a leadoff home run in the sixth. The A's squandered a scoring chance in the seventh against Dominic Leone, leaving the tying run on third as they again struggled with runners in scoring position.
Elias allowed three runs and five hits with three walks in 6 1-3 innings in his seventh career start.
Sean Doolittle struck out all four batters he faced in relief of Chavez. But Seattle added on four unearned runs in the top of the ninth against 2013 AL saves leader Jim Johnson, who was booed off the mound when pulled by manager Bob Melvin as fans headed for the exits. Smoak added a two-run single.
Neither manager had announced his starters for Wednesday's doubleheader, though Felix Hernandez will pitch one of the games for Seattle and likely Erasmo Ramirez the other.
Oakland will make right-hander Arnold Leon its 26th player for the second game but is likely to start Drew Pomeranz since he didn't pitch in relief Tuesday. The 25-year-old Leon's family was scheduled to fly in from Mexico for his likely major league debut after nine seasons in the minors.
The teams are playing two after an April 4 game was called because of a soggy field that had mistakenly gone without its tarp during a heavy rainstorm.
NOTES: Saunders, who came in batting .393 with a homer and five RBIS in seven games batting leadoff, went 0 for 4 atop the order. "I don't like messing with success," manager Lloyd McClendon said. "He's been doing great, we've been doing great. It's kind of hard to change that."... A's reliever Eric O'Flaherty, on the disabled list since undergoing Tommy John surgery in the offseason, threw a 30-pitch bullpen session and could begin throwing to hitters soon, and Melvin said an announcement on the pitcher's next step would come Wednesday. ... Melvin said Triple-A catcher Stephen Vogt, an A's playoff star last October currently on Sacramento's disabled list, is close to returning from a strained oblique muscle.NEXT GAMES A’s vs. Mariners WHEN: Today, Game 1, 12:35 p.m.; Game 2, approximately 30 minutes after first game ends WHERE: O.co Coliseum TV: CSN California RADIO: KGMZ (95.7 FM)
