SEATTLE -- Ryon Healy ripped an RBI double in the top of the ninth off Mariners closer Edwin Diaz to give the A's a 4-3 win Saturday night at Safeco Field.
Healy drove in Rajai Davis for the winning run after Davis beat out an infield single and stole second. Diaz intentionally walked All-Star first baseman Yonder Alonso to face Healy, but the A's designated hitter drove an 0-2 slider into the right-center gap for a ground-rule double.
• Davis' speed a factor in win
"That's something they had to do, but certainly gives you more going to the plate, and he's an emotional guy, so it's just about harnessing it and focus and put a good swing on it" A's manager Bob Melvin said Healy after the intentional walk. "You look at his numbers and it doesn't surprise you when he comes up with a hit like that."

Diaz fell to 2-4 with a 3.83 ERA with the loss and the 23-year-old closer has allowed eight hits and seven runs (three earned) over five innings in his last five outings.
"He had an 0-2 count and made a mistake," Seattle manager Scott Servais said. "He left the ball right in the middle of the plate. And in this league, the middle lineup guys are going to make you pay. You hate to focus all on one pitch, but unfortunately when you're in the ninth inning in a tie game, it does come down to one pitch."
Chris Smith became the oldest first-time starter in A's history at age 36, but wound up with a no-decision after giving up six hits and three runs in six innings.

"I thought he pitched great," Melvin said. "That's not the easiest of lineups, and actually some of those guys have faced him before, too. I was hoping to get him into the sixth today, and he gave us six and allowed us to go to the three guys we go to [in the bullpen] in tie-or-win games. So he did his job and probably a little bit more. It was fun to see."
Alonso hit his 20th homer of the year in the third for the A's and Marcus Semien gave the A's a 3-2 lead when he just cleared the fence in left field for his fourth home run of the season in the fifth, before Seattle tied the game back up with a homer by Jarrod Dyson.
Dyson went 2-for-3 and scored twice and shortstop Jean Segura had a pair of doubles and an RBI in a 2-for-4 night that puts his average at .355.

Andrew Moore allowed three runs over six innings on six hits in his third career start for the Mariners, turning a 3-3 tie over to the bullpen, but Seattle wound up losing for the ninth time in its past 12 games in falling to 42-47. Oakland (39-49) has won four of its last five.

MOMENTS THAT MATTERED
Little big man: Dyson is known for his speed, but the Mariners' 5-foot-10, 160-pound center fielder tied the game at 3 with his fifth home run of the season leading off the fifth. Dyson, who also doubled and scored in the third, drove a 2-1 fastball from Smith into the right-center-field seats to continue an unlikely power surge. Dyson totaled seven home runs in seven previous seasons in Kansas City.
Vincent the magnificent: The A's threatened in the top of the eighth against reliever Nick Vincent when Jed Lowrie singled with one out and Bruce Maxwell walked. But after falling behind 3-1, Vincent struck out Matt Chapman, then did the same to pinch-hitter Khris Davis after trailing 2-0 in the count. Vincent has been outstanding as a setup man for Seattle all year and remains unscored on in 19 innings over 20 appearances at Safeco, the fifth-longest streak in franchise history for a reliever in a single season.
"They threw some tough at-bats against him, but Nick has a way of making pitches deep in counts and executing," Servais said. "I think that's the difference between a veteran pitcher and kind of where Diaz is at right now."

QUOTABLE
"I saw snowmen up there. So that's good. I hope my wife got a picture." -- Smith, on hitting 88 mph during Saturday's game
"The inconsistency of our club. Some nights we can look like world beaters and get real excited and the offense is clicking and we're playing good defense. Other nights, not so good. " -- Servais on what has stood out the past two weeks from his Mariners
SOUND SMART WITH YOUR FRIENDS
Moore was 18 1/3  innings and 70 batters into his career before walking his first batter when he issued a free pass to Maxwell with one out in the fourth. And then Moore promptly walked the next batter as well (Chapman). Those were his only walks in his six innings of work.
WHAT'S NEXT
Athletics:Daniel Gossett (1-3, 6.23 ERA) takes the hill for the final game before the All-Star break in a 1:10 p.m. PT Sunday start. The rookie righty has made five of his six Major League starts in day games since being called up June 14.
Mariners:Felix Hernandez (3-3, 5.04 ERA) closes out the first half in Sunday's 1:10 p.m. PT game against the A's. The veteran right-hander makes his fourth start after a two-month stint on the disabled list with shoulder bursitis and faces a familiar foe, as he's 23-9 with a 2.68 ERA in 44 career outings against Oakland.
