OAKLAND -- Matt Joyce homered on the first pitch Masahiro Tanaka threw, and the A's didn't let up on the Yankees' starter, going deep three times and handing the American League East leaders their fifth straight loss with a 5-2 win Saturday afternoon at the Coliseum.
Ryon Healy added the other two homers off Tanaka, who lasted only four innings. He allowed five runs on eight hits, though he struck out 10.
Jesse Hahn labored through five innings but earned the win, with only a two-run second against him. He gave up three hits and three walks while striking out six on 105 pitches.
The A's bullpen finished the day strong behind Hahn, only allowing two baserunners.
"It was awesome to see the way we pieced it together today and have each guy come in and kind of feed off the guy's performance before," Sean Doolittle said after picking up his second save of the year. "There's a lot of confidence for us down there for the first three games."
MOMENTS THAT MATTERED Avoiding early trouble: Hahn found himself in a tight situation in the first after issuing back-to-back walks with one out. But the right-hander buckled down, striking out Starlin Castro looking and getting Didi Gregorius to ground out back to the mound. He used 31 pitches in the inning, but was able to escape with no damage done.
"At the end of the day, we got the win," Hahn said. "Great team win, so I feel great about that. On my part, I think I can be a little bit more efficient there, to keep my pitch count down so I can go a little deeper in that ballgame. But everything worked out in our favor."
A's add on in the 4th: After Healy's leadoff homer in the fourth, the A's tacked on two more runs thanks to three consecutive two-out singles. Adam Rosales drove in Matt Chapman on a single to right, and Jed Lowrie beat out an infield single to score Joyce.
"The three home runs, that's unacceptable. The two to Healy, I just wasn't able to execute my pitches, it just went into that spot where he likes it the most. That's obviously unacceptable, also. But I felt like I was able to get a couple of strikeouts, which tells you that there's some bite to the offspeed stuff, so I look at that as a positive from today's outing." -- Tanaka
"We've had a chance to win every game. This game was probably the one we weren't the closest to, but we had some opportunities in this game, and we made their starter work really, really hard. … These guys are handling [adversity] well and they're continuing to fight every day." -- Yankees manager Joe Girardi, on handling the losing streak

The A's will look to finish off a four-game sweep Sunday and get some revenge for last season. When the Yankees came to Oakland for a four-game series in May 2016, they took all four games, outscoring the A's 22-9.
WHAT'S NEXT Yankees: Right-hander Luis Cessa (0-0, 5.40 ERA) will make his first career start in Sunday's finale at the Coliseum. He was called up Thursday when CC Sabathia (right hamstring strain) was placed on the disabled list. For Triple-A Scranton/Wilkes-Barre, Cessa had a 3-6 record with a 4.15 ERA in 65 innings. First pitch is set for 4:05 p.m. ET.
A's: Right-hander Jharel Cotton seeks his first win since May 4 in Sunday's series finale against the Yankees. Cotton has a 7.76 home ERA, the highest mark for any pitcher with more than 25 innings pitched. First pitch is set for 1:05 p.m. PT.
