OAKLAND -- The homer-happy A's were at it again Saturday, belting two in the first inning in support of right-hander Jharel Cotton in a 4-3 series-clinching victory over Seattle for their fifth consecutive win.
"It's a nice little run for us, and everyone is contributing," A's manager Bob Melvin said. "That's what we talked about on Opening Day, that it takes all 25 of us to win, and today is a prime example of that, that it's not just your key guys sometimes. Over the course of 162 games, some other guys have to take over in big situations."
Cotton surrendered a first-inning homer to Robinson Cano, but the A's got the run back quickly when Adam Rosales opened the bottom half of the frame with his second career leadoff home run. Jed Lowrie followed with a base hit, setting the stage for Ryon Healy's two-run blast off Seattle starter Ariel Miranda.

"It was awesome to answer back and get us on the board, and then Ryon comes up with a huge hit, and our pitching was outstanding today," Rosales said. "I think all of us look forward to getting back to the field right now. We can't wait to get to the field. We know we're going to pick each other up. That's just exciting."
• De Jong tosses four scoreless in relief
The A's lead the Majors in home runs at home, with 19 through 12 games within the typically pitcher-friendly confines of the Coliseum.
Miranda made it through just three-plus innings, allowing four runs and seven hits in the loss, as Seattle fell to 1-9 on the road. Cotton managed to hold Seattle to two runs in six innings, stranding six base runners in his second win of the season.

"We're not a team that is supposed to lose this many games," said Cano, who went 3-for-4 and scored twice. "We need to play better on the road. But that's baseball. You're not going to do it all the time. Sometimes you do it on the road, sometimes you do it at home. We just have to keep fighting."
MOMENTS THAT MATTERED
Caught in the act: The A's entered the day as one of just three teams without a catcher throwing out an attempted base stealer. That changed in the third inning, when Josh Phegley nailed speedy leadoff man Jarrod Dyson at second base for the first out. It proved significant, too, as Cotton hit Mitch Haniger to put one runner -- instead of two -- on base for Cano, who delivered a single. Nelson Cruz's sacrifice fly netted the Mariners their only run in the frame. It broke a string of 16 straight stolen bases for Dyson, dating back to last year.
"Jarrod tried to delay," said Mariners manager Scott Servais. "Cotton was quick to the plate, so he kind of took a couple shuffles and delayed steal and hoped to catch them off guard. Obviously it didn't work."
"That was big," Cotton said. "I was talking to Yonder [Alonso] in Spring Training, and he told me, 'Dude, just pick off until he gets tired. Pick, pick, pick.' And I did it three times, then he went and we got him out. It worked. Thanks, Yonder."

Sigh of relief: The Mariners staged a comeback attempt in the eighth inning but only came up with one run, when pinch-hitter Kyle Seager delivered a two-out RBI triple off the right-center field wall against righty Liam Hendriks. That prompted A's manager Bob Melvin to ask for a four-out save from right-hander Ryan Madson, who induced an inning-ending groundball from Guillermo Heredia before locking down the save -- his first of the season -- in the ninth.
"We had some guys down today, so as we've talked about, it's the next person's job to step up, and when you have a guy like Ryan Madson, who was a good closer last year, you're going to try to use him as much as you can," Melvin said. "I didn't want to have to use him for four outs, but we did. All in all, it shows the depth of the bullpen on a day our three key guys [Santiago Casilla, Sean Doolittle and Ryan Dull] aren't available."
QUOTABLE
"One of these days we will line up the pitching with the hitting. It is bound to happen. It's baseball. Just right now it's not really going our way." - Servais, after his team fell to 7-12.
SOUND SMART WITH YOUR FRIENDS
Mariners rookie right fielder Haniger was hit by a pitch and scored in the third and doubled in the fifth. He's now reached base in 23 straight games, tied for the current MLB lead with the Yankees' Jacoby Ellsbury.

UNDER REVIEW
The A's won their first replay challenge of the season in the eighth inning, successfully challenging the initial ruling that Trevor Plouffe was out at first base on the back end of a double play. Even after the call was overturned and Plouffe was deemed safe, the Mariners beckoned for their own review of Khris Davis' slide at second base on the same play. Upon review, it was confirmed Davis did not violate the slide rule.
WHAT'S NEXT
Mariners: Veteran right-hander Yovani Gallardo (0-1, 6.19 ERA) will be looking for his first win in four starts for the Mariners in Sunday's 1:05 p.m. PT series finale, but he'll need to reverse a tough career trend as he's 0-5 with a 5.29 ERA in six previous meetings with the A's.
Athletics: Right-hander Andrew Triggs, who has yet to allow an earned run in 17 2/3 innings this season, will be on the mound for the A's at the Coliseum.
