OAKLAND -- After kicking off a nine-game homestand on Friday night with another victory, A’s outfielder Mark Canha said the team needs to “ride the wave” as long as it can. That wave is quickly rising to heights that have not been seen around these parts in years.

The A’s continued their best stretch of the season on Saturday with a 6-5 win over the Mariners. They pushed their season-high winning streak to eight games, marking their first eight-game win streak since April 3-12, 2013, when they won nine in a row.

“We’re confident and everything is clicking right now,” A’s center fielder Ramon Laureano said. “Just keep it rolling.”

It’s no coincidence the streak has come at a time when the A’s have seen their power return, and that trend continued on Saturday when Matt Chapman got the A’s on the board early with a solo shot to right-center off Mariners starter Yusei Kikuchi in the first. It was Chapman’s 12th homer of the year, tying Khris Davis for the team lead, and Oakland’s 25th homer in its last 11 games.

Making that power surge all the more impressive is that it has come during a time in which top slugger Davis had been dealing with an injury before he was officially placed on the injured list before Friday’s win over Seattle. The contributions by the offense, which has outscored opponents 63-to-25 over the win streak, have come up and down the order.

“We have enough guys to hold the fort down,” A’s manager Bob Melvin said. “With Canha swinging the bat like he is and Olson back, we have enough. Next man up. We have enough guys to do some good things offensively and still score a bunch of runs.”

Though the offense has been on a tear over the streak, the starting pitching has also been doing its part with consistency. Mike Fiers kept that up with another quality start as he allowed three runs over six innings, pushing the combined ERA by A’s starters over the last nine games to 2.32.

Fiers has allowed three runs or fewer in each of his past six starts, a far cry from his first six starts, where he built up an 8.28 ERA as he struggled to pitch deep into games. Now he’s looking more like the pitcher who anchored the A’s rotation during their run to the playoffs in 2018.

“I still feel like I’m working on a couple of things here and there but I’m getting back to the pitcher I am,” said Fiers, who surrendered two solo home runs. “Throwing more strikes and challenging guys early, being the aggressor. Not walking guys. Making them earn their way on. Today I gave up a couple of solo homers, but most of the time, that’s not going to beat you. As long as nobody is on base, it’s not too bad.”

Getting ahead in the count was key for Fiers on Saturday. Of his 89 pitches, only 13 came when he was behind in the count.

“He was workman-like. Made a couple of bad pitches and paid for it but he gives us six innings and leaves with the lead. He’s been doing a lot of that lately,” Melvin said. “We’re not going to overdo it and run him out there 115 pitches. But anytime a pitcher throws six innings and leaves with the lead, he’s doing his job.”

Treinen escapes jam

After loading the bases to bring the potential tying run to the plate in the ninth inning of Friday’s 6-2 win, A’s closer Blake Treinen created another jam for himself on Saturday as a home run surrendered to Domingo Santana and an RBI double allowed to J.P. Crawford shrunk the lead to just one run.

“If I did, I probably wouldn’t tell you, as far as pitch complement goes,” Melvin said when asked if he’s noticed anything different from Treinen over the past couple of games. “It’s just so rare to see him get hit a little bit that I think everyone is in shock when it happens. His stuff is still good. I think he’ll be fine.”

Treinen ultimately shut the door for his 10th save of the year, but not without some help from left fielder Robbie Grossman, who made a sensational sliding catch for the second out of the inning.

With a run already in for the Mariners and Kyle Seager having just doubled, Grossman hustled over to the Coliseum’s spacious foul ground in left for the sliding catch at a sprint speed of 29.2 feet per second, which is above his season average of 27.2. Grossman covered 108 feet in 5.2 second to make the play, which only had a 15 percent catch probability, according to Statcast.

Miggy flashbacks

Laureano doubled for a fifth straight game on Saturday, becoming the first A’s player to do so since Miguel Tejada in 2003. His 2-for-3 day extended his hitting streak to a career-high eight games, though his biggest moment at the plate may have been his sacrifice fly in the eighth to give the A’s their decisive sixth run.

“He’s swinging the bat great and feeling confident,” Melvin said. “I think we’re about ready to see him start to heat up.”
