OAKLAND -- The A’s don’t expect one specific player to pick up the load in the absence of Khris Davis, but Mark Canha is currently doing his best impression of the prolific slugger.

Filling in the designated hitter role on the day the A’s learned Davis will require a stint on the 10-day injured list with a left hip/oblique contusion, Canha continued his impressive power tear in Friday’s 6-2 win over the Mariners, extending Oakland’s season-high winning streak to seven games.

• Box score

Canha’s solo shot off Mariners starter Wade LeBlanc was his eighth of the season and third in as many games. He’s now homered six times over his past nine games, reminiscent of the many home run barrages Davis has put together over the years as MLB’s home run king since the start of the 2016 season.

“I guess you could say it’s timely,” Canha said. “I’m filling his shoes. I’m trying to be Davis right now, and this is my best version of it. It always helps when you have that one guy where you’re like, ‘Yeah! He’s up.’ That happens to be me right now.”

LeBlanc was the latest left-hander to be victimized by Canha. Since the start of the '18 season, Canha has now homered 16 times against lefties, trailing only Davis and Joey Gallo for most home runs off left-handed pitchers among American League hitters over that time.

The A’s have seen what Canha can do at the plate with consistent playing time. Adjustments have a higher likelihood of paying off when you're one or two at-bats every couple of days turn into an everyday role. Canha can attest to that, having hit a career-high 17 home runs last year, with most of those coming in the time he spent as the club’s regular center fielder.

“That’s a lot of homers,” A’s manager Bob Melvin said. “If you’re looking for a replacement for Khris, that’s the guy.”

Matt Olson provided a three-run blast before Canha, as the two went back-to-back, and Stephen Piscotty also launched a solo home run in the eighth. The three home runs continued the power surge being put together by Oakland's offense, making it 24 home runs over their past 10 games, after hitting just 15 in the 23 games prior to this stretch.

“We’re riding a high right now and when that happens, you have to ride the wave,” Canha said. “We’re doing a good job of that. Just keep that going.”

Mengden the Magician

Daniel Mengden walked a tight rope as he faced bases-loaded jams in the first and third, yet he somehow managed to get through his outing allowing only one run after giving up five hits and five walks. He only lasted four innings, as his pitch count ballooned up to 99 with traffic on the bases every inning, but his ability to limit damage kept the A’s around long enough for the A’s offense and bullpen to pick him up.

“It’s about results,” Melvin said. “We want our starter to go more than four innings, but it just felt like there was a ton of traffic out there and he was behind in the count all the time. You have to give him some credit for making pitches when he really had to.”

Mengden's five walks matched a career high, but one pitch he did have control of was his curveball. He used it as the putaway pitch on three of his four strikeouts, including one he threw that froze up Mallex Smith in the third to strand the bases loaded and keep Seattle off the board.

Getting over the hump

The A’s finally notched a win over the Mariners after dropping their first four meetings of the season.

Key to victory

Home runs always mesmerize, especially when they continue a trend like the A’s find themselves on at the plate, but Oakland's victory on Friday wouldn't have been possible were it not for the ability to strand runners on base by A’s pitchers.

The Mariners left at least one runner on base in seven of nine innings for a total of a season-high 15. A’s closer Blake Treinen also pitched his way out of a jam he created for himself with the bases loaded in the ninth.

“That was the key to the game today. Not giving up the big hit when there were guys on the bases," Melvin said. "It’s difficult to do and we only end up giving up two runs. Wouldn’t have won the game without that.”
