SEATTLE -- The smile on Robinson Cano's face said it all Tuesday night.

After finally delivering in the clutch -- a rarity for the Seattle Mariners' $240 million man this season -- Cano flashed a grin that showed both excitement and relief.

"It's good to be able to come through in that situation," he said after walking off with an RBI single in the bottom of the 11thinning for a 7-6 win over the Detroit Tigers. "I've been in it a lot this season and haven't been able to come through."

Cano ended a night of home runs late Tuesday, when his single into the right-field corner drove in the winning run in the bottom of the 11th inning. The second baseman's sixth career walk-off hit, and his first since 2009, brought home center fielder Austin Jackson from second base to end a game that lasted 3 hours, 44 minutes and included seven home runs.

All of the game's runs except for the last one scored on a homer. And yet Cano's line drive into the corner was one of the most clear-cut hits of the evening.

"When he hit it," Jackson said, "you knew that was it right there."

Left fielder Yoenis Cespedes, catcher Alex Avila, third baseman Nick Castellanos and first baseman Marc Krauss, who was making his Tigers debut, all homered for Detroit. Seattle got home runs from Jackson, left fielder Franklin Gutierrez and Cano.

The Tigers have hit eight home runs over the first two games of the series.

"You don't see this many home runs hit in a couple of games," Detroit manager Brad Ausmus said, "and with a day game (Wednesday), there's a chance for even more. ... It's been a big oddity."

Neither starting pitcher factored into the decision after allowing a combined five home runs.

Seattle's Taijuan Walker won each of his previous five starts, but that streak ended when he gave up six hits, three home runs and five runs in six innings -- his worst performance since mid-May.

Detroit starter Kyle Ryan was pulled after just 2 2/3 innings. The left-hander allowed six hits and five runs and was optioned to Triple-A Toledo after the game.

Tigers reliever Ian Krol (1-2) served up the game-winning hit, while Mariners reliever Charlie Furbush (1-1) earned the win after pitching his way out of a jam in the top of the 11th.

Detroit (42-41) opened off the 11th with a double from designated hitter Victor Martinez and an intentional walk but ended up stranding both runners when Furbush struck out the next three batters.

"We've had trouble scoring runs in extra innings all year," said Ausmus, whose team is now 3-6 in games decided after the ninth. "... We had some opportunities (Tuesday); we just couldn't do it."

The Mariners (39-45) got their own threat going in the 11th with a leadoff single from shortstop Brad Miller and a one-out single from Gutierrez after Austin had reached on fielder's choice. That put runners at first and second, setting the stage for Cano's game-winner.

Cano went 2-for-4 in the game and is hitting .253 this season, and his streak of five consecutive All-Star Game appearances will come to an end. Cano's well-documented struggles have been a big reason why the Mariners have underachieved thus far, but his teammates believe he's on the cusp of breaking out in a big way.

"You look at the average and it looks like he's struggling," Jackson said "but we know in (the Mariners' clubhouse) that you want him in those situations."

NOTES: The Tigers officially added 1B Marc Krauss to the roster, and he went 1-for-4 with a homer and three strikeouts. Krauss was claimed off waivers Monday, and Detroit designated INF Josh Wilson for assignment to clear a roster spot for him Tuesday. ... Mariners manager Lloyd McClendon was away for the second day in a row Tuesday, leaving bench coach Trent Jewett to run the team. McClendon was in Indiana to attend the funeral of his younger sister, Angela Price, who died last week at the age of 44. ... .. Mariners RHP Taijuan Walker issued a base on balls to Detroit C Alex Avila with one out in the second inning Tuesday. That snapped a streak of 111 consecutive batters faced by Walker without a walk. ... The Tigers finished with nine hits, ending their streak of double-digit hits at seven games. ... The Tigers optioned Ryan to Triple-A after the game and re-called RHP Buck Farmer.
