SEATTLE -- Scooter Gennett kept watching and wondering if the pitch he didn't think he hit that well just might carry far enough.
Getting an assist from Seattle right fielder Michael Morse certainly helped.
"Us little guys need all the help we can get," Gennett said.
Gennett capped Milwaukee's six-run seventh inning with a three-run homer off Morse's glove, and the Brewers ruined the Mariners' night honoring former star Ken Griffey Jr. with a 10-0 win on Saturday night.
Griffey was inducted to the team Hall of Fame before the game, then saw his old club give up two big innings to the Brewers. The first three Brewers reached in the seventh without the ball leaving the infield, but Gennett's homer was the big blow. The Brewers added four more in the ninth against Seattle's bullpen.
"I think when the offense is doing that all the way through, hopefully you have a chance to score in more innings," Milwaukee manager Ron Roenicke said. "I know we busted out with the one, but then we added on, which I thought was really good."
Tom Gorzelanny had his best performance of the season for the Brewers. Making his seventh start after beginning the season in the bullpen, Gorzelanny (3-4) gave up just three hits in seven innings.
It was the first time Gorzelanny threw at least seven innings and gave up zero earned runs since July 1, 2011, when he was pitching for the Washington Nationals. He struck out seven and allowed only one batter to reach third base.
"I'm not calling it a renaissance. I'm just trying to do my best out there and have a good effort each time," Gorzelanny said. "I'm not really thinking about what could happen or how things will shake out."
Gorzelanny also pitched through two unique circumstances. The first came right at the start, as the beginning of the game was delayed by 17 minutes because the ceremony honoring Griffey ran long. Gorzelanny ran up into the batting cage underneath the stadium to make a few extra throws, but wasn't bothered by having to wait.
Then he sat through the Brewers' big sixth inning, but was able to make it through the seventh.
"It's great just to get through the sixth inning, which I've had trouble with this year a few times," Gorzelanny said.
Seattle starter Hisashi Iwakuma (10-6) matched Gorzelanny for the first five innings, but quickly fell apart in the sixth.
Carlos Gomez started the inning with a bunt single, diving around the tag attempt of Justin Smoak at first base to reach safely. Iwakuma said he tweaked his back on the play and struggled to get the ball down in the strike zone from then on.
Caleb Gindl then chopped a grounder to the left side as Gomez was running on the pitch. Shortstop Brad Miller fielded the ball, but made the mistake of throwing to first when it was clear he wouldn't get Gindl. That allowed Gomez to reach third and put runners on the corners with no outs.
Khris Davis then hit a shot down to third base that Kyle Seager backhanded. He tried to get Gomez at the plate but his throw was slightly high and Gomez was safe after crashing into catcher Humberto Quintero and knocking the ball free. Quintero stayed down briefly as the inside of his right knee collided with Gomez's right knee, but he remained in the game.
Gomez said Quintero was unhappy being run into and let him know it when he came up for his next at-bat.
"I don't mean to hurt any player, but if he is in front of the plate, what am I going to do?" Gomez said. "You don't have a second to think."
Juan Francisco then doubled to left-center on Iwakuma's next pitch to score Gindl and give the Brewers a 2-0 advantage. Yuniesky Betancourt added an RBI single before Gennett's second homer of the season. Morse had a shot at pulling back the drive, but it deflected off his glove and over the fence.
"I got it a little off the end. I thought it had a chance, but all I was trying to do was get a pitch up and put it in the outfield somewhere," Gennett said.
Said Morse: "I felt like I had a good chance on it till I hit the wall and it kind of jarred my wrist back."
Griffey became the seventh member of the team's Hall of Fame. It was an emotional ceremony that brought the first sellout crowd of the season for the Mariners. The ceremony was supposed to last about 30 minutes, but Griffey's speech was nearly 25 minutes itself and the entire ceremony went for nearly an hour.
