It had been a while since the Milwaukee Brewers came out on the right side of a laugher.

Led by Kyle Lohse’s team-leading 15th quality start and Yuniesky Betancourt’s second grand slam of the season the Brewers pummeled the Seattle Mariners 10-5 in an interleague matchup on Friday night at Safeco Field.

It was the Brewers’ first trip to Seattle since Aug. 11-12 1997 and they celebrated their return by reaching double digits in runs for the first time since beating the Miami Marlins 10-1 on June 12.

"Real good win" manager Ron Roenicke said. "Anytime we score 10 runs it's a great offensive day. There was really a lot of good things offensively."

Shoddy defense by the Mariners helped the Brewers get onto the scoreboard first as consecutive one-out errors in the third inning set the stage for a two-RBI ground-rule double by Norichika Aoki.

Seattle battled back to tie it in the bottom of the frame on a two-RBI single by Kyle Seager.

Milwaukee added three more runs in a third inning that saw Roenicke ejected for the second time this season. Roenicke argued vehemently with home-plate umpire Dan Bellino when a run scored by Carlos Gomez was disallowed because of fan interference.

"I didn't argue the point that it hit a fan because I don't know" he said. "I'm closer than the home-plate umpire is to it and I didn't know if it hit him or not. The home-plate umpire was the only one who didn't see it hit the guy's arm so the other three got together and all three of them said it hit the fan.

"I didn't argue that. What I argued was it didn't affect the ball coming off the wall. They didn't even make an attempt to get 'Gomey' at home so he should have scored. So the one guy who didn't see the play he's the one who rules whether the run scores or not.

"How can they ask him? He didn't see it hit the spectator so how does he know how the ball comes off? All of them should have gotten together and decided 'OK how does that affect it and does he score anyway?' You don't leave it to the guy at home plate who doesn't see the play."

It was Roenicke’s second ejection of the season. The first one came on April 23 in San Diego when he was booted for arguing balls and strikes with Gary Darling.

"I stayed out too long" he said. "I should have been kicked out. I just told him that he took the easy route out which he did. He took the easy call which is spectator interferes and you just give the guy a double.
