Brewers-Mariners Preview

The Associated Press

The Milwaukee Brewers had already dealt with plenty of adversity before finding out their second baseman will miss the remainder of the season due to injury.

That didn't stop them from putting up their best offensive performance in nearly two months in the series opener, and they'll seek their fourth victory in five games against the host Seattle Mariners on Saturday night.

Already dealing with the 65-game suspension of Ryan Braun and a plethora of other injuries to key players, Milwaukee (50-66) learned Friday that Rickie Weeks won't play again in 2013 after tearing his left hamstring in Wednesday's 6-1 win over San Francisco.

''It's too bad,'' manager Ron Roenicke said. ''Because when you have nice ballgames and you're playing OK, you want to enjoy them. But it seems like there's something that always comes up.''

The Brewers didn't let the news immediately bother them, though, as Yuniesky Betancourt hit a grand slam in the fifth inning to help beat his former team 10-5 on Friday.

''I feel a little more excited,'' Betancourt, who spent his first 4 1/2 seasons with the Mariners, said of his return to Seattle. ''I have good memories of here, for the people here.''

Norichika Aoki, who hit .125 in his previous seven games, went 2 for 5 and finished with three RBIs for Milwaukee, which hadn't scored that many runs since a 10-1 win over Miami on June 12.

The Brewers' offense may have more difficulty Saturday as Hisashi Iwakuma takes the mound for Seattle.

Iwakuma (10-5, 2.75 ERA) has been solid over his last five starts, going 3-1 with a 1.91 ERA. He allowed two runs in 7 1-3 innings Monday versus Toronto but was saddled with a 3-1 defeat.

It marked his first loss in 10 starts in which he pitched at least seven innings and allowed two runs or fewer after allowing both runs in the eighth.

''He pitched a really good game,'' acting manager Robby Thompson said. ''We felt he was our best guy to send back out there for that eighth inning.''

The right-hander ranks fifth in the AL in ERA despite going 0-3 with a 6.83 mark in the five starts before his current stretch.

Seattle (53-62) has dropped seven of 10, with the pitching staff posting a 5.13 ERA after allowing at least 10 runs for the 16th time.

Justin Smoak hit a two-run homer in the eighth and Kyle Seager also drove in two runs for the Mariners, who look to bounce back against Brewers starter Tom Gorzelanny, who makes his first start in eight days.

Gorzelanny (2-4, 2.78) was 1-3 with a 3.33 ERA in five starts before leaving his most recent outing after being struck on the left elbow with a line drive in the second inning Aug. 2. Milwaukee went on to lose that game 4-1 to Washington.

He missed his next scheduled start Wednesday and threw a bullpen session instead.

"I felt like I was good to go (Wednesday), but we were just being cautious with it," said Gorzelanny, who officially was diagnosed with a contusion. "There was still a little swelling in there and we didn't want to risk it. A couple extra days (rest won't hurt)."

The left-hander last faced Seattle in 2010 when he picked up a save for the Chicago Cubs.
