Rapid Reaction: Cubs 8, Brewers 5

CHICAGO -- Here's a quick look at the Chicago Cubs' 8-5 victory over the Milwaukee Brewers on Friday:

How it happened: This one was over early as the Cubs pounded Milwaukee starter Kyle Lohse with seven runs over the first three innings. Five came in the first when Junior Lake hit his first career grand slam moments after Nate Schierholtz drove in the Cubs' first run. The Brewers scored single runs in the second and third innings on a sacrifice fly by Norichika Aoki and then a solo home run by Aramis Ramirez. But the Cubs got those runs right back on a two-run single by pitcher Chris Rusin. Despite the big lead, Rusin struggled on the mound lasting only 3 2/3 innings pitched. Carlos Villanueva relieved and cruised through the middle innings to get the win but not before Pedro Strop gave up a three-run home run to Scooter Gennett in the eighth. The Cubs got an unearned run back in the bottom of the inning on a throwing error by shortstop Jean Segura. Kevin Gregg pitched the ninth for his 30th save.

What it means: Lake continues to impress with a skillset not many players can claim to possess. After his grand slam, he bunted for a hit with runners on first and second, setting up Rusin's two-run single. According to ESPN Stats and Information, he's just the second player (Michael Bourn) to have a grand slam and bunt hit in the same game this year and fourth in the past five seasons to accomplish that feat. Lake also made a running catch over the bullpen mound in foul territory. ... Rusin might be tiring as he surpassed his career high in innings pitched on Friday. He didn't look sharp and manager Dale Sveum didn't give him a chance at a win -- let alone to get out of the fourth inning -- despite a big lead.

Outside the box: The Cubs tied a franchise record, set last season, using their 53rd player this year. Justin Grimm made his debut in the seventh inning, giving up a walk but no runs. Grimm was acquired in the trade that sent Matt Garza to Texas earlier this year. ... Before the game Sveum said there is a 99 percent chance there will be no more call-ups from the minor leagues after their playoffs are done. The Cubs still have three minor league affiliates playing in the postseason.

What's next: Game 2 of the series is at 3:05 3:05 p.m. Saturday when the Cubs' Jake Arrieta takes on the Brewers' Johnny Hellweg.
