Rapid Reaction: Brewers 12, Cubs 4

MILWAUKEE -- The Chicago Cubs lost to the Milwaukee Brewers on Saturday night 12-4. Here's a quick look at the game.

How it happened: Milwaukee broke open a 6-4 contest with a five-run fifth inning as pinch hitter Jason Rogers hit his first career home run -- a 3-run shot -- off of reliever Phil Coke. Earlier, Kris Bryant homered for the first time in his career, also a 3-run home run but the Cubs couldn't hold a 3-2 lead for very long as Milwaukee scored runs in innings 2 through 6. Travis Wood lasted four innings while Edwin Jackson failed to get an out before being pulled in favor of Coke. Jackson gave up three runs while Jason Motte gave up one in the sixth. The Cubs bats went silent after the fourth inning as they got blown out.

What it means: A slow meltdown of the pitching staff came to a head on Saturday as not one Cubs pitcher -- while the game's outcome was still in doubt -- had it easy or made it easy on himself . For the second consecutive outing Wood was handed a lead and he immediately gave it back. Jackson had nothing going, walking two and giving up a hit while Coke and Motte also struggled. The staff has been infected by something contagious and either the Cubs can hope it cures itself -- sometimes it does -- or they can make changes. Coke and Jackson have to be on thin ice, though Jackson's contract continues to present problems. Maybe it's just a bad stretch but the Cubs need to prepare for the worst -- right now it seems to be happening.

Bryant's first: Bryant's home run came off a slider from Kyle Lohse ending an amateur and professional career long 20 games without hitting one out. It was also the Cubs first 3-run home run this season.

Ross pitches: Catcher David Ross pitched the eighth inning, getting Hector Gomez on a fly ball to center, Scooter Gennett on a ground ball to third and Adam Lind on a ground ball to second. It was the Cubs first 1-2-3 inning since the first inning of the game.

Russell at short/Coghlan at first: Regular outfielder Chris Coghlan subbed in at first base for Anthony Rizzo to start the seventh as Joe Maddon gave some regulars a rest. Addison Russell saw his first career action at shortstop as Starlin Castro took a break. Though mostly an outfielder with the Cubs, Coghlan has played third, second and now first base this season.

What's next: The rubber game of the series takes place on Sunday afternoon when Kyle Hendricks (0-1, 5.61) takes on Matt Garza (2-4, 4.58).
