Rapid Reaction: Cubs 4, Tigers 3

CHICAGO -- Here's a quick look at the Cubs' win against the Detroit Tigers on Tuesday night.

How it happened: A pair of throwing errors byJhonny Peralta gave the North Sider’s the lead in the 9th inning, and they held on. The Cubs took their first lead on Detroit starter Max Scherzer in the second inning when Bryan LaHair’s walk turned into an eventual run as he scored on Darwin Barney’s ground out. Barney drove in two more in the 6th with a double. The Tigers knocked out Paul Maholm in the 7th, scoring twice off the lefty and once on reliever Casey Coleman. Maholm was saved by a nasty east wind that turned surefire home runs in the 6th inning by Miguel Cabrera and Prince Fielder into easy fly outs in left center.

What it means: The Cubs started the post Rudy Jaramillo era with two innings that produced leadoff walks, the precursor to better at-bats and on-base percentage. (Jaramillo, the team’s former hitting coach, was fired Tuesday.) Three of the Cubs’ first four walks scored to hammer home the front office’s emphasis on plate patience. The Cubs average 2.5 walks per game (second worst in baseball). They seven walks in Tuesday’s win.

Outside the box: The outfield at Wrigley looked like a tractor pull took place as the entire field was wiped out by back-to-back concerts over the weekend . The entire outfield turf will be replaced after the home stand, according to a source.

Up next: Right-hander Matt Garza (2-4, 3.99 ERA) faces Rick Porcello (3-4, 5.03 ) in Game 2 of the three-game set.
