Rapid Reaction: Brewers 3, Cubs 2

CHICAGO -- Here’s a quick look at the Chicago Cubs' 3-2 loss to the Milwaukee Brewers in Game 2 of their Tuesday day/night doubleheader at Wrigley Field.

How it happened: Kevin Gregg couldn’t record the save, giving up two runs in the ninth. Starlin Castro's dive and miss of a ball hit by Jeff Bianchi ended up being a two-run single. David DeJesus doubled home both Cubs runs in the seventh inning. Milwaukee got on the board first with a fifth-inning home run by Juan Francisco, the only run given up by newcomer Jake Arrieta. Arrieta pitched well, getting himself into and out of some trouble and only giving up two hits and three walks over six innings.

What it means: Despite the loss, the Cubs are seeing immediate dividends from their trade of Scott Feldman to the Baltimore Orioles as reliever Pedro Strop has been solid and now Arrieta as well in his debut. He hit 95-97 mph consistently while mixing a mid-80’s slider. Every time there was adversity he was able to overcome it, including getting the next three hitters after the home run to Francisco to lead off the fifth. Arrieta is headed back to Triple-A Iowa but not before having a memorable start to his Cubs career.

Outside the box: The Cubs have scored in just two different innings since late in Sunday’s contest in San Francisco. They tallied five runs in the fifth inning of Game 1 on Tuesday and then two in the seventh in Game 2 after being shut out on Monday.

Trade watch: Catcher Dioner Navarro had three hits, raising his batting average to .294 in his last appearance on the field before the trade deadline on Wednesday. … Gregg failed to record his 23rd save in the ninth.

What’s next: The series concludes on Wednesday when the Cubs’ Edwin Jackson faces off against the Brewers’ Wily Peralta.
