Rapid Reaction: Phillies 9, Cubs 1

CHICAGO -- A quick look at the Chicago Cubs' 9-1 loss to the Philadelphia Phillies on Wednesday at Wrigley Field.

How it happened: A combination of 97 degree heat and the Phillies' bats made it a short day for Ryan Dempster, who gave up six runs on seven hits in three innings while throwing 86 pitches. It marked his second shortest outing of the season. He threw a 1/3 inning in Arizona on April 28. His ERA shot up to 5.00. The Cubs' offense was shut down by rookie Vance Worley, who gave up just one run through eight innings. Jimmy Rollins hit two home runs.

What it means: The Cubs are 1-8-1 in their last 10 series. The lone win was a one-game makeup win over the Rockies. The Cubs are a season-worst 21 games under .500. The last time the Cubs were 21 games under was Aug. 31, 2010 when they were 56-77.

Outside the box: The Cubs made an error in nine consecutive games for the first time since 1987.

What's next: After a day off on Thursday, Carlos Zambrano (6-5, 4.78) takes on the Houston Astros' Bud Norris (5-6, 3.59).
