Halsey tries to halt D-Backs' skid

D-Backs look to snap out of slide

The Diamondbacks find themselves in a tough spot after dropping their season-high fourth straight game in a doubleheader sweep by Philadelphia on Saturday night.

Arizona will turn to lefty Brad Halsey to stop the slippage, while the Phillies will counter with southpaw Randy Wolf.

"This is a team made up of veterans and we're able to bounce back and look at [Sunday]," said pitcher Russ Ortiz, who took the loss in Saturday's nightcap despite pitching well. "Hopefully, we'll get two wins over the next two days."

What Arizona needs is more production from the heart of its order. Luis Gonzalez snapped a slump by going 5-for-8 in the doubleheader after going just 1-for-12 on the road trip. But Troy Glaus went 0-for-8 and is 3-for-19 on the trip.
