PALMDALE, Calif. - Firefighters plan an aggressive air attack at first light Friday against a fast-moving wildfire that exploded in northern Los Angeles County, chewing through more than 7 square miles of dry brush, forcing hundreds of evacuations and burning at least three structures.

There is zero containment, authorities said.

Three water-dropping helicopters and hundreds of firefighters worked through the night to get ahead of the blaze which broke out around 3 p.m. Thursday on the northern side of State Route 14.

PHILADELPHIA - There's a new Roy in town - and he's an ace, too.

Three-time All-Star Roy Oswalt gave his OK to a trade from Houston to Philadelphia on Thursday, becoming the latest star pitcher to join the hard-charging Phillies.

After getting Roy Halladay in the offseason, the two-time defending NL champions got Oswalt and a sizable amount of cash from the Astros for pitcher J.A. Happ and two speedy prospects, outfielder Anthony Gose and shortstop Jonathan Villar.
