LAS VEGAS -- Tony Pedregon won the provisional No. 1 qualifying spot in Funny Car on Friday during the ACDelco Las Vegas NHRA Nationals, moving one step closer to the NHRA POWERade championship.

Tony Schumacher, Greg Anderson and Angelle Savoie also led the way after the second of four qualifying sessions in their respective categories at the $1.6 million race at The Strip at Las Vegas Motor Speedway, the 22nd of 23 events in the $50 million NHRA POWERade Drag Racing Series.

Pedregon leads the category and can clinch the Funny Car championship if he can advance two rounds further than second-place Whit Bazemore. Pedregon used a 4.753-second run at 322.88 mph in a Ford Mustang to lead the first day of qualifying.

"I felt the pressure of being at the top of the standings early in the year and it has been constant,'' Pedregon said. "It's not the most pleasant thing but it is what drives people and it is what tests your character.''

Schumacher led the Top Fuel field with a 4.520 at 331.45 in his U.S. Army dragster. Anderson clinched his first NHRA POWERade Pro Stock championship two weeks ago. He led the category in his Grand Am, going 6.891 at 200.44.

Savoie went to the top of the Pro Stock Bike order with a 7.272 at 188.15 on a Suzuki.

Qualifying continues at 11:30 a.m. and 2:30 p.m. on Saturday before final eliminations begin at 11 a.m. on Sunday.
