Only three unclaimed spots remain for Saturday night’s NASCAR Sprint All-Star Race. And 23 drivers will race hard to nab one of them in the Sprint Showdown (7:30 p.m. ET on SPEED), the precursor to the main event scheduled to start at about 9 p.m. ET.

Among that list of 23 are rookies, veterans, winners and former Chase for the NASCAR Sprint Cup contenders. Three rookies pepper the fields: Danica Patrick, Ricky Stenhouse Jr. and Timmy Hill. Martin Truex Jr. had a career year last year, making the Chase and vying for a championship. He’ll join Jeff Burton and Juan Pablo Montoya as former Chasers who have yet to lock up a spot.

David Reutimann is a two-time NASCAR Sprint Cup Series winner. Jamie McMurray has won on NASCAR’s biggest stage – the Daytona 500. Paul Menard has “Kissed the Bricks” at Indianapolis Motor Speedway. Bobby Labonte has won a championship. None of them have locked up a spot yet.

Though Aric Almirola has yet win a NASCAR Sprint Cup race, his 2013 story hints at a sooner-than-later victory. His string of four consecutive top-10 finishes snapped at Darlington, but he remains ninth in points. He has yet to claim an all-star nod.

The top-two finishers in the Sprint Showdown will earn a bid into the NASCAR Sprint All-Star Race. In addition, the top vote-getter in the Sprint Fan Vote will earn a spot in the ‘big show.’ Fans may vote for their favorite driver by using the NASCAR Mobile ’13 application or online at NASCAR.com/SprintFanVote. Votes cast from the NASCAR Mobile ’13 application count double.
