RACE DAY IS HERE — It’s a home game tonight for the NASCAR Sprint Cup Series teams, as they race at Charlotte Motor Speedway in the annual Sprint All-Star Race. The on-track activity begins at 7 p.m. ET with the 40-lap Sprint Showdown last-chance race.

The top two finishers in the Showdown, along with the winner of the Sprint Fan Vote, will advance to the Sprint All-Star Race, which should begin around 9 p.m.

There are 23 drivers entered in the Showdown. A total of 19 drivers are locked into the All-Star Race already, and the final field will be 22 drivers. The race is five segments — four 20-lap preliminaries and one 10-lap finale. The winning driver receives $1 million and if he wins all five segments, that doubles to $2 million.

Weather is an issue. The forecast right now calls for 50-60 percent chance of scattered showers throughout the evening.
