LAST TIME
In September of 2015, Kevin Harvick punched his ticket to advance to the next round of the Chase for the NASCAR Sprint Cup by leading 355 of 400 laps at Dover International Speedway, a career-best at any track. Harvick beat out eventual 2015 Sprint Cup Series champion Kyle Busch by 2.639 seconds for the victory.
YOU SHOULD KNOW
• Chris Buescher (-30 from 12th place), Tony Stewart (-11), Austin Dillon (-5) and Jamie McMurray (-5) are all on the outside looking in as far as the Chase Grid standings are concerned. Of those drivers, Stewart is the only one who has won at the "Monster Mile" -- three times to be exact. Stewart's most recent win came in 2013.
• With 10 wins, six-time Sprint Cup Series champion Jimmie Johnson has been to Dover's Victory Lane more times than any NASCAR driver. Johnson is looking to punch his ticket to the next Chase for the NASCAR Sprint Cup round and a win at his best track could be in the cards.
• Winning the opening XFINITY Series Chase race at Kentucky, Elliott Sadler continues his momentum to Dover where he has earned three top five and 10 top-10 finishes, two of which came in the last two XFINITY Series races at the 1-mile track. Sadler's experience in 17 starts at Dover could shine through on Saturday compared to the young guns he's competing against for the championship.
• Of the Camping World Truck Series Chase drivers, only Johnny Sauter and Timothy Peters have wins at Las Vegas Motor Speedway. Canadian Tire Motorsport Park winner John Hunter Nemechek has the best average finish of 4.0 out of the Truck Series Chase drivers. Behind Nemechek is Ben Kennedy with 5.0. Nemechek has run just one Truck Series race at Dover, while Kennedy has experienced two. In 15 starts, two-time Camping World Truck Series champion Matt Crafton has an average finish of 11.9, but is still seeking a win.
THE FAVORITE
Jimmie Johnson. Who better to pick than the 10-time Dover winner as this weekend's victor? With a championship at stake, Johnson is comfortable under pressure and is looking like a solid pick to win on Sunday.

Others to consider: Kevin Harvick, Martin Truex Jr.
THE SLEEPER
Kyle Larson. In five starts, the No. 42 driver has come as close as second (2016 spring race) to a win at Dover and has earned a total of four top-10 finishes. Larson earned his first Sprint Cup Series win this season and that victory could have given the boost to break the runner-up ceiling at the "Monster Mile."
Others to consider: Tony Stewart, Chase Elliott.
