Sport: 2021 Xfinity 500 odds, predictions: Model reveals surprising picks for Martinsville, NASCAR Playoffs

Analysis: Kansas performance a must for three playoff drivers

  Analysis: Kansas performance a must for three playoff drivers Today's race in Kansas offers opportunity that may not exist at Martinsville for Brad Keselowski, Kyle Busch and Joey Logano.A potentially unexpected byproduct of NASCAR becoming a split-horsepower series is the ability of teams to choose their paths of focus. Among the remaining seven playoff drivers not already locked into the Championship 4, just three — Denny Hamlin, Chase Elliott and Ryan Blaney — have elite metrics across both 550 and 750-horsepower tracks.

Martinsville Speedway began hosting the NASCAR Cup Series in 1949, and the 0.526-mile paperclip-shaped oval will host the 2021 Xfinity 500 on Sunday. It's the penultimate race of the 2021 NASCAR Playoffs and Kyle Larson is the only driver who has secured a spot in the championship. Denny Hamlin, Chase Elliott, Kyle Busch, Brad Keselowski, Ryan Blaney, Martin Truex Jr. and Joey Logano will fight it out for the other three spots when the green flag drops at 2 p.m. ET.

Martinsville storylines: Keep it together

  Martinsville storylines: Keep it together In his last three Martinsville races, Ryan Blaney has been hurt by pit road miscues. In Sunday's Round of 8 eliminator, he can't afford more mistakes.The Team Penske driver has been a contender to win in his last three visits to the Virginia half-mile track. But he came away empty-handed each time.

Top 2021 Xfinity 500 predictions

One surprise: the model is high on Kurt Busch, even though he's a 50-1 long shot in the latest NASCAR at Martinsville odds 2021. He's a target for anyone looking for a huge payday. The 43-year-old proved that he can still compete at the highest level with a late-season win in Atlanta to cement his place in the 2021 NASCAR Playoffs, but was eliminated after the Round of 12.

Still, the victory was his 33rd in the NASCAR Cup Series and now he returns to a track where he's had plenty of success. Busch is a two-time winner in Martinsville, and after recording only three other top-10s besides his victories in his first 36 starts at "The Paperclip," he's finished 10th or better in four of his last six starts there.

And a massive shocker: Chase Elliott, one of the Vegas favorites at 6-1, stumbles big-time and barely cracks the top 10. There are far better values in this loaded 2021 Xfinity 500 starting lineup. The defending NASCAR Cup Series champion is back up to second in the 2021 NASCAR standings after a second-place finish last week in Kansas.

Friday 5: Dale Jr. breaks down playoff field heading into Martinsville

  Friday 5: Dale Jr. breaks down playoff field heading into Martinsville NBC Sports analyst Dale Earnhardt Jr. shares his thoughts on the seven Cup playoff drivers fighting for the three spots to the championship race.Seven drivers remain in contention for the final three spots in the Cup championship race entering Sunday’s elimination race (2 p.m. ET, NBC and Peacock Premium). Only Kyle Larson has secured a spot in the Nov. 7 title race at Phoenix Raceway.

However, his only two wins this season have come on road courses and he's finished outside the top 10 in four of the eight races so far in the NASCAR postseason. Elliott is also in position with a 33-point cushion over the fourth-place bubble and he's likely to race more conservatively on Sunday to lock up his spot in the Championship 4.
