The NASCAR World Cup: Busch vs. Stewart highlights week two

Pocono could go a long way in deciding who's going to be a group winner as seven of our eight groups in The Marbles' NASCAR World Cup feature matchups between the top two cars.

The best of the six should be Kyle Busch and Tony Stewart in Group B. Busch won the pole for the June race and finished second while Stewart finished third in June and has the pole for Sunday's race.

Robby Gordon will not be at the track this week -- as he's testing for Watkins Glen -- so whatever PJ Jones does in Gordon's car will count towards Gordon's statistics.

Group A: Kurt Busch (1-0) v. Brad Keselowski (1-0), Mark Martin (0-1) v. Juan Pablo Montoya (0-1)

Group B: Kyle Busch (1-0) v. Tony Stewart (1-0), Joey Logano (0-1) v. Sam Hornish Jr. (0-1)
