The screws begin to tighten Saturday at Charlotte Motor Speedway.
That's when NASCAR's Chase will move into its second round, in the Bank of America 500 at the 1.5-mile track in Concord. It's down to 12 drivers now, after four were eliminated Sunday at Dover (Del.) International Speedway.
Martin Truex Jr. won two races in the first round of the Chase, with Kevin Harvick claiming the other victory.
They go back to even with the other 10 remaining Chase drivers now, though.
Here's a look at how the second round might play out over the next three races at Charlotte, Kansas and Talladega. The top eight will advance to the third round.
