Two players that entered the week inside the ending Nationwide Tour Championship.

The top 25 on the money list after this week's event earn their PGA Tour cards for next season.
Though he is projected to remain among those 25 that move on to the PGA next year, first-round leader Mark Anderson did himself no favors on Friday. He struggled to a six-over 78 to tumble into a share of 38th at even-par 144.
Chopra trailed by six at the start of his round, but erased that deficit in his first six holes. He converted birdie chances on the first and second.
The Swede birdied the par-five third and followed with a birdie on No. 4. Chopra got within one as he birdied the fifth to make it five in a row to start the round.
The 37-year-old Chopra two-putted for birdie at the sixth to grab a share of the lead. He parred the seventh, but came right back with a six-foot birdie effort on the eighth.
"The first six holes I just played flawlessly. Pretty much every shot was just about perfect," said Chopra. "When I missed it a little bit, I missed it in the right spot."
Chopra, a who earned his third Nationwide Tour title earlier this year, settled down as he parred six consecutive holes from the ninth.
He caught fire again down the stretch. Chopra sank a seven-footer for birdie on the 15th. After a par on 16, he stuffed his second shot at the par-four 17th within a foot.
Chopra kicked that in for birdie. At the last, Chopra's 210-yard second shot came to rest on the back fringe. He two-putted for birdie from there.
"My caddie said 'That's the longest pitching wedge I've ever seen anyone hit in my life,'" said Chopra of his pitching-wedge second shot to the 18th. "That might have been the greatest shot I hit this year."
Chopra entered the week 24th on the money list.
"I would love to be in the position where I don't have to think about that," stated Chopra, who has two PGA Tour victories to his credit. "Trying to win a golf tournament is going to seem easy in comparison."
Kokrak poured in three consecutive birdie chances from the second to jump into second place at minus-eight. After six pars in a row, he two-putted for birdie from the fringe on the par-five 11th.
The 26-year-old, who won twice this season, had several chances to join Chopra atop the leaderboard, but he didn't do so until the last. Kokrak hit driver, nine-iron at the par-five 18th. He calmly two-putted for birdie and a share of the 36-hole lead.
"I'm in great control of my game. I know where the misses are going to be," Kokrak said in a television interview. "Just controlling my ball-flight in these windy conditions is key. It's nice to a have a bogey-free round today."
