Golfer Vijay Singh is in the mix of golfers that can win the AT&T National tournament, which ends on Monday.

Singh started the second round from 37th place but in the second round today, he shot 2 under par 68 to lie in 21st place on the leaderboard with a total score of 138.

He is eight shots behind Tiger Woods, who shot a 4-under-par 66 to secure a one-shot lead.

Woods started on the back nine and made five birdies and a bogey in his round to record the lowest-ever 36-hole score at the Congressional Country Club.

The third round will be played tomorrow.
