PARAMUS, N.J. - Jason Day had three late birdies in a 4-under 67 on Friday and he held a one-stroke lead after two rounds in The Barclays.
Nine players had at least a share of the lead at some point during the second round until Day's late surge. He was at 8-under 134, one shot clear of Kevin Streelman (63) and Vaughn Taylor (70) going into the weekend of the FedEx Cup's first playoff event.
Tiger Woods missed a 20-inch par putt on the fifth hole and wound up with a 73, eight shots worse than his opening round.
The good news for the world's No. 1 player - he will stay atop the world ranking for at least another week after Phil Mickelson missed the cut.
Streelman ran off six birdies in a seven-hole stretch at the Ridgeway Country Club course.
Stewart Cink raised his Ryder Cup hopes with a 69 that put him in a group at 6-under 136 with Martin Laird (67) and John Senden (69).

Shin is ranked No. 4 on the World Rolex Rankings and has nine top-10 finishes this season.

U.S. Amateur
UNIVERSITY PLACE - Peter Uihlein put his hands out with an almost apologetic look on his face after dropping a 5-foot putt to win his quarterfinal match at the U.S. Amateur on Friday.
Beating his college teammate, and one-time roommate, wasn't very enjoyable for the top-ranked American amateur.
"It's bittersweet. I just took out one of my best friends. It's hard because seeing him after, he wasn't happy," Uihlein said of his 1-up win over Oklahoma State teammate Morgan Hoffmann. "It's hard for me to be excited when I just played him."
A day after only a few of the 24 matches even reached the 17th or 18th holes, all the quarterfinals made it to at least No. 18, with Patrick Cantlay needing 20 holes to win his match.
Uihlein and Cantlay will meet in one semifinal on today morning. The other will be a Cal-Stanford matchup, with defending champion Byeong-Hun An facing Stanford's David Chung.
