Leaderboard: Watson (-7), Stenson (-6), Z. Johnson (-6), Finau (-6), Dufner (-6)
What it means: Watson, who co-led after Round 1 with three others, made a late bogey on 17, but an up-and-down birdie from just in front of the 18th green capped off a 2-under 68 and got him into the clubhouse at 7 under. A win this week would give Watson his first FedEx Cup playoffs victory. It would also join him with Jordan Spieth, McIlroy and Jason Day as the only players to win three or more events this season. Those players entered the week Nos. 1-4 in the Official World Golf Rankings, with Watson fourth.
Round of the day: Jason Bohn posted the score of the day and the week with a bogey-free 6-under 64. Bohn made three birdies on each side and sits two shots off the pace after an opening 71.
Best of the rest: Johnson played a bogey-free round of his own, a 5-under 65, to get into a three-way tie for second at 6 under, one back.
Biggest disappointment: Making his first start since ascending to the top of the golf world, Jordan Spieth failed to make the weekend with rounds of 74-73. As a result, he handed back the Official World Golf Ranking’s No. 1 spot to McIlroy, who is inactive this week.
Shot of the day: Day’s approach from the rough at the par-4 10th landed short and right of the green and wound up just 4 feet from the undulated green’s back-left pin position.
Quote of the day: “Bubba needs to hit a lot of drives because he can't really hit it that far. So he needs to get it out there. Obviously a different issue for me.” – Stenson, when asked about strategy off the tee on the treacherous but often-tempting Plainfield layout.
Storylines to watch heading into the weekend: Watson is being chased by two other major winners – Johnson and Dufner – the 2013 FedEx Cup champion – Stenson – and a PGA Tour rookie who hits it almost as far as he does – Finau.
