With Jordan Spieth showing surprising signs of weakness, Bubba Watson has an opening to make a move at the FedEx Cup over the next month.
Watson broke a four-man tie with a 2-under 68 to drop to 7-under, opening up a one-stroke lead over four competitors, including world No. 9 Henrik Stenson and The Open Championship winner Zach Johnson.
For a second consecutive day, Watson had two bogeys, but overcame them with a flurry of birdies.
Johnson fired a 5-under 65 to jump from 32nd to second. Even he wasn’t as hot as Jason Bohn, who shot a 6-under 64 to reach 5-under, tied for sixth after starting the day in 58th.
Bohn was a non-factor for the first 16 holes on Thursday, 3 over at that point before birdying 17 and 18. He stayed hot on Friday, with six birdies and no bogeys.
US Open champion Jason Day, who had planned to pull out of the tournament, instead fired his second consecutive 68 and is 4-under, tied for eighth.
