What it means: A four-time PGA Tour winner, Campbell has not found his way to the winner’s circle since the 2007 Viking Classic, now known as the Sanderson Farms Championship. In the last six seasons, his best finish is a T-3 at the 2012 FedEx St. Jude Classic. This season, the 41-year-old veteran has made 15 of 25 cuts and turned in two top-10s, a pair of T-8s at the Zurich Classic and FedEx St. Jude. This is the eighth 36-hole lead of Campbell's career, with the last coming at this same event in 2011. Campbell is 1 for 7 lifetime converting 36-hole leads.
Round of the day: Campbell made nine birdies in a bogey-free round, going out in 31 and coming in in 32. He hit 8 of 14 fairways, 12 of 18 greens and needed just 25 putts.
Best of the rest: Hearn, a Brantford, Ontario resident, put together a bogey-free round of his own, a career-low 8-under 64 that has him tied for third and three back of the lead. Hearn is looking to become the first Canadian to win this event since Pat Fletcher in 1954.
Biggest disappointment: Saskatchewan native Graham DeLaet withdrew after just four holes in Round 2. DeLaet injured his left hand hitting a tee shot on the par-3 12th on Thursday. Notables to miss the cut include Graeme McDowell, Ernie Els, Davis Love III, and Patrick Rodgers.
Shots of the day: Bubba Watson’s drives on the 16th and 18th holes went 357 yards and 381 yards, respectively, and led to eagles on both par 5s.
Quote of the day: "That's certainly a nice way to finish." - Watson
Storylines to watch heading into the weekend: The ninth-ranked player in the world, Day is lurking at 10 under, four shots back after rounds of 68-66. The Aussie won earlier this year at Torrey Pines and has five other top-10 finishes. Meanwhile, Watson, No. 3 in the world, played his final four holes 5 under en route to a 67. He sits five back at 9 under. Watson has won twice this season, at the WGC-HSBC Champions in November and at the Travelers last month.
