Paul Casey took a commanding four-shot lead through three rounds of the Travelers Championship by carding a sizzling 8-under 62 Saturday.
Casey put on a remarkable display of golf in Round 3, hitting all 18 greens in regulation for the third time in his career en route to gaining more than seven strokes on the field.
His bogey-free 62, which consisted of six birdies and an eagle, tied his lowest career PGA Tour round.
Russell Henley (-12) is the lone golfer four shots back of Casey after shooting 67 in Round 3. Henley hasn't made a bogey in 41 holes at TPC River Highlands.
Notables Bubba Watson and Jason Day are both at 10-under for the event, putting them in a tie for sixth heading into Sunday.
Watson was within one stroke of the lead before leaking oil down the stretch, bogeying two of his final three holes.
Superstars Rory McIlroy (-8), Justin Thomas (-5), Brooks Koepka (-4), and Jordan Spieth (-3) combined to shoot 1-under for the day. Of the group, only McIlroy sits inside the top 20.
The shot of the day went to James Hahn, who jugged a 158-yard tee shot for a hole-in-one on No. 11.
