CROMWELL, Conn. (AP) -- Paul Casey has come close each of the three previous times he has played in Connecticut. He has a great chance to break through Sunday in the Travelers Championship.
Casey shot an 8-under 62 on Saturday to take a four-stroke lead into the final round.
Casey, whose win at Valspar in Florida in March was his first PGA Tour title in nine years, called the bogey-free round at TPC River Highlands his best of the year.
The Englishman had six birdies and an eagle - at the signature par-4 15th hole - where he hit his tee shot onto the green and then sank a 23-foot putt. He broke out of the pack hitting all 18 greens and has a streak of 23 straight heading into Sunday. He was at 16-under 194.
''It was clinical,'' he said. ''I did everything I wanted to do. I can't do any more than that.''
Casey was second here during his first visit in 2015, came in 17th a year later and had a fifth-place finish in Cromwell a year ago.
''I love this golf course,'' he said.
''I think I can shoot a low number on this course,'' Henley said. ''You've got to make the putts. I'm definitely hitting it well enough, and if I can get a couple putts to fall, that would be good. But I can't control what (Casey) is doing. I can just try to keep playing solid.''
Jason Day shot 66, and Bubba Watson 67, leaving them 10 under. Watson came from six back to the 2010 event and beat Casey in a playoff in 2015.
Watson would join Billy Casper as the only players to win this tournament more than twice. Casper won his fourth Connecticut title in 1973.
''I'm hoping the weather is real sunny when I'm teeing off and as soon as I putt out it gets windy and a little be of rain and gives me a better shot at it,'' he said.
Morning rain and drizzle throughout the day kept the greens soft, but nobody was able to stay with Casey.
The shot of the day came from James Hahn, who aced the 154-yard 11th hole. Hahn's tee shot went over the greenside bunker on the right front of the hole, struck the bottom of the flag pole and went into the hole, which required some repair work to the front lip after taking the hit.
''Sorry, not sorry,'' joked Hahn, who said this was the sixth or seventh ace of his lifetime, but the first on Tour.
U.S. Open champion Brooks Koepka shot a 69 to get to 4 under. Koepka said he plans to go right at every pin Sunday, then take time off from golf before the British Open.
''I'm going to try to shoot 60,'' he said. ''You're so far back, you've got to kind of make a move and if you shoot 10 (under), you never know what can happen.
It was a bit of a squirrely round, quite literally for Rory McIlroy.
His opening tee shot was delayed when a squirrel camped right in front of him in the tee box. McIlroy finally got the shot off, hitting it wide right and into the rough en route to a bogey.
McIlroy had an eagle at 15, but three-putted 18 for a bogey and a 69. He was tied for 15th place at 8 under.
Defending champion Jordan Spieth was 3 under after a 71. He opened 63-73.
