Chez Reavie shot a 7-under-par 63 to burst into the lead of the Travelers Championship in the third round Saturday at TPC River Highlands in Cromwell, Conn.
Reavie birdied the first four holes on the back side and then added three more birdies as part of his 28 on the last nine holes. He's at 16-under 194 for the tournament.
He'll take a six-shot lead on Keegan Bradley and Zack Sucher into Sunday's final round.
Reavie tied for third place in last week's U.S. Open. Now he has come to the other side of the country and he's contending again.
He was 1 over through seven holes before going on the big surge Saturday.
Bradley recovered after hitting his tee shot on No. 15 in the water. He bogeyed that hole, and then posted pars on the final three holes to complete the 69 for the round.
Sucher, who led by two strokes entering the day, shot 71. He was playing with Reavie.
Sucher played the round's first nine holes in 4 under, but a bogey and two double bogeys to begin the back nine not only prevented him from pulling away but sent him suddenly into third place.
Sucher was one of only two golfers in the top 19 to fail to produce a sub-70 third round.
Australia's Jason Day followed his 63 in the second round with a 68 to move into a fourth-place tie with Mexico's Robert Diaz (67). Day overcame bogeys on Nos. 10 and 11 to finish the backside at even par.
"I've got a lot of work," Day said. "Like we say, we're focusing on trying to win this year."
Bryson DeChambeau made a big move with a 64, going to 8-under 202 for the tournament and in a sixth-place tie with Kevin Tway (66), England's Tommy Fleetwood (67) and Scotland's Martin Laird (68).
Defending champion Bubba Watson shot 73, falling to a tie for 51st place at 2 under.
