Naples, Florida - Jason Day and Cameron Tringale shot a 17-under 55 on Thursday in the first-round scramble to take a two-stroke lead in the Franklin Templeton Shootout.
"The abridged version is, I hit first and then let Jason loose," Tringale said.
Day and Tringale tied the tournament scramble record set by tournament host Greg Norman and Nick Price in 1993 and matched by Peter Jacobsen and John Cook in 1998 and Norman and Steve Elkington in 2005.
"Scramble is one of those formats where you have to go at it and shoot lights out," Day said. "It definitely helps when you have a partner who hits it down the middle all the time and putts great."
They were 12 under on the last 12 holes at The Ritz-Carlton Golf Resort, making eagles on Nos. 13 and 14 and birdies on Nos. 9-12 and 15-18.
"It's great to be able to read the putt together, really put our minds together, because he's a great putter," Day said. "He always has been."
Defending champions Matt Kuchar and Harris English opened with a 57. They birdied 14 of their last 15 holes.
"To go 15 is great," Kuchar said. "To go 17 is quite amazing.
All 12 teams were 11 under or better. The teams will play a modified alternate shot on Friday and close with a better-ball round on Saturday.
English thinks they separated themselves last year in the modified alternate shot.
"I feel like we can do the same thing as we did last year," English said. "Kooch is driving it great right now, so we're going to kind of lean on that."
Keegan Bradley-Camilo Villegas, Graeme McDowell-Gary Woodland and Ryan Palmer-Jimmy Walker shot 59.
Patrick Reed played two days after wife Justine suffered a grand mal seizure.
"We are really fortunate that she is OK," Reed said.
Reed, a late replacement for Chris Kirk, teamed with Brandt Snedeker to shoot 61. They were tied for 10th.
