Hank Kuehne (pictured) and Jeff Sluman combined to fire a 10-under-par 62 and join Steve Flesch and Justin Leonard at the head of the Franklin Templeton Shootout leaderboard.
Flesch and Leonard recorded a second successive 63 to also go into the final round on 18 under par at the Tiburon Golf Course in Naples, Florida.
The top two pairings have a three-shot lead over Greg Norman and Scott McCarron, who carded a 64, and Mark Calcavecchia and Loren Roberts, who enjoyed a 63.
England’s Nick Faldo and American veteran Fred Funk improved on their opening 70 with a 66 but are now 10 shots off the lead.
After an alternate-shot format on day one and a better ball system in the second round, the 12 two-man teams finish with a scramble.
