They were rivals in a United States/South Africa junior match play competition back in 1977 and playing partners at the PGA Championship at Winged Foot 20 years after that. Now both in their early 50s, Mark Calcavecchia and David Frost are at it again.
Paired together for a second consecutive day after each shot 8 under Friday in the 3M Championship, the two matched scores once more Saturday at TPC Twin Cities in Blaine. Each carded a 6-under-par 66 to get to 14 under for the tournament.
They have a two-shot lead heading into Sunday's final round over John Cook, David Peoples and former club pro Kirk Hanefeld.
Saturday was another banner scoring day, with 47 players in the 78-man field finishing with subpar rounds.
"I fully expect Frostie to shoot [another] good score and whoever we're playing with to shoot a good score," Calcavecchia said, noting the likelihood of a third day in a row of squishy soft greens. "So that means if I have any designs on winning, I have to shoot one better."
Calcavecchia, making only his fifth Champions Tour start this week since turning 50 in June, got to as low as 16 under Saturday after a birdie at the par-4 16th. But bogeys on the final two holes left him without the solo lead.
"I'm glad there's no more holes left; I probably would have bogeyed the next one, too," Calcavecchia grumbled. "Some days you leave the course happy, some days you don't. I'll regroup for [Sunday]. I'm playing well."
Add Frost to that mix.
