The wild, two-putter strategy proved a two-edged sword. Mark Calcavecchia carried two flat clubs - one short, one long - in his bag during The Barclays, and while they combined to help him tie for fourth, the strategy hurt him at the very end. I carried two putters all week - using my short putter on longer ones, my belly putter on shorter ones. It was a pretty good idea as it turned out," Calcavecchia said after yesterday's 6-under 65 gave him a 12-under finish at Westchester Country Club. But he came to the 72nd hole and faced a two-putter dilemma. "I actually overthought myself. With two putters in my bag, I have a gap between my 3-wood and 3-iron, about a 50-yard gap," Calcavecchia said. "I was afraid if I hit a good drive I'd be right in the middle, where I couldn't get it there with a 3-iron, and a 3-wood would be way too much."
