The Book: A fine player in his own right, Avery fired up Palmer down the stretch of the '60 Masters by asking, " Mr. Palmer, are we choking?" Says Palmer, "Ironman wasn't the greatest caddie, but his understanding of what made me tick was profound."
Jeff (Squeeky) Medlen '91 PGA ( John Daly), '92 PGA, '94 British Open, '94 PGA ( Nick Price).
The Book: On every tee at Crooked Stick in '91, Medlen provided Daly with his winning swing thought, "Kill." Says Price, "When Squeeky and I were clicking in the early '90s, we could read each other's minds."
Dave Musgrove '79 British Open ( Seve Ballesteros), '85 British Open, '88 Masters ( Sandy Lyle), '98 U.S. Open ( Lee Janzen).
