Willie Mosconi - 1 game of 9-ball in exhibition June, 1992
Kim Davenport - local 9-ball tournament, race to 5, 2 game spot and the 7 & 8, ca. 1985 (they might have tied both of his hands behind his back, too)
I know I am not that good and this doesn't mean I beat anybody. But I didn't choke either time when it would have been easy to be thinking about the wrong things. I was playing at my best both times. I was rather impossible at work the next day after playing Willie. I told the golfers to give me a call the next time they played Niclaus.
