After three days of calm weather, the wind kicked up during the final round on Saturday and scores went up.
Bobby Cole, the leader at 54 holes after back-to-back rounds of 66, shot a four-over 76 and missed the playoff by a stroke.
Watson managed an even-par 72, capped with a 20-foot (6 m) birdie putt on the 72nd hole to tie Newton, who shot 74 (+2).
The Sunday playoff was back-and-forth in the rain,[3] and included a chip-in eagle by Watson at the 14th hole, the short par-5 named "Spectacles."
[4] Watson was on the 90th green in two with about 25 feet (8 m) for birdie, but Newton's approach ended in the front left bunker.
