Nicklaus says he might not return

AUGUSTA, Ga. -- Jack Nicklaus, who has won the Masters a record six times and shot himself into contention with a 2-under-par 70 in the second round, raised the possibility Sunday that this might be the last time he plays in the tournament.

Nicklaus, 60, closed his tournament 81-78 to finish at 15-over-par 303, his worst four-round total in 41 Masters. He had never shot a round in the 80s in the tournament.

''It's possible that was my last walk at 18,'' he said.

Nicklaus' experience at this year's tournament soured on the back nine Saturday, when he shot an 8-over 44 in windy, cold conditions.

''I didn't have any enthusiasm,'' Nicklaus said of the third and fourth rounds. ''I didn't make anything happen, had a nice six-bogey round.''

Nicklaus said his fitness and health are not factors.
