AUGUSTA, Ga. -- Tom Watson wouldn't be surprised to see Fred Couples slip on another Green Jacket on Sunday ... even at the age of 51.
"It's not out of the realm of possibilities," the two-time Masters champ said. "It can work. ... Freddie knows the golf course very well."
Couples shot a 4-under 68 on Friday to leave him at 5 under through 36 holes, firmly in striking distance heading into the weekend.
Should Couples win, he would be the oldest Masters champ in history. Jack Nicklaus holds the record for oldest champ with his memorable win 25 years ago at the age of 46.
Couples finished sixth last year at the age of 50. Watson said Couples has a big advantage with length but that it will be on the greens that likely decides his fate this weekend.
"Jack (Nicklaus) said it right -- he said this is a young man's golf course as far as nerves on putting," Watson said.
