Mark O'Meara, who won the Masters 20 years ago, said after his round Friday after missing the cut that this would be his last. “I've been very blessed to be a very, very small part of the unbelievable tradition here at the Masters Tournament,'' he said. "To be a guy who made a putt on the 18th green and have Tiger (Woods) put the green jacket on me in 1998. ... I couldn't have asked for any more than that. Now we're 20 years later.'' O'Meara said he had been mulling the decision ."It's just a very, very tough golf course when you're 61.
