Ray Floyd became golf's sixth player to surpass $2 million in PGA Tour career earnings today, shooting a three-under-par 69 to win the $400,000 Danny Thomas-Memphis Classic golf tournament by six strokes.

It was his 17th career victory for Floyd, 39, who has won his last two starts and lost a playoff for the title the week before that. Floyd won $72,000 here, giving him $167,400 in his last three starts. He did not play at the previous tour stop, the Kemper Open, and its champion, Craig Stadler, did not play here.

Floyd has earned $2.022 million in his career. Only Jack Nicklaus, Tom Watson, Lee Trevino, Hale Irwin and Tom Weiskopf have won more.

Floyd's 72-hole total of 271 here was 17 under par for four trips over the Colonial Country Club course, at 7,249 yards the longest on the Tour. He missed Gene Littler's hole record, set in 1975, by one stroke.

"I played very, very well for four rounds and putted tremendously," said Floyd, who was never more than three feet into any rough.

Mike Holland was second at 70--277. His winnings of $43,200 were five times more than his combined total in 19 previous starts this year. Curtis Strange was third at 69--278.
