Mattiace is the reigning FedEx St. Jude Classic champion. He shot 64 in the final round a year ago to overcome a seven-stroke final-round deficit and edge out Tim Petrovic.
Now, he returns to the par-71 Tournament Players Club at Southwind a far more famous man than when he left with the trophy.
Mattiace, of course, lost to Mike Weir in a playoff in this years Masters Tournament. He gained acclaim, however, for his Sunday 65, and for the emotion he showed in defeat.
Since then, he has failed to finish inside the top 30 in six tournaments, and pulled out of last weeks Buick Classic. He tied for 57th in the U.S. Open.
This is the 46th playing of the event; it's the 15th time Southwind has been host.
Three players have won the tournament on multiple occasions, two of who successfully defended their title. Dave Hill won in 1967, 69 and 70. Lee Trevino prevailed in 1971, 72 and 80. Nick Price was tops in 1993 and again in 98.
Past champions also include Jack Nicklaus (1965), Gary Player (1974), Raymond Floyd (1982), Hal Sutton (1985), Curtis Strange (1987), Tom Kite (1990), Fred Couples (1991) and Greg Norman (1997).
John Cook owns the 72-hole tournament scoring record, with a 258 total (26-under par) in 1996. Al Geiberger shot the magical No. 59 in the second round of this event in 1977.
