After turning professional in 1980 and earning the PGA TOUR's 1981 Rookie of the Year status, Mark O'Meara saw his first victory at the 1984 Greater Milwaukee Open. He posted four consecutive rounds in the 60s, ending up with a five-stroke margin over Tom Watson.

Since then, Mark has proved to be one of the PGA TOUR's most successful members, sitting in 50th place on the all-time wins list with a total of 16 victories. Six of those victories came at pro-am events, and he was the first player to ever earn five wins at the legendary AT&T Pebble Beach National Pro-Am.

He joined the ranks of golf's elite in 1998 when he captured his first major championship at the 1998 Masters Tournament, his 14th start at the event. His second major championship came just a few months later at July's British Open Championship, where he defeated Brian Watts in a four-hole playoff. At 41, Mark became the oldest player on the PGA TOUR to capture two major championships in the same season and was awarded the PGA TOUR Player of the Year Award. He was also named Player of the Year by PGA of America and the Golf Writers Association of America.

In 2007, Mark joined the Champions Tour. He broke through for his first Champions Tour win when he teamed with Nick Price to win the Legends Division at the Liberty Mutual Legends of Golf in a two-hole playoff with John Cook and Joey Sindelar. His first individual title came several months later when he prevailed in a one-hole playoff over Michael Allen at the Constellation Energy Senior Players Championship.

An avid fly-fisherman, Mark is also involved in golf course design. On TOUR he represents several companies, including Lexus, and currently drives a Lexus LS 460.
