Tom Watson-Gap Rating 5/10

In the period of time between Jack Nicklaus' peak and Tiger Woods' peak, Watson was head-and-shoulders above any other golfer in the world.

Watson stood up to Nicklaus on numerous occasions, one of the few golfers who consistently went toe-to-toe with Nicklaus and came out on top.

Their duel at the 1977 British Open - where Nicklaus shot 66-66 over the final two rounds, while Watson shot 66-65 to win by one - is one of the greatest head-to-head battles the sport has ever seen. Watson robbed Nicklaus of another major at the 1982 U.S. Open with his famous chip-in on the 17th hole at Pebble Beach.

Watson played golf at Stanford University and graduated with a degree in psychology. He turned pro in 1971, but in his early years got the reputation of a player who wilted under pressure.

Watson began working with Byron Nelson, who would become a great friend and mentor, and in 1974 broke through with his first PGA Tour victory. In 1975, he won the Byron Nelson Classic, then his first British Open title. Watson was off and running.

He would go on to win the British Open a total of five times; the Masters twice, and the U.S. Open once. He led the PGA Tour in wins six years, in money five years, in scoring three years. He was PGA Tour Player of the Year six times.

During those years, Watson was an aggressive putter, fabulous chipper and unsurpassed from tee to green.

His final PGA Tour victory came in 1998. In 1999, he began playing on the Senior PGA Tour. Watson was Player of the Year in 2003, but the year also was marked by sadness: his longtime caddie, Bruce Edwards, was diagnosed with Lou Gehrig's Disease. Watson co-founded an organization, Driving 4 Life, to fight ALS. He donated $1 million to the foundation, and during 2003 alone Watson helped raise nearly $3 million for ALS-related causes and other charities.

Tom Watson was inducted into the World Golf Hall of Fame in 1988.
