Who was the only player to win the U.S. Open on three different surfaces, grass and clay at Forest Hills and hard court at Flushing Meadows?

Jimmy Connors won the US Open on grass at Forest Hills in 1974, on clay at Forest Hills in 1976, and then on hard courts at Flushing Meadows in 1982 and 1983. This makes him unique as the only player to have won the US Open on three different surfaces before the tournament permanently moved to hard courts. McEnroe won only on hard courts, Borg never won the US Open, and Sampras won only on hard courts.
