Career

After winning the NCAA Singles championships in 1976 as a sophomore for Trinity University (upsetting UCLA's Peter Fleming), Scanlon turned pro and, in his first Grand Prix event, defeated world #7 Harold Solomon to reach the quarter-finals. His first ever ATP singles ranking was #154. Later that summer, Scanlon defeated world #4 Adriano Panatta at the US Open and, with two wins over former world #1 Ilie Năstase in early 1977, climbed the rankings to #23 by March of 1977.

After a frustrating season in 1978, Scanlon rebounded in his final tournament of the year to take the title in Maui with wins over John McEnroe, Harold Solomon and Peter Fleming. In 1979 he reached the quarter-finals of Wimbledon (losing to Jimmy Connors) before successfully defending his title in Maui, again beating Fleming in the final.

Scanlon peaked in 1983 when he reached the semi-finals of the US Open . He defeated Pat Cash, Chris Lewis, Henrik Sundström and John McEnroe before losing to Jimmy Connors.

In 1985 Scanlon underwent two knee surgeries, missing most of the season. He continued to compete through 1989, winning one more singles title, the Hall of Fame Championships in Newport, Rhode Island in 1986.

During his career, Scanlon would log wins over eight players who had been or would be ranked #1 in the world, including Stan Smith, Ilie Năstase (twice), Björn Borg, John McEnroe (three times), Ivan Lendl, Mats Wilander, Boris Becker, and Andre Agassi. Other notable victories over top players include wins over Guillermo Vilas(career high #2) and Vitas Gerulaitis (career high #3), as well as Adriano Panatta (career high #4), Pat Cash (career high #4), and Harold Solomon (career high #5).

Golden Set

Scanlon achieved a golden set against Marcos Hocevar of Brazil in the first round of the WCT Gold Coast Classic at Delray Beach, Florida on February 22, 1983. Scanlon won the match, 6–2, 6–0.^[2] A golden set is when a player wins the set without losing a single point. The feat is recorded in the Guinness Book of World Records.
