William Neil Scanlon[2] (November 13, 1956 – June 2, 2021) was a tennis player from the United States, who won seven singles and two doubles titles during his 13-year professional career.

[1] 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.

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.

He defeated Henrik Sundström, Chris Lewis, Pat Cash, John McEnroe, and Mark Dickson, before losing to Jimmy Connors.

During his career, Scanlon would log wins over eight players who had been or would be ranked #1 in the world, namely Stan Smith, Ilie Năstase (twice), Björn Borg, John McEnroe (three times), Ivan Lendl, Mats Wilander, Boris Becker, and Andre Agassi.

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 also authored the book Bad News for McEnroe: Blood, Sweat, and Backhands with John, Jimmy, Ilie, Ivan, Bjorn, and Vitas in 2004 as a tribute to the era during which he participated on the ATP International Tour.
