highest singles ranking ever at #6 and his highest doubles ranking
at #189. He won titles in New Delhi,
Paris-Bercy Open and
Stockholm Open in the course of the year
and although he was #9 at the end of the year, he played in the ATP
Tour World Championship, replacing an injured Andre Agassi. There
he defeated Boris Becker in straight sets but did not advance to the
semifinal round. Although Thomas preferred to stay focused on his
singles game, he fine-tuned it with some doubles play. He and Jim
Courier finished the year ranked #162 as a team and Thomas'
individual doubles ranking was #357. Thomas this year posted
victories over world No. 1 Pete Sampras, Wimbledon champion Richard
Krajicek and French champion Yevgeny Kafelnikov.
