The 2001 Tennis Masters Cup was a men's
tennis tournament played on
indoor hard courts. It was the 32nd edition of the
year-end singles championships and was part of the
2001 ATP Tour. The tournament was held at the
Sydney Superdome in
Sydney, Australia from 12 November through 18 November 2001. The doubles competition was set to take place in
Bangalore, India but was cancelled because of security fears following the
September 11 attacks. A competition was held in early 2002, but it did not provide any ranking points and was held as the ATP World Doubles Challenge Cup.
Lleyton Hewitt won the singles title.[2]
