250 and 500 Series
The International Series for men is split into two categories, both run by the ATP: the 250 Series and 500 Series. Like the Masters 1000, these events offer various amounts of prize money, and some regular International Series events offer larger prize monies than 500 Series tournaments. The Barclays Dubai Tennis Championships offer the largest financial incentive to players, with total prize money of US$1,426,000.
Challenger Tour and Futures Tournaments
The Challenger Tour for men is the lowest level of tournament administered by the ATP. It is composed of roughly 160 events and, as a result, features a more diverse range of countries hosting events. The majority of players use the Challenger Series to work their way up the rankings, including World No. 1s Pete Sampras, Marcelo Ríos, Patrick Rafter, and Gustavo Kuerten. Andre Agassi, between winning Grand Slam tournaments, plummeted to World No. 141 and used Challenger Series events for match experience and to progress back up the rankings. The Challenger Series offers prize funds of between US$25,000 and US$150,000.
