Source-derived summary

The Association of Tennis Professionals (ATP) World Tour is the elite professional tennis circuit organised by the ATP. The 2009 ATP World Tour calendar comprises the Grand Slam tournaments (supervised by the International Tennis Federation (ITF)), the ATP World Tour Masters 1000, the ATP World Tour 500 series, the ATP World Tour 250 series, the ATP World Team Championship, the Davis Cup (organized by the ITF), and the ATP World Tour Finals. Also included in the 2009 calendar is the Hopman Cup, which does not distribute ranking points, and is organised by the ITF.

Tour changes

The ATP reinstated the world tour to its name as the organisation rebranded itself as the ATP World Tour. ATP World Tour tournaments in 2009 are classified as ATP World Tour Masters 1000, ATP World Tour 500, and ATP World Tour 250. Broadly speaking the Tennis Masters Series tournaments became the new Masters 1000 level and ATP International Series Gold and ATP International Series events became ATP 500 level and 250 level events.

The World Tour Masters 1000 includes tournaments at Indian Wells, Miami, Monte Carlo, Rome, Madrid, Toronto/Montreal, Cincinnati, Shanghai, and Paris. The end-of-year event, the Tour Finals, moved to London. Hamburg has been displaced by the new clay court event at Madrid, which is a new combined men's and women's tournament, and the indoor hard court event in Madrid was replaced by an outdoor hard court Masters tournament in Shanghai. From 2011, Rome and Cincinnati will also be combined tournaments. Severe sanctions will be placed on top players skipping the Masters 1000 series events, unless medical proof is presented. Plans to eliminate Monte Carlo and Hamburg as Masters Series events led to controversy and protests from players as well as organisers.

Editorial analysis

Why this record matters

“2009 ATP World Tour” is worth following because a concise public description often conceals a longer documentary argument. Here, World, Tour and tennis provides the most credible route into that argument.

Evidence profile

The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Aug 20, 2026. The linked authority identifier is Q300011. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2009, 1000 and 2011.

Critical limits

Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it

Use the entry as an orientation point, then follow its citations and revision history. Names, dates and institutional relationships should be checked against the original record.
