The Indianapolis Tennis Championships was an annual men's tennis tournament played in Indianapolis as part of the ATP Tour.
Originally known as the U.S. Men's Claycourt Championships, the event was created after the Indianapolis Sports Center decided to resurface its 18 clay courts with Deco-Turf II, the same surface as the US Open.
As a consequence, the U.S. Men's Clay Court Championships was moved from Indianapolis to Charleston, South Carolina.
[1] The tournament's change in surface and name came with a change of date to be closer to the start of the US Open.
The event gained the attention of the world's best players and became a premier warm-up stop for the US Open.
