Sony Ericsson Open Miami Masters
The Miami Masters is an annual tennis tournament for men and women held at Key Biscayne, in Miami-Dade County, Florida. The event's current sponsored name is the Sony Ericsson Open. The event is part of the ATP Masters Series on the men's tour and is a Tier 1 event on the women's tour. The tournament is played on hard courts. The event is currently held in March each year.
The tournament is widely regarded as the most prestigious on the ATP and WTA tours, and was given the nickname "Fifth Grand Slam". Its importance is reflected by the WTA's decision to designate it a mandatory event, like the 4 Grand Slam tournaments. The tournament was founded by former player Butch Buchholz and took place for the first time in February 1985 at Laver's International Tennis Resort at Delray Beach, Florida and in Boca Raton the following year. Since 1987 the Sony Ericsson Open found their permanent home at Key Biscayne.
