Flip-Flop (* 2,422)

According to Betting Zone:

favouritism changed an incredible 2,422 times on Betfair during the course of the longest match in tennis history between John Isner and Nicolas Mahut, which finally came to an end on Thursday.

After 11 hours and five minutes on Court 18 and with a raft of records having been broken, 23rd seed Isner found two crucial winners to break the resistance of the Frenchman in the 138th game of an astonishing set.

The pair first walked on court on Tuesday, and Isner - who hit 112 aces in the match - secured a 6-4 3-6 6-7 (7/9) 7-6 (7/3) 70-68 triumph to bring the curtain down on one of the most remarkable episodes in the history of the All England Club.

Betfair spokesman Tony Calvin said: "Betting guru John McCririck loves to say 'flip-flopping favourites' when the market moves in horse racing, but even that motormouth would have been rendered speechless at this incredible match.

"The odds changed in the blink of an eye."

Meanwhile William Hill offer 10/1 that Wimbledon will introduce a fifth set tie-break before the 2011 tournament as a result of that mammoth encounter.

Some of us can remember reading their Dad's newspaper at the breakfast table, and the report of the record set in 1969, when the 5 hours 12 minutes match between Pancho Gonzales and Charles Pasarell (22-24, 1-6, 16-14, 6-3, 11-9) seemed amazing.
