American John Isner edged out Kevin Anderson in three tie-break sets to win a 'Battle of the Giant's final of the Atlanta Open.
In a contest between the top two seeds, Isner needed two hours and 54 minutes to wear down his opponent 6-7 (3/7) 7-6 (7/2) 7-6 (7/2) .
This hard court encounter did not yield a single break of serve, although the South African Anderson failed to convert any of his 11 chances - seven of these break point opportunities coming in the deciding set.
Anderson also held two championship points in the 11th game of the final set but was unable to take advantage of either.
On the first Isner sent down an unreturnable 143-mph serve, with Anderson nudging a backhand long on the next.
In a battle between two big servers, Isner sent down 24 aces to 21 from his opponent.
The win provided the American with his second ATP Tour title of 2013, and seventh of his career.
Incidentally, the match was reportedly the tallest final in ATP Tour history with Isner standing at six-feet 10-inches, two inches higher than Anderson.
It was also Isner's third Atlanta final following defeats in 2010 and 2011.
