This has got to some sort of record. 10 DC wins in a year. Anybody has the numbers on this?
Ljubicic had 11 wins and 1 loss in 2005, all in live rubbers. He nearly finished the year with a pefect 12-0 record until he lost his second singles match in the final against Hrbaty. He pretty much single handedly helped Croatia beat the USA (with wins against Agassi, the Bryan brothers and Roddick
), Romania and Russia to get to the final against the Slovak Republic that year, where he won his first singles match and the doubles rubber with Ancic.
McEnroe did have a perfect 12-0 record in 1982, although 3 of his wins came in meaningless dead rubbers that year.
