Lleyton Hewitt‘s former management, Octagon, has taken him to court for breach of contracts, and he’s fighting back with a countersuit, citing incompetence and deception on the part of the agency.

And while we feel bad that Lleyton can’t catch a break (he received a wildcard to play at Delray Beach this week. and lost. on his birthday.), it’s always interesting to get a look at what happens to the $60 I fork over for nosebleed seats.

In 2005 and 2006, Hewitt earned $6.75 million net in endorsements and appearance guarantees — including $3.5 mil from Nike and $2.3 mil from Yonex. He also received $340,000 in appearance fees for Sydney, Adelaide, and Queen’s Club.

Octagon wants a piece of this pie in the sky, but whether the agency was still representing Hewitt for those two years is in question.

Meanwhile, Hewitt’s smarting because of a 2002 legal scuffle with the ATP that could’ve been smoothed over by Octagon. After declining a on-camera interview as part of promoting the 2002 U.S. Open, Lleyton got slapped with a $100k+ fine. The ATP considered the interview compulsory; Hewitt thought he’d already fulfilled all his obligations. He spent another $100,000 only to have the ATP decision upheld, albeit with a much smaller ($20,000) fine.

Let’s hope he doesn’t bleed too much more money settling all these matters — he doesn’t have a lot of tennis-playing years left!
