I agree that we need character in sports, but i'd take Robredo's reaction in defeat rather than Zhang Jike's reaction in victory...
(For the history, Robredo lost his second consecutive final to Murray, having blown away 5 match points in each!)
As for those who say that Serena broke her racket and nothing happened to her, i thing there's a difference..
Tennis players break their rackets in frustration, blaming themselves mostly, while Zhang Jike had a "you didn't think i could win but i won and you can all **** off" kinda attitude. Obviously there was a lot of pressure on him, but i think it was an overreaction there.
Then the Ittf overreacted themselves, not necessarily by the amount of the fine, but by relating the fine with the winnings of the tournament, which is plainly wrong. Either disqualify the guy and give first place and prize money to Ma Long (that would be totally unacceptable in my opinion), or grant him first place prize, then issue him a fine and a carefully worded warning (that is the course of action i think should be taken).
Anyway, i think that with the importance that the Chinese are giving to respect and honour, Zhang Jike will face a more severe punishment from within the CNT, something that we may never hear about.
