This challenge rule is stupid.
Watching Lisicki, good serve, no chance her opponent could return, she tried and failed. But feckface said it was out, challenged it and the feckface was wrong. Replay the point? Eh? IMO the opponent had no play on it.
Again 40-30 down Lisicki serving, she smashes a forehand cross court which the oppo isn't getting, feckface calls it out, challenge, it's in... replay point? Eh? There was no fecking possible play on it so why replay? It's surely her point?
Anyways, her oppo then won the replayed point which gave her the break. Stupid rulings and shit linespeople make this sport infuriating.
