Just saw a video of that on Youtube and it's the dirtiest thing I've ever seen in a match, rolling a ball intentionally on court in order to prevent the opponent from getting a point, and that at 14-11 in tie-break. Velasco's misbehavior was the result of an emotional match with questionable referee calls, but what Renan did was purely disgusting
I dont know which misbehaviour is worse. This one by Renan or when a macedonian player pulled down the net in a match against Hungary for the ECH qualies.
Anyway, I do think that only one day of suspension is such a shame It is absolutely not compared to what Velasco did.
If the sanction for this is so light, well, it shouldnt surprise us we could see this kind of behaviour again.
