I just finished watching the match, I think Piroddu will remember this for a while, he gave up two takedowns both of them on his own attack. he could easily score on both but instead he gave up points ! I think the first action was definitely a 2 and not 4. cuz the action started on the ground. that wasn't a 4pts throw. and the last action was also just one point pushout . that was no way a takedown. they used to penalize these kind of actions as fleeing with 2pts + caution but if I'm not wrong the new rules say 1pts + caution ! (they change the rules day to day so even for me it's hard to be up to date about the rules ) but I didn't understand what happened after the challenge , they removed the caution and gave the challenge thing back to the Italian coach !! if their challenge was wrong (which it was) they should gave another point to the Uzbek guy.
and yeah success in cadet level doesn't necessarily mean success in Junior/Senior levels. specially in Greco because Greco is less technical. but this kid has the talent, i believe he has a Greco background, he needs more experience in freestyle competition to not lose the single leg twice. this semifinal was his match to lose.
