Another early exist for Sascha brewing. This kid needs to get his act together. As a pretty good all-court player he should be reaching the QF or better at most Slams. Still inconsistent and tempestuous, but I suppose he is only 21.
.
I'm not all that convinced Zverev is a future Major winner, TBH. Sure he's talented, and won Masters, but the mental implosion at the Slams, losing to journeyman players with no outstanding weapons in early rounds is developing into a pattern that could be hard to break. He's almost frozen with fear and unravels in the ugliest way possible.
Lendl his current coach had a hard time winning Majors at first, but he was making Finals and SF's until his breakthrough in his 4th final beating Mac at the French Open.
Even players who did reach a Finals earlier in their career , Tsonga, Baghdattis, couldn't do it again. For now I'd be happy if Sasha made a Semifnals anywhere..
There is no reason to believe Sasha's contemporaries aren't going to get more competitive so it's not even a given he's going to be the top Nextgen player.by next year.
It's one thing to get blown off the court by a red hot player, instead he seems to play down to the level of his opponent. I mean, we're talking Kohlschreiber who hadn't won against a top player in years. Kohlschreiber!
Not wishing him ill, but I just dont' think it's a slam dunk we're talking a future champ.
