I'm very happy to hear Clay Warrior's serve is clocking in the 120's. And a 136 to boot? Very nice. He needs to keep that going. He'll need it at Wimbledon.
He usually plays very different in these events, hitting more freely because he's got no pressure. That's why he doesn't waste time between points and hits flatter forehands.
I've always liked to watch his matches at Queens because of this reason.
