Judging by Nole's results here so far, it seems to me he has created quite the intimidating factor for the rest of the players. I think Nadal has been the most intimidating player of this era but the tide may have just turned in Nole's favour. Though he's still somewhat vulnerable against Murray and to some lesser extent Federer, and perhaps even with Nadal, he still seems to be the player to beat. Though on clay, it's still Nadal since he doesn't lack any confidence on this surface regardless and Nole has yet to win RG, so Nadal is definitely the man to beat.
Sampras used to say, it's not about only beating your opponents, it's also about sending a message to them and Nole is sure sending a message right now as he goes 6-0, 3-1 up against Busta.
Busta finally holds a service game and marks his place on the scoreboard. He should get a cookie for this achievement.
