Yup. Incidentally, if he were to lose it the day after the US Open, his run would end one week shy of tying Connors for #4 for most weeks at #1, and three weeks shy of tying Lendl for #3. It's unlikely. But it could happen.Novak is mathematically guaranteed for 267 weeks. I think this puts him at #1 until September 2nd. He could lose it at the end of the USO if Nadal or Federer go on epic runs and he does absolutely nothing.
From there he just has to outperform Nadal and Federer for the remainder of the year. Fed would likely NEED to win the US Open, which he hasn't done since 2008, and Nadal rarely plays the schedule after the USO. Nole is in a good position to get the number 1 by this time next year. If he doesn't get it with this current stint of number 1, he will likely only need 40 or so weeks for the remainder of his career.
Seems likely to get it
