Jordan Spieth missed the cut at the Deutsche Bank Championship on Saturday, but he's still got a very good chance to wake up on Tuesday ranked No. 1 in the world.
Spieth, who lost the No. 1 spot to Rory McIlroy after missing the cut last week at The Barclays, can regain the top ranking if two things happen:
1. Jason Day doesn't win the Deutsche Bank Championship, and
2. Rory McIlroy finishes worse than solo 10th place.
At the halfway point of the tournament, Day is six shots behind 36-hole leader Charley Hoffman, and McIlroy is tied for 59 at 2 over par, 14 shots behind Hoffman.
Of course, Day can make up the six shots and win, in which case there is no way Spieth can become No. 1 in the world. If McIlroy finishes inside the top 10 and Day doesn't win at TPC Boston, then he'll remain the top-ranked player in the world.
