This morning (our time), Ben Shelton beat Aslan Karatsev to win the Tokyo tournament, his first career tournament title. When the new rankings come out tomorrow, he'll be No. 14 in the world, in a dead heat with Frances Tiafoe and closing fast on the current top Americans, No. 10 Taylor Fritz and No. 12 Tommy Paul (who Shelton beat in Tokyo).
Since the beginning of the U.S. Open, Shelton is 14-2 with two victories over Paul and one over fourth-ranked Jannik Sinner. His only losses were to Djoker in the Open semifinals and a three-setter (in a best-of-three, with two tiebreaks) to Sebastian Korda (who BTW, has risen to No. 23 in the rankings) in the Shanghai quarters.
Next up for Shelton is the ATP 500 event in Vienna next week, where he got a crappy draw -- he'll play Sinner in the first round. That said, I'm sure Sinner is thinking he got a crappy draw as the No. 2 seed (Medvedev is the top seed). Should be a great match.
