Tiago Torres

Tiago Torres has climbed 245 spots this season while playing just one week of tour-level tennis, and the ATP No. 427 he now holds, first reached Tuesday, is a career high. The week itself was a 2-1 run on home clay at the Estoril Open, the 24-year-old Portuguese taking straight-set wins over Nikoloz Basilashvili and Alejandro Tabilo.

He banked four sets without dropping one, but Hugo Gaston ended the week 6-3, 6-4 in Friday's quarterfinal. The constant was his return game: 44.2 percent of return points won and 52.6 percent of break points converted across the three matches.
