Last year's NCAA singles champion Peyton Stearns made her Top 100 debut on Monday, moving up 27 spots from No.116 to No.89, the biggest jump this week among the Top 100.

In just her fifth career WTA main-draw appearance, Stearns advanced to her first WTA singles final in Bogota last week. The three-time All-American at the University of Texas finished as runner-up to defending champion Tatjana Maria in a three-set final.
