Sara Bejlek

Sara Bejlek, a 20-year-old left-hander from Czechia, enters the court at No. 29 with 1,652 points and a 71 percent win rate this season, including 10 wins against just four losses. Watch how the lefty spin jumps off the forehand side, bending rallies into awkward positions for right-handed opponents. Her balance is notable: the swing looks short and compact, but the ball comes through heavy, not flat. That combination sends first-time viewers reaching for the replay button more than expected.

Twelve career titles at age 20 hint at a player who finds ways to close, not just strike. On TV, note how she moves after contact, recovering to the center hash rather than staying wide to admire the shot. The edge is less in power, more in reshuffling the court to her own rhythm. Expect looping crosscourts followed by sudden, sharp angles down the line, played aright when she is on time.
