Janice Tjen vs Martina Okalova prediction
Janice Tjen lived up to the hype as she downed Leolia Jeanjean to reach the round of 16.
The 23-year-old raced to a 6-3 6-3 success over the seventh seed to post just a second tour-level win of the year.
The Filipino star now takes on qualifier Martina Okalova after the world number 464 defeated Australia’s Arina Rodionova 7-5 6-4.
The Slovakian is enjoying her run in Sao Paulo on the back of some poor form of late, but may find the task of upsetting the attack-minded world 130 a hurdle too far.
Indeed, Tjen has won 14 of her last 16 matches (across all levels) and the 23-year-old looks like a player destined to crack the top 100 in the not-too-distant future.
