Sometimes you're just stopped in your tracks, or in your thoughts, at the sheer self-belief that tennis pros have.
Consider the case of one Sorana Cirstea, who won her first WTA-level title at age 18, and last week, her second—at age 31.
In simple math, the Bucharest-born slugger went 12 years and 6 months between seizing those titles. That makes her notching of the 2021 WTA title in Istanbul the third-longest "wilderness" run of all time, behind those of Mirjana Luciuc-Baroni (16 years, 4 months) and Kimiko Date (13 years, 1 month).
The far more complicated math has played out in hundreds of practice sessions and match settings, and certainly between her ears. Over those 46 months, she went without winning hardware, and likewise without claiming the psychological software that helps one manufacture the belief to keep putting in the work.
