Karolina Pliskova is a Czech right-hander who reached the world No. 1 ranking on the strength of one of the biggest serves in the women's game. She reached the final of the US Open and, years later, the final of Wimbledon, and won numerous WTA Tour titles across a long, consistent career. Her height and clean, efficient technique made her a particularly difficult opponent on fast courts throughout more than a decade near the top of the sport.
