    Ji Sung Nam Player Overview

    Ji Sung Nam came through qualifying at the Shanghai Challenger with two consecutive wins, though his overall form is less consistent: just 4 wins from his last 10 matches. Even so, he tends to accumulate a decent number of games even in defeats - averaging 19.4 games per match. His hold percentage stands at 64%, with points won on serve at 48%. Over this same stretch, Ji Sung Nam has also shown reasonable break-point conversion (38%) and rarely loses without a set - in only six of those ten matches - which reduces the risk of a one-sided outcome even against a favourite.
