American rising star Tommy Paul didn't drop a single point on his serve during the first set of his Winnetka Challenger quarter-final match on Thursday. The American won 7-of-7 of his first serve points and 5-of-5 of his second serve points and converted 3-of-6 of his break point chances on his way to clinching a dominant 6-1 first set win over Australian Dayne Kelly.
World No. 393 Kelly didn't give up after a disappointing first set as he won the match in the end 1-6 7-6 (5) 6-2. World No. 195 Paul's serve efficiency dropped in the second and third set. The American won 25-of-37 of his first serve points and 11-of-20 of his second serve points during the second set.
Then in the decider, the 21-year-old won just 10-of-19 of his first serve points and 6-of-13 of his second serve points. More interestingly, 2015 French Open boys' singles champion Paul won more points than Kelly after two hours and 11 minutes of action.
The American won a total of 102 points, while 27-year-old Kelly won a total of 100 points during the match. Paul was playing at the Winnetka Challenger for the second straight year. The 21-year-old reached the semi-final in his debut appearance at the tournament last year.
The American fell just short of making back-to-back Winnetka semi-finals. Meanwhile, Kelly -- who was playing the Winnetka main draw for the first time in his career -- lost to world No. 355 Evgeny Karlovskiy in the semi-final.
