Former World No. 4 Kei Nishikori appears to be on his way to a full recovery from the wrist injury he suffered last August after claiming his first ATP title since winning the Memphis Open in 2016.
Nishikori, who dropped to No. 27 after a five-month injury layoff, defeated American Mackenzie McDonald on Saturday to win the RBC Tennis Championships, an ATP Challenger Tour event in Dallas.
The 28-year-old said he felt uncomfortable during the first three matches, but lost just one set in his five-match title climb and seemed to improve every day.
