Two-time grand slam champion Naomi Osaka has parted ways with her coach Jermaine Jenkins within a span of 7 months after her defeat in the 4th round of the US Open. Osaka hired Jenkins after she won the Australian Open. Jermaine Jenkins has also been the on-court practice partner with seven-time Grand Slam champion Venus Williams. Naomi Osaka has not reached a tournament final since she partnered up with Jenkins after abruptly ending her association with Sascha Bajin. Osaka posted a tweet that said she was grateful for the time invested and the things she learned on and off-court. She further added that it was the right time for her to embark on a new path.
