Ryan Harrison has announced Michael Russell as his new coach.
The 25-year-old has made a few coaching changes in recent years, and will now be working with the former ATP player in what is his first coaching position on tour.
Excited to announce that next year @MRusselltennis and I will be working together. His reputation on and off the court are flawless and I look forward to getting to work. Also would like to thank the @usta for their support. American Tennis is ready to rock in 2018! #usa #tennis— Ryan Harrison (@ryanharrison92) December 5, 2017
"His reputation on and off the court are flawless and I look forward to getting to work," said Harrison.
This season has been the best of Harrison's career so far, and includes his first tour title at Memphis, a French Open victory in doubles, and reaching a career-high of No. 40 in singles. Harrison also married longtime girlfriend Lauren McHale, fellow pro Christina McHale's sister, following his win at Memphis.
Harrison is No. 47 in the rankings.
Naomi Osaka has also made a change to her team. She brought on Sascha Bajin, the coach announced.
Bajin was working with Caroline Wozniacki for most of this season as an assistant coach and hitting partner, having previously had a similar role with Victoria Azarenka and a long association with Serena Williams.

Bajin did not specify whether he has joined Osaka as a coach or a hitting partner.
Osaka reached a career-high of No. 40 in 2016 but despite a couple of top ten wins this season, the hard-hitting 20-year-old slid below No. 60 in the rankings. She is coached by David Taylor, a veteran Australian coach.
Wozniacki will not get another full-time hitting partner, but will instead work with various hitting partners in different locations.
