(Reuters) - World number four Sofia Kenin has parted ways with her coach - her father, Alex Kenin - after a string of disappointing performances this year, the 22-year-old American announced on Instagram on Friday.

"This was not an easy decision for me as we shared many great moments together and had a lot of success," wrote Kenin, who won her maiden Grand Slam at the Australian Open in 2020.
