Emma Raducanu is searching for a new coach after splitting with Vladimir Platenik after an unsuccessful two-week trial.
The British No 2 reached the second round of the Miami Open on Wednesday with a comfortable straight-sets victory over Japan's Sayaka Ishii.
However, she did so without Platenik, with Raducanu's spokesperson saying: "Emma and Vlado have parted ways.
"Emma has utmost respect for Vlado and the work they started but it wasn't quite heading in the right direction.
"Emma is now focused on doing as well as she can here in Miami after her a solid start today and will continue looking for the right coach."
