I believe her coach before this one lasted 1.5 yrs.Random question for anyone who happens to know... Marin is Miki's longest lasting coach since...? I really don't think she was working this long with someone in a while (not that it's terribly surprising, but still).
I honestly thought that her recent coaching arrangements didn't last that long, but your memory is probably way better than mineI believe her coach before this one lasted 1.5 yrs.
He started in Mid 2015 and lasted through 2016.
I remember he was working with her before Wimbledon 2015 when she played Bencic at Birmingham.
Before that Prpric lasted almost 2 yrs. Fall 2012-Spring 2014.
