Suzy played about four tournaments in 2007 and then nothing for nearly nine years but has been playing fairly regularly this year and apparently improving rapidly.
If she's been a full time tennis and fitness coach for the past years, I doubt her tennis has improved rapidly over the past few months. And I presume she's been playing league and money tournament tennis for ages. But obviously there will be some ITF level experience etc. that she's lacking.
Whatever she's been doing she's not doing too badly for someone lacking ITF experience. Two QFs and a final looks OK to me. She also doesn't seem to buckle under pressure either. A welcome addition.
