At age 15, Isabelle Lacy (born 2006) is very well thought of by the LTA and has now zoomed into the adult WTA rankings, at WR 1182, with 11 points, after coming through qualis at the ITF 100k at Surbiton.

A tall, slender girl, with good arm speed, nice technique, and a back-of-the-court game that gets good penetration, there's a lot to like in her game. Comes from Surrey, I believe.
