Developed over months and months of research and development in collaboration with Grigor Dimitrov, the new 97S edition of this classic frame has been adapted for greater spin potential.

With an 18×17 string pattern, it allows you to produce spin in a way that emphasises precision and feel. The ability to maintain accuracy when taking the ball early is absolutely vital in today’s game, and that's exactly what the 97S provides.

Weighing in at 310g with an unstrung balance of 335mm, it offers a slightly more all-round option compared to other rackets in the Pro Staff family.

Our friends at Pro-Direct want one lucky reader to get a taste of what Grigor Dimitrov is so excited about so they've donated one Wilson Pro Staff 97S for us to give away.
