Reverse Penhold Backhand Angle

I've recently started using the penhold grip and I can't seem to return balls without sidespin. What should the angle of the bat be so that I can get pure topspin?

Hi Romeo,

This is an awkward part of the stroke.  See if you can get the bat facing directly to where you want the ball to go.  This will allow you to get pure topspin.  It si an awkward angle to get your wrist into.  Relax your wrist and you can also slightly shift your finger position to allow the bat to face the right direction.
