For topspin backhands, Feliciano Lopez uses a grip extremely close to
Continental, turned a tiny bit toward the
Modified Eastern. The Continental grip is not well suited to hitting topspin, and Feliciano hits relatively few topspins. Feliciano's Continental grip would work better for slice, but he turns his grip halfway toward the Eastern forehand grip for slices. Feliciano used to have a major weakness on the backhand side, where he couldn't reliably hit a decent topspin, but that weakness is less glaring recently, as his topspin backhand has improved.
