MASON, Ohio – Juan Martin del Potro rallied after losing the second set to roll past qualifier Dmitry Tursunov 6-4, 3-6, 6-1 Friday and reach the semifinals of the Western & Southern Open.

Del Potro responded by breaking Tursunov in the second game of the third set on his way to a 3-0 lead. Another break gave del Potro a 5-1 lead, and he clinched the win with an ace at love.
