Liudmila Samsonova and Marta Kostyuk meet in the quarterfinal at Guadalajara on Thursday. Marta Kostyuk comes in at 7 wins from the last ten. Liudmila Samsonova has won 6 of the last 10.

Marta Kostyuk simply rates much higher on hard, and our number follows from it. Expect resistance, but the match-level math tilts clearly toward Kostyuk.
