The Pick: Daniil Medvedev vs. Alexander Zverev, Turin ATP Finals Championship
Medvedev has Zverev's number, and should win this match based on that metric, but defeating a quality opponent three times in two weeks still poses a massive challenge.
Djokovic enters the semifinal round as a three-game favorite over Zverev.
With four wins (three on clay) and no losses to Ruud, it sure seems like this match is Rublev's for the taking.
Betting dead rubbers might not be the smartest move, but Medvedev is not one to let his opponents off easy, and tends to play his best tennis in front of a hostile crowd.
Expect some nervy and competitive tennis as both players fight to keep their hopes alive in Turin.
Zverev will need to dig extremely deep in order to avoid a fifth-straight loss to the world No. 2.
Rublev is in the midst of a cold-streak, while Tsitsipas is battling an elbow injury, making this one a tough match to predict.
