Young is up against Mayer (the other Mayer) who is a clay courter so this is a very winnable match. On the other hand just last week he wasn't able to finish off Chardy in the second set tiebreak and promptly collapsed in the third. I think a similar thing might happen here, where Young goes up a set but then Mayer realizes that he really doesn't want to lose to this guy and pulls it out in 3.
