Horrible matchup for Tipsy. Like Nishikori or Haas (players with similar H2H vs JMDP), he doesn't possess the defensive skills required to trouble/beat Del Potro.
Not this nonsense again. We've been over this already. Haas had valid reasons for playing poorly against Del Potro in every one of his encounters. It has nothing to do with match up contrasts.
