He's probably this year's Ferrer. Doubt he'll win a single match there.
Ouch. Harsh. Depends on who else is in his group. And remember - Ferrer made the final in 2007 in Shanghai. He got schooled by Roger in the final but that's beside the point.
Seriously...Thiem ends up in a group with - let's say Roger, Goffin and Dimitrov? The Goffin and Dimitrov matches are a toss up. He ends up in a group with Nadal (or Roger), Cilic and Zverev? Hell no he's not winning a match...
