Goffin leads their previous meetings 5-3. They last met in May 2016 at the French Open. Thiem won in 4 sets. Their most recent hard court match was at the Australian Open last season. Goffin won that one in 4 sets. Two of Thiem’s wins were on clay and the other was due to retirement.
Thiem has played 4 sets in all his matches so far. In the last round Paire had 17 break points and converted 5 of them. Struff had 10 break chances in their first round match though only took 2 of them.
Goffin struggled in the first round and needed 5 sets to beat American Reilly Opelka. Opelka is outside the top 200. Since then Goffin has been impressive beating Stepanek and Karlovic in straight sets. Stepanek only broke him once and Karlovic didn’t even get a break point.
Hard court stats for the last 12 months favour Goffin. I am on Goffin from the start
