Querrey leads their previous meetings 3-1. Their last match was In April this year. Querrey won in straight sets in Houston on clay. He has won their last 3. The other 2 wins were on hard courts ( one indoors). Becker’s win was back in 2006 on an indoor hard court.
Both players have a game that should be ideal on grass. Becker reached the final in 2014 but has been struggling on this surface since then.
Querrey has had the better results in the last 2 seasons on grass and I favour him to take a tight match. I’m not happy backing below 1.65
