Head to heads are 2-2. Their last match was in February 2016 on clay. Delbonis won in 3 sets. All their matches were on clay.
Delbonis has never won a match at Wimbledon in 3 visits. He has improved his hard court game this year and I think we will start to see better grass results from him too.
Fognini is consistently average at Wimbledon for a player of his ability. He reached the 2nd round last year.
We have some value on Delbonis here. Fognini has been distracted from his tennis since he got married.
Fognini starts around 1.38 and a lay below 1.30 looks a good plan.
