Donaldson has won both their previous meetings. Their last match was in April last year on American clay. He won in straight sets. The other was also in America but on a hard court and again was won in straight sets.
Donaldson lost to Mannarino in the qualifying rounds. He has been doing
well on clay this year. I think Harrison is favourite due to Donaldson losing in the qualies but he probably knew he had the lucky loser place and didn’t give 100%.
Harrison is usually weak on clay but has had a couple of decent wins in recent weeks over Tomic and Garcia Lopez. When I say decent I mean for someone who is poor on clay.
Value is on Donaldson. He should take at least a set and has a great chance to win.
The sets will be tight. Lay Harrison below 1.65
