He has a 50% chance of beating Russell. He has a 1% chance of beating Anderson.
Also, did you notice he's playing doubles with Harrison? I did not expect that to happen.
I'd give him more than a 50% chance to beat Russell. They're 2-2 in the h2h but Don beat him last time they played and Russell's last win was a ret., not to mention the approx 10 yr age difference. I'd put DY as the favorite against Russell.
I'd also give DY a shot against Anderson. DY is 3-5 against Anderson, with Anderson winning the last 5, but pretty much all of their matches have been close, 3 sets, or 2 close sets.
At some pt he's gonna have to capitalize on one of these draws he's been getting and get to a semi or final.
