If Novak plays like against Querrey before he started tanking, than Novak in 2, something like 6-2, 6-3.
He might not even need it. On current form, Querrey is probably a more dangerous rival than Jo. I expect JWT to miss every other return and pile up a gazillion errors.
Can't see him manage to stay in rallies with Novak at all, unless he randomly picks up form, in which case he could even win the match, but it's hard to see such scenario unfold; Novak should get his first indoor win over Tsonga.
