If Haas plays like he did in Shanghai, I don't think Delpo can take him down just serveboting....
Delpo completely owns Haas and Tipsarevic (possible finalists). H2H vs the two of them: 6-0 combined, 13-0 in sets, best each of them managed was one 5-7 set, combined they broke JMDP's serve twice in 13 sets.
3 more aces for Brands
This will be tough if the guy's serve doesn't cool down a bit.
