I will be on Azarenka in this match. Makarova has been impressive this year but traditionally she's not as strong of a hard court player. This year she's been really good (26-9). Vika is 13-5 which is about the same win rate, but career-wise Vika is a much better hard court player. Plus, Vika has looked better this tourney and played tougher competition IMO. Sure, Makarova's win over Bouchard was good but Bouchard was clearly hurting all match and she gave Makarova all she could handle.
Vika -130 3 units for me. I would endorse o22 as well. probably put a unit or two on that myself.
