You'd think Nalbandian would be atleast a slight favourite considering he just beat Tips last week. Could be a close one but I'm leaning Tips here. I just think he comes out much more motivated in this Tour than he was last week. And if he can serve well and hold, Nalbandian will likely have one of his mini-meltdowns which Tips will need to take adv of and finish this in 2.
nalbandian should match up well here, he can return hard serves very well and he played well last week. you have to consider the ranking, thats why line is even
Also take into account that Tipsarevic is a well known party boy and loves the scene in Miami. I think his desire is higher this week than last and he's got the points to defend this week vs. last week in Indian Wells where all he needed was one win to equal the year before.
we'll see how it goes, but i think nalbandian's level right now is top 6 in the world if you disregard his fitness which shouldnt be too much of an issue yet and tipsarevic just doesnt play his max right now
