I'm thinking that Isner wins it. Both have big serves and rarely get broke and John is usually money in tiebreakers. Anyone else thinking about makin a play on this match?

[AbleFollow]

isner is very bad on his second serve now. Karlovic is in his mind. So my choice is Karlovic

[michalis]

well, they are both players with similar style, they are tall and because of that they draw heavily on their dominant serve

but isner moves a lot better than karlovic around the court, he is in better form than karlovic and he has the crowds support

i will consider it a major upset if isner does not win but it is a possibility

Coin flip. Probably comes down to nerves in a tie break. I would say Isner can do more if his serve isn't working, but that doesn't help against a big server if Ivo is on.

2 tiebreaks.

The best play for this match is OVER , im gonna take it - over 25,5 100$, can win 185$

Two giants on the court today .................. Standing at 6'9" and 6'10". I'll go with the American giant in this one.

Both players have not dropped their serve this week, Isner losing 1 set in a tiebreaker. Karlovic serving twice as more Aces as Isner is this week. Isner getting 75% first serves in this week and winning 80% of first serves, while Karlovic getting 70% first serves in and winning 86% of his first serves. Isner's second serve is slightly betting 62 as opposed to 58.

Isner has killed opponents on their second serve winning 56% of those points. I love Isner but am going with Karlovic here.

Over is a sucker bet in this one I feel. I think one of them wins this in 2 and I don't think it's two tie breaks. Took a small piece of action at +105 on Under 25.5.

Isner really improved this year.

[michalis]

??? didnt you see him last year at the us open?

[EaglesPhan36]

Under, Boo Yah.

I like Isner myself, small play
