Matches to Watch, Day 5
Ivo Karlovic (CRO) vs Roger Federer (SUI) 
Roger and his aching back should be well-rested after his second-round walkover. He’ll need a strong back to keep up with Karlovic’s scary ass serve—the biggest serve in the game. I saw Karlovic in person last year at Indian Wells and let me tell you, this dude is HUGE. He’s also eminently beatable since, other than his serve, he doesn’t have the greatest game—and certainly not compared to Federer. Like John Isner, Karlovic succeeds mostly because he’s difficult to break. But Federer is too good.
Prediction: Federer in straights
Alexandr Dolgopolov (UKR)  vs Bernard Tomic (AUS)
The two most fascinating, most entertaining up-and-comers in the game right now (with Milos Raonic not far behind). Dolgopolov has been agonizingly inconsistent thus far, going five sets in both of his previous matches. Tomic has had his erratic moments too, but I think he’s feeling the buzz of being a hometown favorite to push him. Watch for wild swings in both players’ favor, but ultimately Tomic’s craftiness will win out.
Prediction: Tomic in five
John Isner (USA)  vs Feliciano Lopez (ESP) 
The last American man standing! If only I liked his one-dimensional game more. Lopez will be a bigger challenge than Nalbandian was (which is saying something, because Nalbandian was a challenge!), but the longer the match goes, the more I think Isner will pound Lopez into submission.
Prediction: Isner in four
Anabel Medina Garrigues (ESP)  vs Li Na (CHN) 
Caroline Wozniacki (DEN)  vs Monica Niculescu (ROU) 
Kim Clijsters (BEL)  vs Daniela Hantuchova (SVK) 
The already unpredictable women’s draw is only going to get more unprectable with each passing day—and we’re not even into the second week! Li, Wozniacki, and Clijsters are all favorites to win today, and to go deep in the tournament. Neither Li nor Wozniacki are the picture of consistency, and Clijsters is playing injured. At least one of these women is going to be upset tonight. Getting my dartboard out to decide who it will be…
Predictions: Li in straights; Niculescu in three; Clijsters in three
