Andy Roddick believes the Grand Slam race between the big three is too hard to predict, but he says it is 'crazy' what Rafael Nadal is achieving this season.
Nadal had to pull out of Wimbledon with an abdomen tear on Thursday ahead of the semi-finals, but he is still having a special year.
He won both the Australian Open and French Open with a foot injury, and he was looking like a real contender to win Wimbledon too.
His two Majors this year have put him ahead of rivals Roger Federer and Novak Djokovic in the Grand Slam race, but former world number one and US Open champion Roddick still thinks it's too close to call.
"I was one of the guys who said, there's no way Rafa can play as hard and as physical as he does and last past 30, so dummy me," Roddick told the Kasich and Klepper Podcast. "He's still winning Slams this year. He is at 22 now.
"I hate to say this cuz he's one of my favourites, but I don't see how Roger gets back into full flight after what he's gone through with multiple knee surgeries at 40 years old.
"I think he's probably gonna stick at 20, you know, and, and we'll see how it plays out with Novak.
"When you're deported from Australia, they have to approve you coming back. Otherwise you have, you're like kicked outta the country for a couple years.
"So we don't know if he's gonna be able to play the next two slams.
"So I don't know how to predict this mess. It's certainly weird when, when real life kind of infringes on our little, our little tennis bubble, but, you know, it's crazy what Rafa's doing right now with maybe like one foot limping to 14 Roland-Garros titles. "It's just crazy."
After withdrawing from Wimbledon, Rafael Nadal said that he still expects to be fit to play the US Open later this year.
