Struggled last night too. His groundstrokes aren't as sharp as what we've become accustomed to.I don't think he has a prayer on a hard court at this point, but the guy is a champion and I wouldn't be shocked if he had one more run in him anywhere.
Although he struggled in his last match, I always like Medvedev on hard courts and Fritz has really shown signs of life lately.
I'm just not a huge believer in Carlos, but he's definitely dynamic and I can't believe in Sasha until he gives me a reason to.
Carlos is a guy that can kill the elite players in the world when on and lose to a guy outside top 50 when he's not. He's a lot more federer strategically than the djokovic/nadal way he's always attacking.
