Thought I'd start a thread devoted to up-and-coming players who might one day become the next Big Four. We're all aware of people like Coric, Chung and Zverev. There are one or two others to watch out for as well.
Someone who's just wandered across my radar is Taylor Fritz, a 17-y-o American who's leaping up the rankings. He won the Fairfield Challenger last week, beating some big names, all in straights, like Smyczek, Kavcic, Blaz Rola and then Dustin Brown in the final. In fact, he's on a hot streak of 16 straight wins and won the US Open juniors. He jumps over 100 places to 232.
Looks like Sampras, talks like him, plays like him. Ugh.
Another one to watch out for is Andrey Rublev, who's also 17 and gave Anderson a hard time in the first round of the US Open. He's currently ranked 179.
I think tennis is skipping a generation, in terms of top talent. I think these guys, plus possibly Kokkinakis, Elias Ymer, Jared Donaldson and one or two others, could do big things. I'm reserving judgement on Nick the Dick until he decides to take the sport seriously.
Anybody else we should watch out for?
