Do you think there will ever be another teenage/early twenties slam winner? The last one able to do this was Del Potro in 2009, and after him there's been nobody able to accomplish this feat. Federer was only 21/22 when he won Wimbledon, so he was relatively young, too. Then there's Safin and Hewitt. Michael Chang, too. Will there be another player, like Nadal in the future, who just comes out with an early slam win? Thoughts?
