People on the old board gave me shit about nominating Starocci as the next likely 4 timer, particularly when he was just a RS FR, but I'll do it again:
If they RS Mirasola this year, he's going to be an absolute terror for the next four years. Askren has coached him up very well but he's still pretty raw in some positions. I expect to see some gigantic leaps from what we saw at OTTs and U20 WTTs to his RS FR year. He's going to be rolling with Cael, Varner, Brooks and Snyder on the regular.
