I Honestly Believe Teenagers will Start winning titles in 2015
Between Coric, Garin, Khachanov and Quinzi, I believe this group of kids will have what it takes to win AT LEAST a 250 event before they turn 20.
Quinzi will be ranked 307 by next week.
Coric will be ranked 367 by next week.
Garin will be ranked 383 by next week.
Khachanov (having only played 5 events this year) will be ranked 442.
Next year they should all be winning challengers, and playing ATP events and grand slam qualies, the year after I predict at least one of them will win a 250.
