Learner Tien is 18 years old, has a record of 53-9 this year, which now includes a total of 7 titles, including his third challenger title on Sunday in Fairfield, California.

We had a chat on Monday before the tournament had begun in full, and then we spoke again AFTER he won the title in 39 minutes and 07 seconds, 6-0, 6-1 over Bernard Tomic. Record setting on that one, becoming the shortest completed Challenger Final in history.

We talk about goals, THAT winning streak, and much more.
