Learner Tien came out swinging at Indian Wells on Thursday, battling past Adam Walton in two tie-breaks in his opening match at the ATP Masters 1000 event, 7-6 (3), 7-6 (8).
His victory over the Australian was a special one, as it was the milestone 50th tour-level win of his career.
And it gets even more special.
At just 20 years old, Tien is the youngest American man to achieve 50 career tour-level wins since Andy Roddick, who was 19 when he hit that number at the 2002 Australian Open.
YOUNGEST U.S. MEN TO RECORD 50 WINS SINCE 2000 (tour-level):
- 19 years & 4 months: Andy Roddick [at '02 Australian Open]
- 20 years & 3 months: Learner Tien [at '26 Indian Wells]
- 20 years & 5 months: Alex Michelsen [at '25 Delray Beach]
- 20 years & 10 months: Sam Querrey [at '08 US Open]
- 20 years & 11 months: Taylor Fritz [at '18 Basel]
(Note: the ATP website lists Tien as having 48 career wins coming into Indian Wells, but due to a glitch his semifinal win from the 2024 Next Gen ATP Finals is missing from that total, and it's 49—see today's ATP media notes for correct stats)
