Hearing @Steve_Weissman mention Coric's junior slam title inspired a Wikipedia deep dive so...

Here's a thread of the QFists + results for the US Open Boys Junior Singles events from '03-'17. Rated them by strength of the field + pro results + intrigue. Fun Facts also included

2003: An indisputable Top 15 All-Time Men's player (Murray), 2 GS finalists (Baghdatis/Tsonga), a top 10 dubs player (Mergea) + Dudi and Baker

Scoville Jenkins = USTA legend, so +1 for intrigue

Rating: 9/10

2004: An indisputable Top 15 All-Time Men's player (Murray), 2 Top 15 guys (Troicki, Querrey), 3 Top 50 guys (Stakhovsky, Beck, Zverev)

2016: Tsitsipas, FAA already Top 10/20, Kecmanovic inside the Top 50

- What a semifinal crew!!!! +2
- FAA was...(checks notes)...16 years old during this event!!!! +1
- Most of these players are still REALLY young, so it's hard to judge their pro success right now

Rating: 7/10

Some Takeaways:
- Not a new thought, but Junior Slam success DOES NOT guarantee success in the pros
- Fascinating to see who the top juniors were from '05-'12, and how many failed to crack the Top 100 in either singles or doubles during their pro careers
- Scoville Jenkins

- Many of the #NextGenATP guys leading the way (Zverev, Coric, Tsitsipas, etc) WERE top juniors as well, and perhaps why that's why so many tennis fans (myself included) are so excited about their upside
- My personal favorite is '15, but '03, '13, and '14 were all excellent

- Too early to judge the '17-'19 US Opens and the event's participants, though 2018 champ Thiago Seyboth Wild has already won an ATP Singles Title
- Understandable, but crushing not to have this event this year
