Insights

All four wins came in 2017-2020

Sugita’s 4-17 Grand Slam record is entirely built on a four-year stretch: his only victories came in 2017, 2018, and 2020, with no wins recorded in 2014-2016 or 2019-2021. That means every match win in the data sits inside a relatively narrow mid-career window.

His peak result was reached three times, all at the Australian Open

His best Grand Slam result is R64, and it appears only three times: Australian Open 2018, Australian Open 2020, and Australian Open 2020. No other tournament in the table shows a better finish than R64.

Wimbledon was his most frequent stage, but not his best one

He played Wimbledon five times, more than any other Slam in the table, yet his Wimbledon results were mostly R128, with only two R64 runs in 2017. By contrast, the Australian Open produced his best finishes despite fewer appearances.

He peaked in match wins at age 28

His strongest season by results was 2017, when he won two matches and reached R64 twice, both at age 28. No other year in the table matches that combination of multiple wins and multiple R64 finishes.

His Slam career ended with a three-event R128 run at age 32

The final three entries are the 2021 Australian Open, Wimbledon, and US Open, and all ended in R128 at age 32. That closing sequence contrasts sharply with the earlier R64 results and shows a clear late-career drop-off.
