I'm sure you can come up with your definition of "high round" and figure this out for yourself.
Heck you can decide to include the pitchers the Astros drafted when he was working for them if you like.
My definition of high round would be...top 3 rounds maybe?
In which case:
2019-0 (8th round)
2020-0 (5th round)
2021-0 (5th round)
2022-0 (5th round)
