If you want to say Paxton and Sale are fragile, fine. They are. Both have a history of long spells on the IL. Duvall had a freak injury this season, but he has been on the IL a lot, so he could be considered fragile.
If Devers pulls a hammy today and has to be sat on the IL for 10 or 15 days, is he fragile too?
It's pro sports, players get hurt, sometimes in weird ways.
Chang had a freak injury; he has no history of time on the injured list. As near as I can tell, the last time he might have been on it was his rookie year in 2019. Hamate bone injuries can take a long time to heal.
Ditto McGuire. Freak injury, but one that has happened to many players. Again, a guy with no real injury history.
