OK let's just do Brasier. Maybe this will clarify what I'm talking about.
In 2018 Brasier had 0 saves, 10 holds and 2 blown saves.
In 2019 Brasier has 6 saves, 2 holds and 2 blown saves.
Now here's the important part:
3 of those 'blown saves' occurred when he entered the game in the 7th inning.
Only 1 of his blown saves occurred when he entered the game in the 9th.
Now do you see the issue?
