I was always a guy that would give the closer the top of the 9th in a tie game at home, but I feel like the 10th is that place under the new Manfred rules with the runner on.
Michael gave up 11 ER in 51 IP before he hurt his knee.
He's given up 18 ER in 22 IP since.
Probably some sort of correlation, but I'm no mathemagician
