He was a starter until 2017, then the Brewers moved him to the pen. And in both scenarios he only threw 13 pitches an inning in both those games, so it's not impossible that a reliever could last that long....realistically would that happen, probably not, but OOTP doesn't make you stretch guys out like they would in real life. I would me more mad that my team was so impatient that he was able to go that long. I bet if you had shelled him in both games, you would not have posted anything.
