Fatigue

Joe Page takes the mound
He gets 4 batters out but
Walks 3
4 singles
2 doubles
5 homeruns

When Hal finally goes out to the mound to take him out of the game, Page says, "Why are you removing me? I still feel great. I still am a F9."

Well if he wasn't going deep in the count before giving up those HRs might not be tired yet.
What was the pitch count?

He threw 72 pitches, most of which were waste high, right down the middle.
