Harvey pitched in 47 games in '87...but only 5 innings? I have to start looking at these stats more closely, that's the third error I've seen in this set.
That's bizarre. It's the 5 IP that is correct. He appeared in 3 games, not 47.
Here are the guys appearing in 47 games in 1987. Matt Young and Dan Quisenberry have cards in this set. I wonder if they were using the typeset from one of those cards and accidentally forgot to change the number for games in 1987.
