Burleson decided to tweak McGwire’s stance and focus him on hitting for a higher average. Other factors such as poorer training and personal problems contributed, but McGwire never found a comfortable stance and hit .201 with 22 homers in ’91. (A substantially bulkier and stronger McGwire, returning to his original stance, would later hit for much higher averages while boosting both his home run and walk totals.).
Funny thing here is the seasons being mentioned are 1989-1991.
1989 OBP: .339
1990 OBP: .370
1991 OBP: .330
So if his OBP in 1989 was considered "high" by this guy, this "awful" season in 1991 wasn't that far away even though his BA went down, which is a meaningless stat anyway.
