After collapsing on January 11th following a workout, John Olerud underwent brain surgery for the removal of an aneurysm on February 27, 1989. Olerud, a left-handed first baseman at Washington State University, went on to be the Blue Jays’ third round pick in the June Amateur Draft.

I remember him wearing a batting helmet even while playing first. Thought it strange until I heard about the surgery.
Good player. Thanks for reminding me of him.

Same for me. He did make the helmet look good, though.
