This quiz tests your memory of everyone who played for the Pirates during the 1979 season. Last names only are permitted. The positions listed are via Baseball Reference. (Link not provided, only because you shouldn't be clicking it right now.) I did some research on the exact roles of the three PH/PR guys, but in any case, the key there is that they didn't play in the field at all.
The quiz doesn't just include members of the Pirates' World Series roster, but literally everyone who played. Fortunately, there were fewer in-season moves back then -- the 1979 Bucs used 34 players, compared to 49 for the 2013 team and 45 in 2014.
