Shepherd (b. 1960) played in the majors from 1984 to 1986 for the Blue Jays. He had 18 hits, 2 home runs and a .167 batting average.
I'm looking to scrape together some more money to buy a few more cards off of Marty, so I can keep pushing this set toward completion. I know that Ricky Wright (and Dick Howser and Roy Lee Jackson) will keep this out of reach, but I'm going to keep trying.
