Cal Ripken made his debut on August 10, 1981. He had no plate appearances but scored the winning run. In the bottom of the 12th, Ken Singleton doubled against Kansas City Royals pitcher Renie Martin. Cal Ripken came in to pinch run. After an intentional walk to Eddie Murray, designated hitter John Lowenstein drove a walk-off RBI single to right field. The Orioles beat the Royals 3-2.
The Trading Card Database has over 12,000 cards listed for Cal Ripken. Finding a card that wasn't made of him is nearly impossible. Nobody would expect a late season call-up to have a card in that season's set. Then again, no list of Orioles greats would be complete without Cal Ripken. So I cheated. Just a little.
