We got a few baseball cards of Bob Horner in a Cardinals uniform as an added bonus. A bunch of them were made in 1989, the year after he was a Cardinal, but a few card companies managed to squeeze him into their 1988 sets.
The Topps Traded set was one of two Topps sets that year with a Horner card.
Horner was out of shape by the time he joined the Cardinals, and not a very good player. The card does a pretty good job of hiding the fact that Horner was a little pudgy and not very good as a player during his brief tenure with the Cardinals. He only hit 3 home runs in 200 at bats in St. Louis. I tried to track down a highlight of Horner wearing a Cardinals uniform, and the best I could come up with was him getting out of the way while Vince Coleman is stealing home.
That's it. Bob Horner as a Cardinal. Here is the back of the card.
He was really a good player while he was with the Braves, it's too bad that his time with the Cardinals did not go a little bit better. In retrospect though, the Cardinals probably would not have ended up with Pedro Guerrero if Horner had done anything during his time with the team.
