Oh, I am eating this card up with a spoon. Dennis Martinez has one of the best smiles in baseball, but there weren't a whole lot of cards from his time with the Orioles that showed off that smile. Maybe that's poor photo selection from the card companies, or maybe he was actually smiling less, as he was dealing with an alcohol addiction at the time. Either way, I'm glad to see "El Presidente" flashing a mischievous grin here. The cherry on top is the bat-and-helmet pose, which you don't get to see on a lot of pitcher cards, especially for American League teams between the beginning of the Designated Hitter era (1973) and the inception of Interleague Play (1997). It's clear that Dennis and/or the Fleer photographer decided to have a little fun, especially since the stadium in the background looks to be Fenway Park (Fleer did most of their work in Boston in those days). It's unlikely that Earl Weaver was auditioning the Nicarauguan hurler as a pinch hitter. Of course with Earl, you never know!
Incidentally, on this date in 1981, Dennis pitched 8 and 1/3 innings, holding Texas to three runs on seven hits and outlasting Fergie Jenkins for a 7-3 Orioles win. Now you know.
