There is Cecil Cooper, Carl Crawford and Coco Crisp. Lesser knowns, Clay Carroll, Chris Carpenter, Chien-Ming Chang, Carmelo Castillo and Casey Cox. I could have also been a homer and just used a Chicago Cubs team photo or even non-players with cards like Charles A Comisky or former President Calvin Coolidge.
No, instead I went with a "star" from the early seventies, billed a "the next Willie Mays" by Leo Durocher in 1972 (then the manage of the Houston Astros). A supreme talent who burst onto the big league circuit at the age of 19; a rocket of an arm, blazing speed, a solid glove and a bit of pop in his bat. Five time Gold Glove winner, four time all-star and had 20 HR's and 50 stolen bases three consecutive years (1972, 73, 74).
While he never lived up to that super-stardom label (nobody else has managed to do that either), Cesar Cedeno was a very good player; career numbers of 199 HR's, .285 BA and 550 SB. Mostly known for hs days in an Astros uniform (1970-81) but also played for the Cincinnati Reds (1982-85), St Louis Cardinals (1985) and finished his career with the Los Angeles Dodger (1986). Historian Bill James ranks Cedeno as the 21st best center-fielder of all time.
I found a quote from The Baseball Page written by Dan Holmes and Kirk Robinson that best summarizes Cedeno: " A talented player in the mold of Willie Mays, Cesar Cedeno never reached superstar status for many reasons, some beyond his control. The Dominican-born Cedeno was involved in a scandalous off-the-field episode that resulted in the death of his girlfriend; played much of his career for a team that rarely made headlines above the Oklahoma border; suffered from playing in the Astrodome, a stadium that cost him power numbers that may have gave him notoriety; and finally, injuries and attitude problems cost him playing time. Despite all of that, Cedeno had a very good career, winning five Gold Gloves and finishing among league leaders in steals, batting average, and doubles on many occasions. "
