I gotta believe Tug McGraw of the 1980 World Champion Philadelphia Phillies. Here is a decent shot of him. In the early 1980's Tug wrote a comic strip about a pitcher called Scroogie. One of the characters in the strip was called Homer. A rookie slugger who hit 59 home runs but did not hit 60 because of home run 59 was lost and he got really worried about that little ball and went into a slump. There was little a bit of foresight as Homer resembled a slugger who would come on the seen a couple of years later. His name Mark McGwire. Mark bared an uncanny resembalance to Homer and he also smashed a lot of Homers as a rookie too.
