6. Jon Dowd
Video Game: MVP Baseball 2005 (2004)
Hands down the best replacement character in baseball video game history. Jon Dowd was slugging outfielder for the San Francisco Giants who was only there because Barry Bonds had withdrawn from the MLBPA licensing agreement.
Unlike Barry, Dowd was a righty. While that resulted in far fewer moon shots into Digital McCovey Cove, Dowd was even better than Bonds. He could routinely smash gargantuan homers to left and center, much like his real-world counterpart, but with far more frequency-100 round-trippers in a season was not out of the question.
