Joe, Joe Jr. and Casey Coleman
Pitcher Casey Coleman made his debut at 23 last season with the Chicago Cubs. While his pitching performance was forgettable -- three earned runs over 4.1 innings in a loss -- his debut will go down in baseball history. He is the first third-generation pitcher to play in MLB. His father, Joe, was an All-Star who won 142 games with seven teams from 1965 to '79. His grandfather, also named Joe, was an All-Star pitcher who threw in the big leagues for 14 seasons.
