Here's the opening of a minor sports page article in the L.A. Times about the Dodgers facing 49-year-old Colorado Rockies starting pitcher Jamie Moyer:
To prepare to face Jamie Moyer on Friday night, Dodgers outfielder Tony Gwynn Jr. could watch videos of his past at-bats against the Colorado Rockies left-hander.
Or he could talk to his father, Hall of Famer Tony Gwynn Sr., who also faced him.
Rookie Scott Van Slyke could also solicit advice from his father, former All-Star Andy Van Slyke.
Shortstop Dee Gordon's father, former pitcher Tom Gordon, was Moyer's teammate. ...
"I think Jamie pitched against my grandfather," joked Jerry Hairston Jr., a third-generation major leaguer.
So, four of the 25 Dodgers are the sons of former major leaguers. And these aren't minor major leaguers, either. All four dads spent at least 13 years in The Show.
When I was a kid, it was quite rare for big leaguers to be the sons of big leaguers. It seemed more common for baseball players to be brothers than father-son combos. I first noticed a sizable number of scions in baseball about 20 years ago. Adam Bellow wrote a book early in the last decade, In Praise of Nepotism, that toted up the statistics showing growing dynasticism in many fields, but I haven't looked at the numbers much since. Is this trend still growing in the baseball?
