List of second-generation Major League Baseball players


The following is a list of father-and-son combinations who have played or managed in Major League Baseball.

Third-generation families

In 1992, Bret Boone became the first third-generation MLB player.
Altogether, there have been five third-generation MLB-player families:
There have been four third-generation families affiliated with MLB in roles other than player:
In 2017, the Boone family was on the verge of becoming the first family to have produced four generations of players who reached the major leagues: Ray, Bob, Bob's sons, Aaron and Bret, and Bret's son, Jake, who was selected by the Washington Nationals in the 38th round of the 2017 MLB Draft. However, Jake did not sign and is currently not a professional as he instead plays for Princeton University. Because he is attending college, he will not be eligible for the draft or to sign a professional contract until 2020. More recently, the Bell family, consisting of Gus, Buddy, and Buddy's sons, David and Mike, is poised to become the first fourth-generation family. Mike's son, Luke, was selected by the Arizona Diamondbacks in the 34th round of the 2019 MLB Draft. Mike is currently the vice president of player development for the Diamondbacks.
Whether any of the Boones or Bells see their great-grandson play in the majors, they will not represent the first great-grandfather/great-grandson combo in MLB history. In 1985, Bill Wilkinson made his big-league debut with the Seattle Mariners; his great-grandfather was Jim Bluejacket, who played for Brooklyn in the Federal League in 1914-15 and for the Cincinnati Reds in 1916.
The MacPhail family is the first family to have four generations affiliated with Major League Baseball in roles other than as players. Larry was the general manager of the Reds and Dodgers as well as the president, general manager, and co-owner of the Yankees. Larry's son, Lee, was president and general manager of the Orioles, executive vice president and general manager of the Yankees, and president of the American League. Larry and Lee are also the only father and son pair to have been inducted into the Baseball Hall of Fame. As an executive with the Reading Phillies of the Eastern League, until his untimely death at age 27 in an automobile accident in 1969, Lee MacPhail III secured the MacPhail family's baseball legacy as being the first to have had three generations of family members involved in baseball. Lee II's other son, Andy, is the current president of the Phillies and was previously general manager of the Twins, president and chief executive officer of the Cubs, and president of baseball operations for the Orioles. Lee MacPhail III's son, Lee MacPhail IV, has been the director of scouting for the Indians, Expos, Nationals, and Orioles. With Lee MacPhail IV's appointments, the MacPhail family's legacy extended to a fourth generation of family members involved in baseball.
