Every fall, baseball heroes are born under the bright lights of October. For a select few families, those moments of postseason glory have stretched across generations.
When Vladimir Guerrero Jr. homered for the Blue Jays against the Yankees in Game 1 of the 2025 American League Division Series, he and his Hall of Fame dad joined an exclusive club of father-son duos to go deep in the playoffs.
Here’s a look at all six father-son duos to do it. (The year each duo joined the list is noted in parentheses.)
Vladimir Guerrero and Vladimir Guerrero Jr. (2025)
The Guerreros have already secured their place among baseball’s legendary father-son duos, but their shared legacy continues to grow. The latest chapter came in the 2025 ALDS, as the younger Guerrero crushed his first career playoff homer with a solo shot in Game 1 before adding a grand slam in Game 2.
Twenty-one years prior, Vlad Sr. got a chance to experience postseason baseball for the first time as a member of the Angels, fresh off a 2004 regular season that would win him AL MVP honors. While the Angels were swept by the Red Sox in the ALDS that year, Guerrero still left his mark on the series with a game-tying grand slam to right-center field in the seventh inning of Game 3 at Fenway Park, the first of two playoff home runs in his Hall of Fame career.
The Guerreros collectively are one-of-one in this regard: No other father-son pairing features multiple players with a postseason grand slam.
Cecil Fielder and Prince Fielder (2008)
The Fielders were both imposing sluggers in their day, each finishing with exactly 319 home runs in the regular season and logging multiple top 3 finishes in the MVP voting. Both also recorded multiple playoff homers.
Cecil hit all three of his postseason dingers during an impressive October run with the Yankees in 1996, producing a .308 average and 14 RBIs to go with his trio of home runs as New York won it all. Prince finished his playoff career with a batting average below the Mendoza Line but managed to swat five home runs in October.
Tony Perez and Eduardo Perez (2002)
A cornerstone of Cincinnati’s “Big Red Machine,” Tony Perez helped the Reds dominate the NL during the 1970s, a period that would come to define his Hall of Fame career. Perez hit five postseason home runs for the Reds, who won four pennants and two World Series titles from 1970-76.
The younger Perez is known more for his broadcasting exploits, but he did carve out a 13-year playing career that saw him join his father in the postseason home run column. His lone playoff blast came as a pinch-hitter for the Cardinals in Game 2 of the 2002 NLDS, marking his only postseason hit in six plate appearances.
Julian Javier and Stan Javier (2001)
The Javiers are easily the most unlikely pairing on this list. Neither was known for power -- Julian hit 78 home runs over 13 seasons in the Majors, while Stan went deep just 57 times in 17 big league campaigns -- but each managed to homer once in the playoffs.
Stan’s lone postseason dinger came in one of the final games of his career -- as a 37-year-old for the Mariners in Game 2 of the 2001 ALCS against the Yankees, 34 years after his father hit a three-run home run for the Cardinals to blow open Game 7 of the 1967 World Series against the Red Sox.
Bob Boone and Bret Boone (1995) / Aaron Boone (2003)
Of course the Boones are on this list -- the family is a baseball dynasty, producing four big leaguers over three generations. While Ray Boone logged only one plate appearance in the postseason, striking out as a pinch-hitter against future Hall of Famer Warren Spahn in the 1948 World Series, his son Bob was an October fixture for the Phillies and later the Angels in the late ’70s and early ’80s. Bob finished his career with a .311 average and two homers over 36 playoff games, winning a World Series with Philadelphia in 1980.
Two of Bob’s sons, Bret and Aaron, also enjoyed lengthy big league careers that afforded them an opportunity to shine on the postseason stage. Bob and Bret became the first father-son duo in history to homer in the postseason when Bret hammered his first playoff dinger (one of three in his career) for the Reds in Game 3 of the 1995 NLDS. The Boones made the list again in 2003, when Aaron produced one of the most iconic blasts in postseason history: a pennant-clinching, walk-off homer for the Yankees (the team he currently manages) in Game 7 of the ALCS against the rival Red Sox.
