Most Grand Slams in MLB History

Alex Rodriguez holds the MLB record for the most career grand slams, with 25 hit across his 22-year career from 1994 to 2016. He passed Lou Gehrig, whose total of 23 had stood as baseball’s benchmark for more than seven decades.

A grand slam is a home run struck with the bases loaded, scoring four runs on a single swing, and it is the single most valuable play in the sport. Hitting them in bulk requires both elite power and a knack for coming up with the bases full, which is why the all-time leaders are among baseball’s greatest run producers. Here is the full leaderboard of career grand slam leaders, and the context behind the numbers. All figures are through the 2025 season.

The record holder: Alex Rodriguez and 25 slams

Rodriguez spent his career in the heart of powerful lineups, first in Seattle and Texas and then with the New York Yankees, where runners were frequently on base ahead of him. That setting, combined with 696 career home runs, produced a steady stream of grand slams and eventually the all-time record of 25.

He broke Gehrig’s mark in 2013, ending one of the longest-standing records in the sport. The two-slam cushion he built is modest, but with no active player anywhere close, it has proven durable.

The full leaderboard of career grand slams

The table below ranks MLB’s all-time career grand slam leaders.

Rank	Grand slams	Player	Career
1	25	Alex Rodriguez	1994-2016
2	23	Lou Gehrig	1923-1939
3	21	Manny Ramirez	1993-2011
4	19	Eddie Murray	1977-1997
5	18	Willie McCovey	1959-1980
5	18	Robin Ventura	1989-2004
7	17	Jimmie Foxx	1925-1945
7	17	Ted Williams	1939-1960
9	16	Hank Aaron	1954-1976
9	16	Dave Kingman	1971-1986

The list mixes all-time greats such as Gehrig, Aaron, Foxx and Williams with power specialists like Robin Ventura and Dave Kingman, showing that the record rewards a specific blend of pop and opportunity.

Lou Gehrig and a record that stood for generations

Lou Gehrig’s 23 grand slams anchored the top of this list from the 1930s until 2013. He hit them in fewer games than the modern leaders and did so while batting behind Babe Ruth in the Yankees’ famous lineup, which regularly loaded the bases ahead of him. That his record survived more than 70 years underscores how difficult the feat is to accumulate.

The middle-of-the-order sluggers

Manny Ramirez (21) and Eddie Murray (19) were classic run producers who spent decades hitting cleanup, exactly the profile that generates bases-loaded chances. Robin Ventura’s 18 slams, meanwhile, included a famous stretch of clutch hitting for a player better known for his glove.

Why the record matters

Grand slams combine baseball’s biggest swing with its most valuable outcome, four runs at once, so leading the sport in them marks a hitter as both powerful and reliably clutch.

The short version: Alex Rodriguez holds the MLB grand slam record with 25, ahead of Lou Gehrig (23) and Manny Ramirez (21). As of the 2025 season, no active hitter is close, keeping A-Rod’s mark firmly at the top of the list.
