1. Harry Frazee – Boston Red Sox (1917-1923)
No MLB owner has inflicted more lasting damage on a franchise than Harry Frazee. After purchasing the Red Sox following their 1916 World Series victory, Frazee systematically dismantled the team to fund his Broadway productions. His most infamous move was selling Babe Ruth to the Yankees for $100,000, but he didn’t stop there. Over five years, he traded 17 top players to New York, accepting inferior talent and cash in return. The “Curse of the Bambino” that followed lasted 86 years until Boston’s 2004 World Series victory.
2. Andrew Freedman – New York Giants (1895-1902)
Freedman was the most despised owner of baseball’s monopolistic National League era. During his seven-year reign, he went through 14 managers, blacklisted critical reporters, and fought constantly with players. His political connections through Tammany Hall enabled him to sabotage competitors by manipulating subway line construction and road planning. He nearly destroyed the reserve clause in a dispute with pitcher Amos Rusie and attempted to transform the NL into an eight-team syndicate that would heavily favor his Giants.
3. Jeffrey Loria – Montreal Expos/Miami Marlins (1999-2017)
Loria’s tenure was marked by destruction and deception across two franchises. He effectively killed baseball in Montreal through mismanagement before taking over the Marlins. In Miami, he perfected the cycle of developing stars only to trade them away when due for raises. Despite claiming poverty, the Marlins were highly profitable. He convinced taxpayers to fund a $2.4 billion stadium deal, then dismantled a promising team after one season. Loria finally sold the Marlins in 2017 for $1.2 billion – a billion more than his purchase price.
4. William Cox – Philadelphia Phillies (1943)
Cox managed to get banned from baseball after just one year of ownership. The 33-year-old Yale graduate constantly meddled in team operations, making midnight calls to manager Bucky Harris and forcing unwanted changes on players. When Harris was fired, he revealed Cox’s gambling on Phillies games to Commissioner Landis. Though Cox claimed he only bet on his team to win, his 64-90 Phillies proved this was both illegal and foolish. Cox sold the team and was banned for life.
5. Gerry Nugent – Philadelphia Phillies (1933-42)
A former shoe salesman, Nugent inherited the Phillies through his wife’s connection to the previous owner. His decade of ownership was marked by constant losing, averaging 100 losses per year and just 2,750 fans per game. Financial troubles forced him to repeatedly sell his best players, including Hall of Famer Chuck Klein. After back-to-back seasons of 111 and 109 losses, Nugent was forced to sell in 1943, possibly preventing Bill Veeck from making history by integrating baseball.
6. Tom Werner – San Diego Padres (1990-94)
The TV producer’s brief ownership was marked by controversy and fan alienation. Werner’s 1993 fire sale of stars like Fred McGriff and Gary Sheffield led to a lawsuit from season ticket holders who claimed fraud. His tenure was also marked by the infamous Roseanne Barr national anthem performance that outraged fans. Werner sold in 1994, but later found redemption as part of the ownership group that brought multiple World Series titles to Boston.
7. Bob Short – Senators/Rangers (1969-1974)
Short’s tenure was marked by destructive decisions across two cities. After moving the Lakers to Los Angeles, he bought the Senators and quickly alienated Washington fans by threatening relocation. He moved the team to Texas in 1971, prompting fans to riot in the final DC game. In Arlington, he continued making poor decisions, most notably rushing 18-year-old David Clyde to the majors, effectively ruining the prospect’s career for short-term ticket sales.
8. Emil Fuchs – Boston Braves (1923-35)
A former lawyer for Black Sox scandal financier Arnold Rothstein, Fuchs led the Braves to consistent failure. He even appointed himself manager in 1929, losing 98 games while displaying little understanding of baseball strategy. Desperate and $300,000 in debt by 1935, he signed an aging Babe Ruth as a publicity stunt. The team finished 38-115 that year, the worst record in modern National League history, forcing Fuchs to sell.
9. George Argyros – Seattle Mariners (1981-89)
The California real estate developer was unpopular from the start in Seattle. Operating as an absentee owner, Argyros broke promises to spend on talent, instead trading away stars and posting nine straight losing seasons. He constantly fought with local officials over the Kingdome lease and threatened relocation. Despite his poor stewardship, Argyros still profited handsomely, selling the team for $77 million – six times what he paid for it.
10. CBS – New York Yankees (1964-73)
The media giant’s ownership marked a low point in Yankees history. CBS inherited an aging roster and couldn’t adapt to baseball’s new amateur draft system. The team suffered its first losing season in 40 years and was regularly outdrawn by the Mets. When broadcaster Red Barber showed empty stadium shots during a game, CBS fired him. They sold to George Steinbrenner in 1973 for $10 million – $3 million less than their purchase price, a rare instance of an MLB team selling at a loss.
