Anthony Rendon: Angels’ $245M Third Base Black Hole (2020)
After helping the Nationals win the 2019 World Series, Rendon seemed like a can’t-miss signing for the desperate Angels. Four years later, he’s played just 200 games, battling everything from hip surgery to shin splints while collecting nearly $38.5 million annually. Add the fact that he’s gone on the record as saying he only views the game as a “job,” and he’s added insult to the fans to his injuries.
Pablo Sandoval’s $95M Boston Belly-Flop (2015)
The “Kung Fu Panda” arrived in Boston with three World Series rings and departed with a .237 batting average and endless jokes about his expanding waistline. The Red Sox essentially paid $95 million to watch Sandoval’s belt size grow larger than his on-base percentage, finally cutting him loose in 2017 while still owing him $48 million. How bad was it? His lasting Beantown memory was of the Panda breaking his belt when swinging at a pitch.
Carl Pavano: The Yankees’ $40M Mirage (2004)
Dubbed “American Idle” by the New York Post, Pavano made just 26 starts over four years in pinstripes, earning roughly $1.5 million per start. His injury list read like a medical textbook: bruised buttocks, broken ribs from a car crash, and various arm troubles. The Yankees essentially paid him to occupy their training room.
Mike Hampton’s Mile-High Meltdown (2001)
The Rockies gave Hampton $121 million, supposedly because he loved Colorado’s school system — an excuse that Mets fans still laugh at to this day. Two years and a 5.75 ERA later, Hampton and his education-minded family were headed to Atlanta. His contract became such a hot potato that it took three teams to figure out who’d pay for this Rocky Mountain disaster.
Albert Pujols: Angels’ $240M Prayer Goes Unanswered (2012)
The Angels thought they were getting the second coming of Babe Ruth. Instead, they got a declining slugger whose batting average dropped faster than a California mudslide. While Pujols did hit his 600th homer in Anaheim, the Angels never won a playoff game during his tenure, eventually eating $30 million just to make him disappear.
Jacoby Ellsbury: The $153M Yankee Ghost (2014)
The Yankees thought they were stealing Boston’s centerfield star. Instead, they got baseball’s most expensive ghost, as Ellsbury spent more time on the injured list than on the field. He missed his entire final two seasons with mysterious ailments, leading to an ugly contract dispute that perfectly capped this $153 million catastrophe.
Josh Hamilton’s Los Angeles Angels Disaster (2012)
The Angels gambled $125 million on Hamilton’s troubled past staying in the past. Two years later, they were paying him to play for their division rival Rangers after his relapse and subsequent public spat with owner Arte Moreno. The saga served as a sobering reminder that some risks aren’t worth taking, no matter the potential reward.
Barry Zito’s Giant-Sized Disappointment (2007)
The Giants made Zito baseball’s highest-paid pitcher with a $126 million deal, expecting the former Cy Young winner to bring his Oakland magic across the bay. Instead, the lefty provided seven years of mediocrity, including a 63-80 record and 4.62 ERA. His lone bright spot came in the 2012 playoffs, when he posted a 2-0 record and a sparkling 1.69 ERA, but even that could not justify the massive investment.
Prince Fielder’s Detroit Dream Gone Wrong (2012)
When the Tigers signed Fielder to a nine-year, $214 million contract, they thought they had the slugger who could anchor their lineup for a long time. Two years later, they were paying the Rangers to take him off their hands. A career-ending neck injury in 2016 turned this deal into an insurance claim, with Detroit still paying for their prince who never became king.
Kevin Brown: Baseball’s First $100M Bust (1999)
Brown made history as baseball’s first $100 million man, but the Dodgers soon wished they could turn back the clock. Between injuries, declining performance, and punching a wall that broke his non-pitching hand, the right-hander became the cautionary tale for mega-contracts. His legacy? Teaching teams that just because you can make someone the highest-paid player in baseball doesn’t mean you should.
