Some trades can turn a team around, bringing winning seasons to a baseball team. These are definitely not that kind of trade. Here is a look at some of the worst trades in baseball history.

Boston Red Sox Trade Babe Ruth to the New York Yankees

This is one of the biggest mistakes a major league baseball team ever made. In 1920, the Boston Red Sox traded this powerhouse slugger and lefty pitcher for the sum of $100,000 cash.

There's even a superstition about this horrible trade. Many people believed that the reason the Red Sox didn't win a World Series for 86 year, between 1918 and 2004, was because of the Curse of the Bambino.

Babe Ruth is a giant in MLB history for very good reasons. Among his career stats are 714 home runs, .690 slugging percentage, and 2,213 runs batted in.

Miami Marlins Trade Christian Yelich to the Milwaukee Brewers

This is proof that more is not always better. In 2017, the Marlins got four players for one in this trade, but what they lost was Yelich. This centerfielder has a career total of 500 RBI and 131 home runs, just for a start.

Boston Red Sox Trade Jeff Bagwell to the Houston Astros

This 1990 trade didn't look like a bad deal in the beginning. Jeff Bagwell was traded by the Red Sox for Astros Larry Anderson. While Andersen was a solid player, who helped them win the American League East title, he would leave at the end of that season.

Bagwell, on the other hand, went on to become one of the Astros best players of all time. He won the Rookie of the Year in 1991, the National League MVP in 1994, and hit 449 home runs.

Miami Marlins Trade Derrek Lee to the Chicago Cubs

In 2003, Derrek Lee was a World Series Champion with the Florida Marlins. They traded him to the Cubs that year, in exchange for Hee-Seop Choi, who was a AAA player.

While Choi was a powerful left-handed hitter, he just wasn't up to Lee's quality. In 2005, Lee went on to win the National League batting title. He was an All-Star selection twice and was winner of the Gold Glove Award three times.

Choi, who the Marlins got for Lee, started off hot but his performance cooled rather quickly. After the 2005 season, Choi never wore a uniform for the Marlins, or any other major league baseball team, ever again.

Montreal Expos Trade Randy Johnson to the Miami Mariners

In this 1989 trade mistake, the Expos traded one of the best left-handed pitchers of all time, Randy Johnson, to the Mariners, along with two other players, for Mark Langston and Mike Campbell.

Johnson went on the win five Cy Young awards, make ten All-Star turns, and win more than 300 games in his career with the Mariners.

Oakland As Trade Mark McGwire to the St. Louis Cardinals

In 1997, the As traded this American League Rookie of the Year to the Cardinals. McGwire would go on to make baseball history and find his place in the Baseball Hall of Fame.

Los Angeles Dodgers Trade Pedro Martinez to the Montreal Expos

In 1988, the Dodgers signed Pedro Martinez as a free agent. When he made his debut against the Reds in 1992, his performance in two scoreless innings was anything but noteworthy.

The Dodgers traded him in 1993, just one year later. The traded him to the Expos for Delino DeShields, assuming that Martinez would never have any kind of career as a starter.

But from those humble beginnings came a baseball powerhouse. Martinez is one of the best right-handed pitchers in the history of the game. He has been an All-Star eight times, has won the Cy Young Award three times, along with being a 2004 World Series champion.

Detroit Tigers Trade John Smoltz to the Atlanta Braves

The year was 1987. After two years on the team, John Smoltz was traded to the Braves for Doyle Alexander, a 36-year-old pitcher. Smoltz was just twenty at the time. While Alexander did do some good work with the Braves, his time with them was short.

Smoltz, on the other hand, went on to become the second pitcher in the history of the game to have accomplished both 20 wins and 50 saves in a single season. He also holds the record in major league baseball history to surpass 200 wins and 150 saves. He is an eight-time All-Star and led the National League in strikeouts in 1992, with 215.

Phillies Trade Ryne Sandberg to the Chicago Cubs

In 1982, one of the most lopsided trades in baseball was made. Ryne Sandberg was traded to the Cubs, where he would reach 282 home runs and 1061 RBI.

Toronto Blue Jays Trade Noah Syndergaard to the New York Mets

In 2012, after just two years with the Blue Jays, Syndergaard was traded to the Mets. Syndergaard would go on to become an All-Star.
