The MLB Trade Deadline is when teams try to make deals to improve their chances of winning, but some teams decided to sell off their best players to get young players instead.
The Marlins added 14 new prospects to their team, which is the most of any team, including Robby Snelling, who is a top prospect in baseball.
The Red Sox traded away 10 players in total, including four players to the Angels for pitcher Luis García.
The Rays, Blue Jays, Angels, and Nationals also made significant moves to improve their farm systems by acquiring promising young players.
