Excitement is building among baseball fanbases as the trade deadline draws closer, with many of them hoping their team pulls off a blockbuster deal.
Teams typically set out to make a trade that will address a specific need or want, and it may take a while to determine whether that team did so successfully. A trade can have a sizable effect on a team's fortunes, both good and bad. But occasionally, a team can pull off a deal that overwhelmingly surpasses all expectations. These trade steals are rare, and they're even more unlikely at the MLB trade deadline.
