Few trade deadline acquisitions in recent memory felt more impactful than Nick Castellanos. The Chicago Cubs snuck the deal in just ahead of the trade deadline in July 2019, sending prospects Paul Richan and Alex Lange to the Detroit Tigers in exchange for the slugging outfielder.
Castellanos endeared himself to Cubs fans immediately, going on an otherworldly tear after coming to Chicago, delivering exactly what the team had hoped he would when making the move: impressive slug and the ability to crush left-handed pitching. In just 51 games, Castellanos delivered 1.7 bWAR, slashing .321/.356/.646 in 225 plate appearances.
