Answer
The Chicago Cubs traded for Nick Castellanos in 2019, giving up minor league outfielder Nelson Velazquez and pitcher Matt Swarmer. Castellanos had been playing for the Detroit Tigers since 2015, and he had a breakout season in 2019, hitting.309 with 27 home runs and 95 RBIs. The Cubs were looking to add some power to their lineup, and Castellanos was seen as a perfect fit.
