Perhaps you've forgotten after a dizzying playoff run and an unexpectedly great season, but the Yankees actually did some rebuilding recently. Their highest profile deals came at the 2016 trade deadline, but their final true rebuilding move came last offseason, when they shipped Brian McCann to the Astros. They received a couple of pitching prospects in return, Jorge Guzman and Albert Abreu.
Abreu, a right-hander coming off his age-21 season, was the prize of the deal. He was well-regarded entering the season, coming in at 82nd on Baseball Prosepectus' Top 101 prospects list.
