Pilkington was acquired by Cleveland on Thursday in a trade which sent Cesar Hernandez to the White Sox, Bob Nightengale of USA Today reports.
Pilkington joins an organization that has a good reputation when it comes to developing pitchers. The 2018 third-round pick isn't a top prospect, but he's shown promise this season in 14 Double-A starts, riding a 30.5 percent strikeout rate to a 3.48 ERA.
