The Twins acquired starting pitcher Chase De Jong, a 24-year-old, who has started 21 games for the Mariners' AA affiliate. He's 5-5 with a 3.80 ERA. In 120 2/3 innings, he has walked 34 and struck out 89. He has already pitched in the Blue Jays (2012-15), Dodgers (2015-16) systems, as well as the Mariners the last three seasons. He was originally the Blue Jays second-round pick in 2012.
Infielder Ryan Costello is the other player acquired for Duke. The 22-year-old has hit .266 with 24 doubles, two triples and 16 home runs for Class A Clinton in the Midwest League where he was managed by Denny Hocking. He was the Mariners 31st round pick last June out of Central Connecticut University in New Britain, Connecticut.
Zack Duke will head to the Mariners after a solid season with the Twins.
The Twins will pay a small part of the remainder of Duke's 2018 contract.
This evening, Duke posted the following to Twitter, thanking Twins fans and looking forward to Seattle.
Soon after, Ryan Costello thanked the Mariners and says he's looking forward to joining the Twins.
