The Oakland A’s acquired first baseman Brandon Moss and lefthanded reliever Ryan Buchter from the Kansas City Royals for righthanded pitcher Jesse Hahn and minor league pitcher Heath Fillmyer. Moss, 34, is in the second year of a 2 year, $12 million deal he signed prior to the 2017 season with the Royals, while Buchter, who turns 31 next month, put up a 2.89 ERA in 2017 while splitting the season between the Padres and the Royals.
Hahn, 28, is the primary piece coming back to Kansas City in this deal.
