The Royals acquired Yuniesky Betancourt and cash from the Mariners for a pair of minor league pitchers, according to Joe Hamrahi of Baseball Daily Digest. Betancourt makes at least $10MM before his current deal expires, so it'll be interesting to see how much the Mariners are contributing.
Here's some info on the pitchers, from Ryan Divish of the Tacoma News Tribune. Danny Cortes, 22, will report to AA. He's 6-2 with a 3.12 ERA in his last eleven games after a rough start to the year in the Royals organization. He was the Royals' minor league pitcher of the year last year and Baseball America labelled him the best minor league pitcher in the organization entering this year.
Derrick Saito, 21, has struck out more than a batter per inning in A ball. The 21-year-old lefty will begin his Mariners career in A ball.
