The Royals have traded minor league starter Sean Sedlacek to the Mets for left-handed reliever Jamie Cerda, who split time between Class AAA Norfolk and the Mets. He was 1-1 with a 5.85 ERA with the big club and 3-0 with a 1.67 ERA in the minors. Cerda is expected to be a left-handed insurance policy in the bullpen in case Jeremy Affeldt overcomes his blister problem and earns a spot on the starting rotation.
