The Royals have re-signed right-hander Clayton Mortensen to a minor league deal, according to the MLB.com transactions page. Kansas City acquired Mortensen from the Red Sox in late August in exchange for outfielder Quintin Berry.
The 28-year-old pitched to a 5.34 ERA with 6.2 K/9 and 4.7 BB/9 last season with the Red Sox. For his big league career, Mortensen owns a 4.68 ERA with 6.0 K/9 and 4.0 BB/9 over five seasons spent with the Cardinals, A's, Rockies, and BoSox.
Mortensen is represented by the Beverly Hills Sports Council, according to the MLBTR Agency Database.
