SEATTLE (AP) The Seattle Mariners and Tampa Bay Rays have completed the first significant trade of the offseason, a six-player swap that sends infielder Brad Miller, first baseman Logan Morrison and pitcher Danny Farquhar to Tampa Bay for pitchers Nathan Karns and C.J. Riefenhauser, and minor league outfielder Boog Powell.
The teams announced the deal Thursday night.
Miller, Morrison and Farquhar played extensive roles for the Mariners last season, but will not be part of the club's future under new general manager Jerry Dipoto and manager Scott Servais. Morrison played in a career-high 146 games last season, hitting .225 with 17 homers. Miller was moved between the middle infield and outfield, playing in 144 games.

Karns likely jumps into Seattle's rotation after starting 26 games last season for the Rays, going 7-5 with a 3.67 ERA. He led American League rookies in innings pitched and strikeouts.
