The Mariners continued to make tweaks and minor changes to their roster as spring training lingers just over 30 days away. On Tuesday, general manager Jerry Dipoto made a trade for starting pitching depth, acquiring right-handed pitcher Joe Wieland from the Los Angeles Dodgers in exchange for minor league infielder Erick Mejia. To make room on the 40-man roster for Wieland, right-handed pitcher A.J. Schugel was designated for assignment.
Wieland spent the bulk of his 2015 season with Class AAA Oklahoma, making 21 starts and one relief appearance.
