Chris Young tossed shutout ball in his Seattle debut Saturday, providing a much-needed pitching boost for the Mariners as they closed spring training with a 2-1 loss to the Colorado Rockies.

With pitchers Hisashi Iwakuma, Taijuan Walker and Stephen Pryor all sidelined, the Mariners signed Young on Thursday after he was released by Washington. The 34-year-old right-hander allowed four hits, struck out two and issued no walks in 4 2-3 innings as he moves into a rotation spot.

Kyle Seager's RBI single in the second was the lone run off Rockies starter Franklin Morales. He worked around five walks and three hits in 5 1-3 innings, a day after he was selected as the fifth starter.

Seattle newcomer Robinson Cano struck out and flied out before exiting in the third, finishing with a .412 spring average.
