The Mariners take on the Rockies and their ace Chase Dollander today. Luis Castillo will take the ball for the Mariners.

Also scheduled to pitch for the Mariners: Casey Lawrence, José Ferrer, Matt Brash, Carlos Vargas, Yosver Zulueta

Bryce Miller will throw a 25-pitch bullpen today as he continues to work his way back from oblique soreness. The Mariners won’t say whether or not he’ll be ready to start the season but it doesn’t feel likely at this point; Cooper Criswell seems like a lock to make the roster at this point, and maybe both him and Emerson Hancock.

Yesterday the Mariners re-assigned RHP Nick Davila to minor league camp; today they made several more cuts, optioning Blas Castaño and Domingo Gonzalez to Triple-A Tacoma and re-assigning OF Lazaro Montes, RHP Tyler Cleveland, RHP Michael Morales, OF Spencer Packard and C Nick Raposo to minor-league camp.
