PEORIA, Ariz. -- Cuban rookie Roenis Elias has earned a spot in the Seattle Mariners' rotation.
The 25-year-old left-hander has never pitched above Double-A after a fine spring in which he had a 2.04 ERA in five games -- two starts. He walked eight and struck out eight.
Elias and Beimel were added to the 40-man roster.
Elias and recently signed right-hander Chris Young will take the spots of injured starters Hisashi Iwakuma and Taijuan Walker, who are expected to begin the season on the disabled list. Seattle opens Monday in Anaheim, Calif., against the Angels.
Also, the Mariners optioned infielder Nick Franklin to Tacoma, clearing the way for Brad Miller to open the regular season as the team's starting shortstop after a strong spring training in which he batted .439 in 19 games.
The Mariners re-assigned pitchers Zach Miner, Dominic Leone, Ramon Ramirez and Carson Smith to minor league camp. Catcher Humberto Quintero and outfielder Endy Chavez joined them, and outfielder Xavier Avery and infielder Carlos Triunfel were designated for assignment.
