PEORIA, AZ—Left-hander Jason Vargas and right-hander Doug Fister will likely be in the Mariners' rotation to begin the season with Cliff Lee injured.
Manager Don Wakamatsu said Friday that assumes Fister's bruised right forearm continues to get better.
Wakamatsu wants to see Fister pitch one more time in a game before the team breaks camp Thursday.
The 26-year-old Fister was hit in the arm by a line drive by Cincinnati's Joey Votto on March 19. He made 11 starts for Seattle last season after a call up in August.
Vargas has been Seattle's most consistent starter this spring behind Felix Hernandez. Ian Snell and Ryan Rowland-Smith appear to be the other starters to begin the season.
Wakamatsu also says he expects Casey Kotchman to be the everyday first baseman because of his defense.
