• NBA Hall of Famer Bill Russell is scheduled to throw out the ceremonial first pitch before Sunday's 1:10 p.m. PT game against the Orioles as part of a Mariners celebration of the contributions of African Americans in the Seattle community.
The pregame African American Heritage Day ceremony will also include former Sonics star Fred Brown, Seattle Fire Chief Gregory Dean, real estate developer Theresa Frank, architect Donald King, former Mount Zion Baptist Church pastor Rev. Samuel McKinney, and Herb Simpson, the last known surviving member of the Seattle Steelheads Negro Leagues team.
• McClendon said Iwakuma will pitch Tuesday's game in Cleveland as the Mariners open a six-game road trip following an off-day on Monday. That means the club will skip Walker's next turn and keep Iwakuma and the other starters on a normal four days' rest.
