Los Angeles Angels manager Ron Washington will miss the rest of the season because of an unspecified medical issue. Washington, the oldest manager in the major leagues at 73, has been sidelined for the past week. He experienced shortness of breath and appeared fatigued toward the end of a four-game series at the New York Yankees that ended on June 19. He flew back to Southern California, underwent a series of tests and was placed on medical leave. Bench coach Ray Montgomery, who had been filling in for Washington, was named interim manager, and infield coach Ryan Goins was promoted to bench coach.
