A's celebrate longtime employees
The A's honored a pair of employees who recently celebrated their 50th anniversary at the Coliseum before Sunday's game: Harold Miller and Max Jacinto, who were working as ticket takers on Sept. 18, 1966, when the Coliseum opened its doors. They were presented personalized jerseys and team-signed bats before throwing out the ceremonial first pitches.
