Hitting Coach for San Jose Giants (MiLB) & Former MLB Catcher with the Seattle Mariners
Mike Marjama played catcher at Granite Bay High School in Roseville, California, before heading to Long Beach State where he was drafted in the 14th round of the 2011 MLB Draft by the Seattle Mariners. He worked his way through Seattle's minor league system over six seasons, developing into a reliable defensive backstop while refining his offensive approach. Marjama reached the majors with the Mariners in 2017-2018, appearing in 15 games with a .167 batting average, 1 home run, and 1 RBI during his brief MLB tenure. Following his playing career, he brings elite-level catching fundamentals and game management skills from his professional experience, specializing in defensive positioning, pitcher-catcher communication, and the mental aspects of the position that he mastered while advancing from the draft to the major leagues.
