Tino Martinez was an excellent college baseball player at the University of Tampa and a Gold Medalist at the Seoul Olympics.  Martinez was a first round pick (14^th Overall) in 1988, and he would debut with Seattle in 1990. 

Ken Phelps never really got the chance to be an everyday player in his career, mostly used in platooning situations, but that makes his days in baseball sound so basic. 

Dave Valle made his Major League debut in 1984 with the Seattle Mariners, and he would play for the M's infrequently over the next three seasons before he would play the lion's share at Catcher in 1987.    

From Canada, James Paxton was a fourth round pick who would play collegiately at the University of Kentucky.  Paxton debuted in 2013 and had four starts, winning three of them.  Over the next three seasons, Paxton was often on the disabled list, and he had a pedestrian 15-15 record, but by 2017, he was healthy and was able to show what he could do.
