Johnson, 26, logged five seasons in the Oakland Athletics organization and the left-handed hitting outfielder reached as high as High-A Stockton in the California League. Drafted twice previously by the Florida Marlins in 2003 and the San Diego Padres in 2004, the Oakland Athletics grabbed Johnson in the 14th Round of the 2006 MLB Entry Draft. Johnson was chosen as the MVP of the 2008 Kane County Cougars, Oakland’s Single-A Midwest League franchise. Playing in 109 games, Johnson hit .281 with 13 homers and 74 RBI. The Jackson, Miss. Native also swiped 11 bases and scored a career best 55 runs in 413 at bats.
Following two years as a starter at Meridian Community College with an appearance in the NJCAA Division II World Series, Johnson moved to SMU, batting .363 in his lone season with the Golden Eagles and earning First Team All Conference USA honors after leading the team in total bases. Johnson was also named to the NCAA Tuscaloosa Regional All-Tournament team. Several current RailCats were teammates with Johnson as Mike Massaro and Derrick Gordon also came from the Athletics system.
