Johnson is the same player that tied game 162 between the Yankees and Rays in 2011with a two-run homerun that pushed the game into extra innings. The Rays would go on to clinch he American League wild card with the win, as well as eliminate the Boston Red Sox.
In 2012, Johnson was a member of the White Sox Triple-A affiliate before being called-up to the Majors for 14 games in September. He went 8-for-22 at the plate.
As our own Matt Filippi pointed out on Twitter, his career slash line is .237/.338/.412 (102 wRC+.) Another one of Johnson's strengths is the ability to garner walks (9 in 14 games last year.)
