For the second and final time, Aaron Hill makes an appearance on this list. Coming off a fantastic 2009 regular season, Hill was destined for big things in 2010. It started off well, as over the course of March 2010, Aaron Hill was absolutely unconscious at the plate.
In 48 at-bats, Hill beat the cover off the baseball, slashing an absolutely ridiculous line of .417/.517/.854. to go along with his six homeruns and 15 RBIs. Hill’s 2010 spring training performance was perhaps the best in the past ten years.
Unfortunately for the team, Blue Jays fans, and Hill himself, his hot bat in spring training quickly cooled off come the regular season.
While he still was able to hit 26 homeruns, but it was the rest of his production that really fell off. Hill was only able to drive in 68 RBIs, and his average hovered around the Mendoza line all season, finishing with a putrid slash line of .205/.271/.394.
In 2011 Hill continued to struggle, and was subsequently traded to the Arizona Diamondbacks, where he went on to have a few good seasons before seeing his production fall off again.
