LUIS GONZALEZ, OF, DIAMONDBACKS, 2001
Gonzalez played baseball for 19 seasons and was a five-time All-Star, so it may be a bit of a stretch to call him a “one-hit wonder.” Still, what he did in 2001 so exceeded expectations that it’s impossible to leave him off this list. Gonzalez smacked a career-best 57 home runs, drove in 142 runs and sported an OPS of 1.117. His previous career highs in those three categories were 31, 114 and .952 respectively. Whatever Gonzalez did to have a career year at the age of 33, it worked.
