John Mayberry Jr (2011)
Mayberry displayed promising power in brief time with the Phillies in 2009 and 2010. He put it together in 2011, hitting .273 with 17 doubles and 15 home runs in only 267 at-bats. Add in an .854 OPS and it appeared Mayberry was heading for a successful career. However, despite hitting 14 home runs in 2012, Mayberry’s home run total and batting average plummeted over the next few seasons. He last played with the Mets in 2015, hitting .164 and has a career .235 average with 56 home runs.
