12. Jose Ramirez
Jose Ramirez had already broken out as a star prior to 2018, but his season can still be considered a breakout campaign due to the incredible year that Ramirez had.
Ramirez joined the elusive 30-30 club this year, as he hit 39 home runs and stole 34 bases. Ramirez won his second Silver Slugger and eclipsed 100 RBI for the first time.
