Chicago Cubs’ Jake Arrieta was drafted in the fifth round of the 2008 draft by the Baltimore Orioles. Arrieta made a name for himself in the minor leagues with the Orioles, by 2009 he was ranked as the 52nd prospect in the MLB. Arrieta made his Major League debut in 2010.
Soon after being called up, Arrieta struggled, tossing a 5.46 ERA through 2010-2013. This being the reason that Arrieta and Pedro Strop were traded to the Chicago Cubs in return for Scott Feldman and Steve Clevenger. In hindsight, one of the best trades for the Cubs in the history of the franchise.
