After 12 seasons in the MLB, former Chicago Cubs ace Jake Arrieta has officially announced his retirement.

Arrieta, 36, only spent five seasons with the Cubs after arriving in 2013, but was spectacular at his peak.

He won the 2015 NL Cy Young award – finishing sixth in MVP voting that season – leading to a 2016 season where he earned his only All-Star appearance and led the Cubs to their first World Series in 108 years, breaking the league's longest drought.

In the World Series against Cleveland, Arrieta was at the top of his game, going 2-0 in his two starts with an ERA of 2.38 to cement his legacy with the club.

He started his career with the Baltimore Orioles, and signed a three-year, $75million deal with the Philadelphia Phillies after his Cubs success, before finishing up his career with the San Diego Padres.
