Barry Zito has decided to retire after 14 Major League seasons.

Zito announced his retirement Monday in a post on The Players' Tribune.

"My baseball career has been a mirror to my life off the field, full of euphoric highs and devastating lows," Zito wrote. "I've been at the top of a rotation and the 25th man on a roster. I've started Game 1 of a World Series in one year, and I've been left off of a postseason roster in another. I've been labeled as both drastically underpaid and severely overpaid. I've been praised as a savior and deemed a curse."

He leaves baseball with a record of 165-143 and a 4.04 ERA.

"Beyond all of the achievements, the single thing that fulfills me today is the acceptance of myself as a worthy and valuable person, regardless of what my stature or position in the world was on a given day of my career," Zito wrote.
