- Former Cy Young winner Barry Zito officially announced his retirement on Monday, ending a 15-year career "full of euphoric highs and devastating lows" that included three All-Star appearances and a World Series title. The 37-year-old, who played for the Oakland Athletics (in two stints) and the San Francisco Giants, signed off from the sport in an article which he posted on the Players' Tribune website. "I'm retiring today from baseball, but I'll never be too far away from the game that made me who I am," said left-hander Zito, who plans to start a new career as a song writer.
