Zito was once considered one of the best pitchers in the majors while with the Oakland A’s, but has a record of 40-57 since joining the Giants in 2007.
The 2002 Cy Young winner finished this season with a 9-14 record and a 4.15ERA. 2010 marked his fourth consecutive season in which he failed to finish with a record above .500.
San Francisco opted to go with Tim Lincecum, Matt Cain and Jonathan Sanchez as starters in the NLDS against the Atlanta Braves.
Zito made $18.5M this year and is the Giants’ highest paid player.
