SAN FRANCISCO (AP) - A person with direct knowledge of the decision says San Francisco Giants catcher Buster Posey plans to announce his retirement Thursday.

The Giants said last month that they would exercise Posey's $22 million club option for the 2022 season as long as the veteran catcher wanted to keep playing after a stellar year.

Posey helped lead the Giants to a franchise-record 107 wins and their first NL West title since 2012.
