SAN FRANCISCO (AP) – San Francisco Giants catcher Buster Posey plans to announce his retirement Thursday. That’s according to a person spoke to The Associated Press on condition of anonymity because Posey had yet to make his decision public. The 34-year-old Posey just helped the Giants win a team-record 107 games this past season, batting .304 with 18 homers and 56 RBIs. 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. He is three years removed from major hip surgery.
