Buster Posey knows what it takes to be a champion.

Now, his former team, the San Francisco Giants, is hoping that he can recapture some of that glory as the club’s new president of baseball operations.

Posey, 37, was a three-time World Series winner and seven-time All-Star when he played with the Giants from 2009 to 2019 and again in 2021. Posey has also been a member of the Giants ownership group since 2022.

Posey replaces Farhan Zaidi, who was dismissed after six seasons, one winning season, and a sole playoff appearance in 2021.

“We have made the decision to part ways with Farhan Zaidi,” Giants Chairman Greg Johnson said in a statement on Monday. “We appreciate Farhan’s commitment to the organization and his passion for making an impact in our community during his six years with the Giants. Ultimately, the results have not been what we had hoped, and while that responsibility is shared by all of us, we have decided that a change is necessary.

“While these decisions are not easy, we believe it is time for new leadership to elevate our team so we can consistently contend for championships.”

San Francisco has posted three straight losing seasons since setting a franchise record with 107 wins in 2021. That was also the most wins in Major League Baseball (MLB), but the season ended in disappointment as the Giants lost to the Los Angeles Dodgers in the National League Division Series three games to two.

The Giants finished last season at 80–82 and in fourth place in the National League West, nine games behind the division winner Dodgers. The team had a solid roster that included All-Star outfielder Heliot Ramos and starting pitcher Logan Webb, but they could not take the next step toward a postseason berth.

Those disappointing finishes led to the dismissal of Zaidi, who came to the club after serving four years as the general manager of the Dodgers. Under Zaidi’s leadership, Los Angeles won four straight NL West titles, but he struggled to find the same success in San Francisco.

Posey, who the Giants drafted with the fifth overall pick in the 2008 MLB Draft, was a perennial winner and the face of the club as a player. He was named the 2010 National League Rookie of the Year and won the Most Valuable Player award in 2012.

The Giants are hopeful that success can translate to success in the front office. San Francisco has a solid nucleus of players, including Webb and third baseman Matt Chapman, so Posey will not be tasked with completely overhauling the club in his first year as the team’s president.

The Giants announced the team will retain Bob Melvin as the manager.

“We are confident that [Posey] and Bob Melvin will work together to bring back winning baseball to San Francisco,” Johnson said.
