Buster Posey, eight months into his tenure as Giants president of baseball operations, has hired former backup catcher Curt Casali and utility infielder Wilmer Flores to baseball operations roles, according to two people with knowledge of the appointments. Casali, who caught 52 games for San Francisco across two seasons, will work in player development with a focus on catching infrastructure. Flores, who logged 490 games in orange and black from 2018 through 2023, joins as a special assistant reporting directly to Posey.

The moves mark the first structural additions Posey has made since replacing Farhan Zaidi in late September. Casali, 35, retired after the 2023 season and had been working informally with catching prospects in the organization's Arizona complex. Flores, 33, remains unsigned after rejecting the Giants' qualifying offer last November—a $21.05 million one-year deal that priced him out of a market that never materialized. His addition to the front office converts dead contract space into institutional memory. Both played under Posey during his final seasons as the everyday catcher, and both backed him up when he transitioned to part-time duty in 2021.

The hires signal a succession strategy built on personal trust rather than external pedigree. Posey spent zero time in front-office apprenticeship before ownership installed him atop baseball operations, a move that rattled agents and rival executives who expected a traditional GM search. Installing former teammates—particularly ones who understand both his communication style and the organization's recent talent struggles—insulates Posey from the usual learning curve. It also creates a vertical loyalty structure: Casali and Flores owe their post-playing careers to Posey, not to ownership or the previous regime. That matters when ownership wants decisiveness. The Giants finished 80-82 in 2024, missing the playoffs for the third straight season despite spending aggressively in free agency.

The timing is worth noting. Flores's hiring comes as San Francisco's $113 million commitment to Matt Chapman and $151 million to Jung Hoo Lee have produced middling results, and as the Padres—90 miles south—near a $4 billion sale to a group led by Dodgers co-owner Peter Guber and billionaire Mark Attanasio, per multiple reports today. The Padres deal would reset West Coast valuations and put pressure on Giants ownership to demonstrate a credible path back to October. Posey's response appears to be consolidation rather than expansion: fewer decision-makers, tighter circles, faster approvals. Casali's catching expertise addresses a system-wide development gap—San Francisco has not produced a homegrown All-Star catcher since Posey himself debuted in 2010. Flores brings something harder to hire: he played in 27 postseason games for the Mets and Giants, understands October roster construction, and was in uniform for the franchise's most recent playoff series in 2021.

The broader pattern emerging is a front office built from the clubhouse up. Posey has retained director of baseball operations Yeshayah Goldfarb and assistant GM Jeremy Shelley from the Zaidi era, but he has not added a traditional GM deputy or poached a rival executive. Instead, he is hiring people who played the game recently and who understand the gap between spreadsheet decisions and dugout execution. The risk is insulation; the upside is speed. Agents expect Posey to lean heavily on Casali and Flores during arbitration prep and extension talks, where personal relationships can accelerate negotiations that typically drag into February.

Posey is due to speak publicly at the MLB GM Meetings in November. Casali and Flores are expected to attend as part of the Giants contingent. San Francisco's next competitive window hinges on whether top prospect Kyle Harrison, who posted a 4.56 ERA across 24 starts in 2024, develops into a rotation anchor, and whether the front office can monetize its $30 million in expiring contracts—Flores, Michael Conforto, and Mike Yastrzemski—into deadline assets if the team stumbles early. The Casali hire suggests Posey is betting on internal development. The Flores hire suggests he is betting on loyalty over resume.

The Giants open 2025 spring training in 119 days. By then, Posey will need to have hired a bench coach to replace Kai Correa, who left for the Guardians, and finalized the club's international spending strategy after MLB raised the bonus pool cap by 12 percent. Casali will oversee that spring's catching program. Flores will sit in on advance scouting meetings and likely shadow Posey during owner check-ins. Both will earn mid-six-figure salaries, per front-office norms. Neither has an official title yet, which is typical for first-year hires still defining their scope.

What matters: Posey is building a front office that looks like a coaching tree. The moves do not generate headlines, but they generate control.
