Buster Posey appointed catcher Curt Casali and infielder Javier López to senior advisor roles in the Giants' baseball operations department, extending the franchise's preference for promoting alumni into decision-making positions. Both men played alongside Posey during his active career. Casali caught 114 games across three seasons in San Francisco from 2021 through 2023. López appeared in 205 games for the Giants across two stints, most recently as a September call-up in 2019.

The moves formalize relationships Posey already maintained. He hired former Giants catcher Nick Hundley as a special assistant in December, three months after taking the president job. Casali worked as a catching coordinator in the organization's minor-league system last season before this promotion. López spent 2024 as a roving infield instructor. Both now report directly to Posey and general manager Zack Minasian, attending major-league meetings and participating in personnel decisions.

The institutional logic is straightforward. Posey operates best with people who speak his language—low-ego veterans who played the game recently enough to understand modern pitching arsenals and swing-plane optimization but spent enough time in his orbit to anticipate his priorities without requiring explicit direction. Casali caught 41 percent of would-be basestealers during his Giants tenure, above the league average of 26 percent in those seasons. López posted a 98 OPS+ across parts of 15 major-league seasons, the profile of a player who survived on preparation rather than tools.

The hires also reflect San Francisco's ongoing adjustment to Posey's management style. He prefers small rooms and direct reports over layered bureaucracy. The Giants employed 19 full-time baseball operations staffers when Farhan Zaidi ran the department; that number has dropped to 16 under Posey, with responsibilities consolidated among fewer people who worked alongside him as players. This is not sentiment. It is Posey building an information network he trusts during a roster transition that includes $71 million coming off the books after 2025 and decisions looming on arbitration-eligible relievers.

Casali's role skews technical. He will work with catching prospects at the upper levels and consult on pitch-framing metrics and game-calling analytics. López focuses on infield instruction and Latin American scouting, where his Venezuelan background and fluency in Spanish provide leverage the Giants lacked in previous front-office configurations. Both assignments carry modest salaries—senior advisor deals in baseball operations typically range from $175,000 to $325,000 annually depending on experience and scope—but offer pathways to coordinator or assistant general manager roles if they perform.

The broader pattern matters for sponsors and allocators. Oracle, which holds the stadium naming rights through 2038 at roughly $3 million per year, has expressed interest in front-office stability after three consecutive seasons without a playoff appearance. Ownership views Posey's network as a differentiator in free-agent recruiting, particularly among veteran players who remember his leadership during three World Series runs. Whether that translates to wins depends on execution, but the infrastructure is being assembled.

Watch for additional hires in amateur scouting and international operations before Spring Training. The Giants' 40-man roster includes seven players signed out of Latin America, below the league average of eleven. López's Caracas connections could help close that gap. Casali's promotion also signals likely roster churn behind the plate. Patrick Bailey posted a 77 OPS+ last season; if the Giants pursue a veteran backstop in free agency or trade, Casali will be in the room evaluating mechanics and game-management upside.

The Giants open camp in Scottsdale on February 12. By then, Posey's front office will either include more former teammates or reveal which external hires earned his trust. Either outcome clarifies how San Francisco intends to compete in a division where the Dodgers and Padres outspent them by a combined $247 million in payroll last season.
