San Francisco Giants president of baseball operations Buster Posey has hired Santiago Casali and Pablo López into front office roles, marking the second wave of internal promotions since his September 2024 appointment. Casali caught Posey during his final seasons; López played infield depth from 2019 through 2021. Neither brings traditional front-office pedigree. Both bring locker-room proximity to a president building operations around shared memory.

Casali joins as special assistant to baseball operations. López takes a scouting and player development hybrid role. The Giants confirmed both hires internally this week but have not disclosed salary bands or reporting structure. Casali, 33, last appeared in affiliated ball in 2023 with Triple-A Sacramento. López, 35, retired after a brief 2022 stint in independent ball. Posey himself retired in 2021 at 34 and entered the front office 27 months later with no intermediary stops in media or advisory roles.

The pattern is roster continuity as organizational strategy. Posey has now hired three former teammates since taking the baseball operations chair: director of player development Pat Burrell came aboard in October, Casali and López this month. All three played under current manager Bob Melvin when he coached in Oakland or during his two seasons piloting San Francisco. The overlap is not incidental. The Giants finished 80-82 in 2024, fourth in the National League West, and missed the playoffs for the third consecutive year. Ownership granted Posey wide latitude to reshape decision-making without requiring immediate wins.

What matters here is signal about how Posey views the general manager job he has declined to fill. Traditional baseball operations hierarchies run GM—assistant GM—coordinators—scouts. Posey has instead staffed laterally: Burrell oversees player development, Casali assists broadly, López splits evaluating and coaching. None hold the GM title. The front office now resembles a peer network more than a pyramid. For sponsors and media partners, this creates unclear escalation paths when conflicts arise over player appearances or brand integrations. For rival front offices, it signals that Posey operates as his own clearinghouse, which accelerates some conversations and stalls others when he is unavailable.

The archetype is not unprecedented. Theo Epstein hired former Cubs closer Kerry Wood into a front-office role in 2014; Wood lasted two seasons before moving to advisory work. The Yankees employed Andy Pettitte briefly in player development. The success rate for recently retired players entering operations without minor-league coaching or scouting apprenticeships is uneven, largely because the skillset gap between reading a clubhouse and reading a 60-game draft board is wider than proximity suggests. Posey is betting that cultural fluency and roster trust offset technical inexperience, particularly in player-facing roles where Casali and López will spend time in spring training and instructional leagues.

What to watch: The Giants' $197 million payroll expires $48 million in commitments after 2025, opening space for extensions or free-agent adds. If Posey's front office handles those negotiations internally without hiring a GM, the Casali and López appointments gain explanatory weight—team-building through relationships rather than data infrastructure. Coordinator hires for hitting and pitching development will surface by late February. Oracle Park's $3.2 million annual naming-rights deal renews in July; sponsor expectations around front-office accessibility will test Posey's decentralized model.

The Giants have not hired a traditional general manager in 147 days. Casali and López are filling the vacuum with loyalty, not leverage.
