San Francisco Giants president Buster Posey has hired former teammates Santiago Casali and Ramón López to baseball operations positions, the team announced Monday. Casali joins as a special assistant, López as a minor-league catching coordinator. Both played with Posey during his final seasons as the Giants' everyday catcher, and both know the system from inside the clubhouse.

Casali, 33, appeared in 201 games across four organizations before retiring last season. López, 30, caught parts of three years in the majors and spent 2023 in Triple-A Sacramento. Neither is expected to carry decision-making weight on major-league roster construction—the Giants already employ a president of baseball operations in Pete Putila—but the hires signal Posey's early emphasis on player development infrastructure. Casali will work across all levels of the organization; López reports to catching coordinator Bill Hayes and will focus on pitch framing, game-calling mechanics, and the club's internal biomechanics program.

The moves matter because Posey is staffing from a shallow bench. He took over in late September with no prior front-office experience, and while the Giants retained Putila and general manager Zack Minasian, Posey needed trusted voices who understand the clubhouse culture he built during three World Series runs. Hiring former teammates is the oldest play in the executive handbook, but it works when the new president needs fluent translators between the analytics department and the dugout. Casali spent time with Cincinnati's player-development staff before retiring and has relationships with independent-ball coaching networks the Giants use for low-minors instruction. López played winter ball in Mexico and Venezuela, which keeps him connected to Latin American scouting pipelines the team has underinvested in since 2019.

The appointments also clarify Posey's bandwidth problem. The Giants need rotation help—they ranked 23rd in starting-pitcher ERA last season and have roughly $80M in payroll space before hitting the competitive-balance tax threshold—but Posey has spent October and November in hiring meetings rather than agent calls. Corbin Burnes, Blake Snell, and Max Fried remain unsigned. The Giants have been in conversations on all three, according to two people familiar with the discussions, but Posey delegated most of those talks to Putila and Minasian while he worked on internal structure. That is the correct sequencing for a first-time president, but it also means the Giants are not moving faster than the Dodgers, Mets, or Yankees in the premium-arms market. Casali and López bring institutional continuity, but they do not sign pitchers.

Posey's hiring strategy tracks with broader MLB trends. Over the past 18 months, at least nine teams have added recently retired players to front-office roles, most in player-development or advance-scouting capacities. The Yankees hired Tino Martinez as a spring-training instructor. The Phillies brought back Ryan Howard for minor-league coaching. The logic is straightforward: veteran players can speak to current roster construction in language that resonates with active players, and they cost less than poaching executives from other organizations. Casali's deal is believed to be in the low six figures annually; López's is lower. For comparison, the Mets paid roughly $2M per year to hire David Stearns from Milwaukee.

Watch whether Posey adds another former teammate to the major-league coaching staff. Matt Cain, who retired in 2017, has been working as a special assistant and is considered a candidate for pitching coach if the Giants move on from Bryan Price. Hunter Pence, who retired in 2020, has expressed interest in a player-development role but is under contract with NBC Sports Bay Area through next season. The Giants also need a new hitting coach—Justin Viele left for Texas in November—and that hire will signal whether Posey prioritizes relationships or résumés. The team's offensive rankings have been middle-of-the-pack for three years, and sponsors who bought premium seating based on 2021 playoff runs are asking questions.

Posey now has the front-office depth to delegate minor-league oversight and focus on the rotation market. Burnes is expected to command $200M over seven years. Snell, coming off a Cy Young season in San Diego, wants at least $180M. Fried is the fallback at $140M. The Giants have the payroll capacity but not the organizational momentum—they have not signed a premium free agent to a deal longer than four years since 2016. Casali and López do not change that pattern, but they free Posey to try.
