Buster Posey, 94 days into his presidency of the San Francisco Giants, hired former batterymates Nick Casali and Luis López to undefined front-office positions, the club announced Thursday. No titles were disclosed. Both played with Posey during his late-career tenure and possess organizational memory of the 2010-2014 championship infrastructure. The moves follow Posey's October dismissal of Farhan Zaidi and signal a shift from spreadsheet authority to field-tested judgment.
Casali, 35, caught for six clubs over nine seasons, including 39 games with San Francisco in 2023. He logged 1,294 career plate appearances and posted a .219 average. López, a 33-year-old Venezuelan infielder, appeared in 12 games for the Giants in 2022 after five seasons in Atlanta's system. Neither possesses traditional front-office credentials—no MBA, no analytics firm pedigree. Both possess Posey's phone number and understand how a contending clubhouse operates when ownership writes checks.
The hires matter because Posey is assembling a parallel decision tree inside 24 Willie Mays Plaza. General manager Pete Putila, a Zaidi lieutenant, remains nominally in charge of baseball operations. But Casali and López answer to Posey, not Putila, and their proximity to the president creates a shadow chain of command. When Posey needs ground truth on a coaching candidate's rapport with catchers, or whether a $200 million free agent's conditioning holds into his age-35 season, he calls men who caught bullpen sessions in humid July, not analysts who modeled workload curves. This is not a repudiation of data—Posey greenlit the Giants' pitch-design investments—but a recognition that veteran players distrust front offices staffed entirely by people who never rode a bus through Scranton.
The timing aligns with San Francisco's aggressive winter. The Giants signed shortstop Willy Adames to a $182 million deal and remain linked to free-agent outfielder Anthony Santander. Payroll is already approaching $200 million, a franchise record. Posey is spending like an owner who sees a 2026 free-agent class headlined by Vladimir Guerrero Jr., Juan Soto, and Corbin Burnes and wants infrastructure in place to pitch them. Casali and López are not the pitch—they are the advance team, the men who ensure that when Posey and majority owner Greg Johnson fly to Miami or Toronto to court a superstar, they speak fluently about how San Francisco develops catchers, manages workload, and treats Spanish-speaking families. López, who played seven seasons in Venezuela's winter league, will handle Latin American pipeline credibility. Casali will translate Oracle Park's pitcher-friendly dimensions into playing-time reality for position players wary of suppressed home-run totals.
The broader pattern resembles Derek Jeter's early moves in Miami, when the Marlins' CEO hired former teammates Gary Denbo and Dan Jennings. That experiment failed because Jeter had no capital and ownership mandated a teardown. Posey has capital—$182 million committed to Adames proves it—and a mandate to win before Oracle Park's attendance erosion becomes structural. The Giants drew 2.74 million fans in 2024, down 11% from 2023 and the lowest since the ballpark opened in 2000. Season-ticket renewals for 2025 are tracking below internal projections. Posey knows this. He spent 12 seasons watching the stands thin during rebuilds.
Watch how Casali and López interact with Putila's analytics staff during spring training. If they attend every advance-scouting meeting and sit in on trade calls, Posey is building a hybrid model. If they focus solely on player-development logistics and cultural integration, they are high-end fixers, not decision-makers. Either way, their presence signals that Posey believes the Giants lost free agents not because they offered insufficient money, but because players doubted the organization's seriousness. Aaron Judge signed with the Yankees for $360 million in December 2022 after San Francisco offered a competitive bid. Shohei Ohtani never returned the Giants' calls in 2023. Casali and López are the answer to a simpler question: When a $300 million free agent calls a friend who played in San Francisco to ask what Posey's really like, does the friend pick up?
The next inflection point arrives in mid-February, when Posey will finalize his 2025 coaching staff. If Casali and López influence those hires—particularly the bullpen coach and catching coordinator—they have real authority. If they do not, they are expensive consultants with nostalgic job titles. Posey's credibility as an operator, distinct from his credibility as a Hall of Fame catcher, depends on whether these hires produce wins or just headlines.
The takeaway
Posey's hiring of Casali and López signals teammate credibility over analytics pedigree as Giants chase **$300 million** free agents in **2026**.

Your next customer won't visit your website. Their AI will.
AI assistants have quietly taken over the first step of buying — they answer from catalogs they can read and shortlist whoever can actually ship. Two questions now decide whether you exist to that buyer: can a machine read your catalog, and can you fulfill the order. Most brands fail one or both and never find out why the orders went elsewhere. The winners of this shift aren't the loudest. They're the most readable. Build for the machine that's about to do the shopping.
