San Francisco Giants president of baseball operations Buster Posey has hired former teammates Nick Casali and Felipe López to the front office, the first significant structural additions since Posey replaced Farhan Zaidi in late September. Casali joins as a player development advisor. López takes a scouting role focused on Latin American markets.
Posey played with Casali during the catcher's 2021-2022 stint in San Francisco. López overlapped with Posey briefly in 2010 before returning as a coach in 2023. Both hires carry the president's personal endorsement, a pattern emerging in Posey's early personnel moves. The Giants have not disclosed compensation structures, but comparable development roles at West Coast organizations currently pay $150,000-$250,000 base plus performance incentives tied to player advancement rates.
The moves signal Posey is building a parallel development track inside an organization that prioritized analytics infrastructure under Zaidi. The previous regime added 14 analysts between 2019 and 2023. Player development staffing grew modestly, adding three coordinators over the same period. Zaidi's Giants ranked 23rd in Baseball America's farm system rankings at his departure. Posey is staffing the gap between models and fields.
Casali's hire matters for catching development specifically. The Giants have four catchers on the 40-man roster, none with more than 180 big-league games. Casali caught 89 games across two seasons in San Francisco, enough to know Oracle Park's dimensions and the organization's pitch-framing preferences. He also played under three managers in five organizations, the kind of institutional knowledge useful when teaching backup catchers how to survive. Development advisors at this level typically work 60-80 days annually, splitting time between minor-league sites and the big-league spring facility.
López's scouting remit is the more immediate business problem. The Giants' international signing budget for 2025 is $6.26 million, 11th in MLB. They signed seven players for $100,000-plus bonuses in the last signing period, trailing the Padres' 12 and Dodgers' 15. López spent 12 years as a player across the majors and played winter ball in the Dominican Republic through 2014. He knows which academies produce which skill sets and which agents move players where. The Giants need to convert that network into bodies before July's international signing window.
The broader pattern is Posey centralizing baseball operations around people who have been in uniform recently. The front office now includes three former Giants players hired since September: Casali, López, and assistant GM Zack Minasian, who played briefly in the minors. Zaidi's staff leaned heavily on Ivy League analytics graduates. Posey is adding playing experience without dismantling the quantitative layer. The Giants' director of quantitative analysis, hired in 2021, remains in place. So does the director of baseball systems, added in 2022.
The timing also matters for Bob Melvin's coaching staff. The Giants have not yet hired a bench coach after Kai Correa left for the Rays in November. Casali's development role and López's scouting assignment keep both outside the dugout, but they add institutional continuity while Posey evaluates internal candidates. The bench coach search has been quiet for six weeks, longer than the typical 3-4 week window for this level of hire. That suggests Posey is either waiting on someone under contract elsewhere or considering an unconventional internal promotion.
Watch for the Giants' 40-man roster moves before the February 15 arbitration filing deadline. Teams typically add player development staff in November, then adjust the roster in February based on what the new hires recommend. The Giants have four open spots and a farm system that needs urgent talent injection. López's scouting network will be tested in the July 2025 international window. Casali's development role will show results in how the organization's catchers perform in the first half of the minor-league season, which begins in April.
Posey has now made eight front office or coaching changes in 14 weeks on the job. The president's phone is still ringing.
The takeaway
Posey rebuilding Giants player development with former teammates, favoring field experience over analytics-first model that defined Zaidi era.

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.
