Massive Tax Hit: MLB Star’s Bold Move

Merrill Kelly rejected a lucrative three-year offer from the San Diego Padres to sign a shorter, comparable deal with the Arizona Diamondbacks, solely because California’s 13.3% state income tax would devour millions from his pocket.

Kelly’s Career Path to Free Agency

Merrill Kelly spent his first seven years with the Arizona Diamondbacks. In July 2025, the Texas Rangers acquired him, where he pitched 10 games. Kelly finished 2025 with a 12-9 record split between Arizona and Texas. The 2025 offseason brought free agency. He received a three-year offer from the Padres valued comparably to $40 million. Kelly, a numbers-focused pitcher from Arizona high school and Arizona State University, calculated tax impacts with his agent.

California imposes a 13.3% top marginal rate on income over $1 million. Arizona levies a flat 2.5%. This 10.8% gap on $10-20 million annual value deals means millions less take-home pay in San Diego. Kelly prioritized net earnings and personal Arizona roots over coastal appeal. His transparency sets this apart from typical secretive negotiations.

Tax Calculations That Sealed the Deal

Kelly’s agent, dubbed his “numbers guy,” ran precise financials. The Padres’ three-year offer matched the value of Arizona’s two-year, $40 million contract with a 2028 vesting option. California taxes stripped too much upfront. Kelly stated on the “Foul Territory” podcast: “They take too much money out of my pocket… it just made more sense to come home.” He joked about preferring desert over ocean despite fondness for San Diego.

The Padres declined comment on negotiations. Arizona offered familiarity after seven years plus tax savings. Kelly signed recently, prepping for the Diamondbacks’ 2026 opener. This quantitative choice over sentiment underscores player agency in MLB free agency, where unions protect mobility.

Precedents of Tax-Driven Athlete Migration

Pitcher Trevor Bauer avoided high-tax states in 2021. California teams often lose bids to Florida and Texas, both with 0% state income tax. Forums predict ongoing talent drain from California MLB clubs. Kelly’s case aligns with economic patterns: athletes weigh net pay heavily without full no-trade clauses. Arizona’s lack of sales tax on some items and desert lifestyle added personal pull.

High-tax environments repel high earners. Kelly’s decision validates common sense: individuals chase maximum after-tax income. This aligns with conservative values favoring low taxes to retain talent and economic vitality. California loses revenue from unearned athlete income while fans face weaker rotations.

Impacts on Teams, States, and MLB Future

Short-term, Diamondbacks gain rotation stability cheaply. Padres pivot to other pitchers amid gaps. Long-term, low-tax markets like Arizona, Texas, and Florida attract stars, pressuring California competitiveness. Forums warn of declining fan draw and performance. Politically, stories like Kelly’s fuel calls for tax reform to halt talent exodus.

Sports media labels this textbook tax arbitrage. Kelly balances San Diego affection with finances, yet math prevailed. Broader MLB shifts favor tax havens, potentially forcing shorter deals or incentives from high-tax teams. Players’ candor like Kelly’s highlights quantitative reality over nostalgia.
