Kevin McGonigle signed an eight-year, $150 million contract extension with the Detroit Tigers on Wednesday, a deal that keeps the rookie shortstop under team control through 2034 and gives him the most guaranteed money ever awarded to a player with less than 100 days’ service time.
The extension came after McGonigle had played only 17 major league games. It also broke the record that had belonged to Konnor Griffin of the Pirates for just eight days, after Griffin signed a nine-year, $140 million deal. In a market that has moved fast all year, McGonigle’s payday now sits at the top of a growing class of early-career contracts that take players well beyond their first few seasons.
The structure is not new, but it has been spreading. Evan Longoria broke the seal on this kind of extension in 2008, and researchers Jon Becker and Ben Clemens found 29 instances of players receiving deals that carried into free agency before they had played a full season in the majors, not counting players arriving from Asia. Six of those deals were signed in the past year, while 18 started in 2020 or later and 23 have kicked in since 2018.
That rush has changed the way clubs buy certainty and the way young players trade it away. Cooper Pratt of the Brewers and Colt Emerson of the Mariners also signed eight-year extensions, and the list of players who can reach free agency after 2028 already includes Tarik Skubal, Bo Bichette and Kyle Tucker. McGonigle’s deal is the latest sign that the market for unproven talent is moving higher, faster, and with fewer pauses than it did even a few years ago.
