The Detroit Tigers saw many other MLB teams sign their star rookies to new mega deals and decided to get in on the act themselves. The Tigers announced an eight-year, $150 million extension with star shortstop — and former top prospect — Kevin McGonigle on Wednesday.
McGonigle, 21, entered the season as the consensus No. 2 prospect in baseball. He made the Tigers out of spring training and is off to a promising start in his first taste of the majors.

The deal covers five seasons of team control and buys out three years of McGonigle’s free agency. McGonigle will see his salary jump in each year of the contract, topping out at $23 million in 2033 and 2034.
Despite his age and inexperience, McGonigle has hit like a veteran in his first MLB season. Through 17 games, the shortstop is slashing .311/.417/.492 with a home run and eight RBI. He has shown incredible plate discipline and has 11 walks against eight strikeouts so far.
While it typically takes even the best prospects some time to adjust to the majors, McGonigle was always supposed to be special. After being selected by the team in the first round of the 2023 MLB Draft, McGonigle shot up prospect boards after a solid minor-league debut and an impressive 2024 season.
Entering last season, McGonigle was rated in the top 30 on nearly all prospect lists, with Baseball Prospectus already considering him the No. 6 overall prospect in the game. He lived up to that billing with a fantastic season, hitting .305/.408/.583 across three minor-league levels.
When Baseball America, Baseball Prospectus and MLB.com released their 2026 top-100 prospect lists, McGonigle ranked No. 2 overall on all three, behind only Pittsburgh Pirates shortstop Konnor Griffin, who was the consensus No. 1 prospect on all three lists.
While Griffin didn’t open the year in the majors, he was quickly called up by the Pirates and signed a mega-extension with the team. Griffin’s deal with the Pirates is for nine years and is said to be worth $140 million.
Griffin and McGonigle are far from the only top prospects with little-to-no MLB experience to ink massive extensions with their organizations this season. In late March, the Seattle Mariners signed shortstop prospect Colt Emerson to a $95 million extension. It was a record number for a player yet to make his major-league debut. Emerson has not been called up to the Mariners just yet, though team president of baseball operations Jerry Dipoto said Emerson was “as close as they come” to making the majors during an appearance on MLB Network on Monday.
While MLB teams have always been willing to sign young players to long-term contracts, the cost of doing so has gotten higher this year. That likely speaks to the individual talent of each player who signed a mega-extension during the spring, though it could also be a reflection of the upcoming labor negotiations in the offseason.
Perhaps in anticipation of that, teams are trying to lock in the cost of their young, promising players. And those players are agreeing to long-term financial stability ahead of what could be a contentious offseason.
