Sources: Konnor Griffin agrees to 9-year, $140M deal with Pirates - ESPN

Rookie shortstop Konnor Griffin and the Pittsburgh Pirates are in agreement on a nine-year extension, the team announced, locking up the top prospect in baseball less than a week after his major league debut.

The deal is worth $140 million, sources told ESPN's Jeff Passan and Buster Olney, the largest guarantee in Pirates history as well as for a player in his rookie season.

Griffin, 19, was the first teenage position player to debut since Juan Soto in 2018 when he took over starting shortstop duties for the Pirates before their home opener Thursday. The contract buys out three potential years of free agency for Griffin, who is regarded throughout the industry as a franchise-level talent.

«Signing Konnor is a meaningful commitment to this team, this city and our fans. It reflects our belief in Konnor, in this season's club and in the future of our organization,» said Pirates chair Bob Nutting in a statement. «Konnor represents everything we value in a player — exceptional talent, strong character, a team-first mentality and a maturity that stood out to all of us from the beginning. He is the right person, from the right family. This is another important step in the work we have been doing to build a winning team, for this year and going forward.»

After negotiating on a potential extension throughout the spring, Griffin and the Pirates this week worked out the details on a framework reported earlier by ESPN's Buster Olney. By waiting to finalize the deal until after Griffin's debut, Pittsburgh is eligible to reap a first-round draft pick through the Prospect Promotion Incentive should Griffin win Rookie of the Year or finish in the top three of MVP voting in 2026, 2027 or 2028.
