Konnor Griffin, MLB's top prospect, called up by Pittsburgh Pirates

Konnor Griffin, the top prospect in Major League Baseball, is set to be called up by the Pittsburgh Pirates.

The team announced the news on Thursday, one day before the team's home opener against the Baltimore Orioles. Griffin is set to make his Pirates debut at PNC Park for the game. 

Who is Konnor Griffin?

Griffin was named MLB Pipeline's new No. 1 prospect in July 2025. 

The highly touted 19-year-old prospect was reassigned to minor league camp during spring training. Last month, Pirates manager Don Kelly said the decision to leave Griffin off the season-opening roster was "extremely difficult." He had a .171 batting average, four home runs and nine RBIs in 16 spring training games. 

Griffin was selected No. 9 overall by Pittsburgh in the 2024 draft out of Jackson Preparatory School in Flowood, Mississippi.

Konnor Griffin's contract

The Pirates are reportedly in negotiations to get Griffin signed to a long-term contract. ESPN insider Buster Olney reported on Thursday that Griffin's deal is worth $140 million over nine years, though the contract has not been finalized. 

When will Konnor Griffin make his debut?

If Griffin makes his debut on Friday, he would be the first teenage position player to debut since Juan Soto in 2018.

First pitch for the Pirates' game on Friday against Baltimore is set for 4:12 p.m. at PNC Park.
