Konnor Griffin Set to Make His Major League Debut for the Pirates
The day has finally come for Pirates fans and prospect savants probably much sooner than anticipated as Konnor Griffin, the consensus top prospect in baseball, has been called up to make his big league debut in the Pirates home opener on Friday at 4:12 PM ET.
There was some buzz about Griffin potentially making the big league roster out of spring training, but the likelihood of that happening was pretty slim considering he’s still a teenager without any experience in Triple-A, and his performance at big league camp this spring wasn’t as good as it had been made out to be. However, Griffin opened at Triple-A Indianapolis where he immediately got off to a scorching start, posting a 1.196 OPS and a 238 wRC+ across 21 plate appearances. That was enough for the Pirates to give him the call, especially considering they would be eligible to earn a prospect promotion incentive pick in next year’s draft if Griffin is to win the National League Rookie of the Year here in 2026. He can also earn the Pirates the pick if he finishes within the top three in National League MVP voting in any season prior to his arbitration years. In order for the team to be eligible for the PPI pick, the player has to have logged a full season of service time in their rookie season, hence the “prospect promotion” incentive to encourage teams from manipulating service time to extend their arbitration years.
Griffin won’t turn 20 until April 24th, so he is the first hitter since Juan Soto with the Nationals in 2018 to debut as a teenager. The 6’3”, 220 pound shortstop was drafted ninth overall in the 2024 MLB draft out of Jackson Prep High School in Mississippi. He was the first high school player selected in the 2024 draft, and is the first high school player from the class to make his Major League debut. Including the college players selected in the draft class, he’s just the 11th player to debut from the class.
In hindsight, there’s a good case to be made that Griffin should have been the first overall pick in the 2024 draft, but he did enter pro ball with some question marks. His hit tool was still pretty raw, his swing needed work, and his long-term defensive home was still uncertain which is why he fell to ninth overall. Credit to the Pittsburgh’s player development, because he came out in 2025 looking like a brand new ballplayer in his introduction to pro ball. He advanced as high as Double-A Altoona after spending time at both High-A Greensboro and Low-A Bradenton. In 563 plate appearances between the three levels last year, Griffin hit 21 home runs and stole 65 bases while posting a .333/.415/.527 slash line, good for a .941 OPS and a 165 wRC+. He managed to hold his strikeout rate at 21.7%, a pretty solid mark considering the hit tool risk he was bringing into the organization. On top of the improved offensive ability, Griffin showed the ability to handle shortstop over the course of the season, receiving excellent reviews as a pro defender as he played 89 of his 122 games at the position. There’s still always the possibility he could move to the outfield, but for now, the expectation is that he is going to provide value with the glove from day one.
On top of the promotion, it has been confirmed that Griffin will be the starting shortstop for the Pirates in the home opener against the Orioles on Friday. Griffin’s presence will certainly be refreshing for both the Pirates and their fans as they continue to work their way towards building a winner in Pittsburgh.
