The Pittsburgh Pirates are calling up one of baseball’s best prospects. Shortstop Konnor Griffin will be summoned to make his MLB debut in the team’s home opener Friday, the Pirates announced Thursday. The news comes as the two sides are reportedly working on a long-term extension, which is expected to be in the range of nine years and $140 million, reports ESPN.
Griffin, 20 later this month, will be the first teenager to appear in the big leagues since Elvis Luciano and Juan Soto in 2019. The No. 9 pick in the 2024 Draft skyrocketed through the minors last season, slashing .333/.415/.527 with 21 home runs and 65 steals while climbing from Low Class-A to Double-A. Griffin is 7 for 16 (.438) with three doubles in five Triple-A games this year.
The Pirates gave Griffin a chance to win the shortstop job in spring training, though he stumbled a bit (7 for 41 with 13), specifically swinging through too many pitches in the zone. We ranked Griffin has the third-best prospect in baseball entering spring training. Here’s the write-up:
The rap on Griffin during his amateur days was that he had every tool but the hit tool, the most important of the bunch. It was encouraging, then, to see him ease concerns about his swing-and-miss during his first pro season. He connected on more than 75% of his attempts while showing off the power (he cleared the 114 mph threshold) and speed (he stole 65 bases) combination that gave him a high ceiling. Griffin even kept his strikeout rate under 24% during a 21-game stint in Double-A, suggesting that he wasn’t just feasting on younger pitchers or those with less raw talent. Knowing when to adjust priors is one of the trickiest parts of evaluating players. Given everything about Griffin’s year, it would be silly to ignore how much higher his chances of reaching his star ceiling are now than they were 365 days ago.
It should be noted there are not service time games being played here. Griffin did not spend enough time in the minors this year to push his free agency back. The Pirates will control him from 2026-31, though if the two sides complete their reported nine-year extension, service time will be moot, and Griffin will be tied to the Pirates for nine years.
Griffin is being called up early enough that he will accrue a full year of service time and thus be eligible for a Prospect Promotion Incentive pick. Those are extra draft picks given to teams that do not manipulate the service time of top 100 prospects. To get a pick for Griffin, he would need to win Rookie of the Year, or finish top three in the MVP voting in one of his pre-arbitration seasons between 2026 and 2028. (The extension would also have to be signed after he appears in a game.)
The National League’s rookie class is stacked this year, with Griffin joining righty Nolan McLean (New York Mets), first baseman Sal Stewart (Cincinnati Reds), and second baseman JJ Wetherholt (St. Louis Cardinals) in the Rookie of the Year mix. Others like center fielder Justin Crawford and righty Andrew Painter, both of the Philadelphia Phillies, could factor into the race as well.
The Pirates are 3-3 in the early going. Thursday is a team off-day, then they’ll take on the Baltimore Orioles in Friday’s home opener. Utility man Jared Triolo has started five of the team’s six games at shortstop. Nick Gonzales has started the other.
A nine-year extension would still allow Griffin to become a free agent at age 28.
