PITTSBURGH — Baseball’s most highly-regarded prospect will make his major league debut this Friday when the Pittsburgh Pirates face Baltimore in their home opener.
According to a source with knowledge of the team’s plans, the Pirates will promote 19-year-old shortstop Konnor Griffin, who is widely considered the sport’s premier prospect. The source requested anonymity since the roster decision has not been formally announced.
Griffin’s arrival in the majors was never a question of if, but rather when, and his blazing start at Triple-A Indianapolis provided the answer. In just 16 at-bats, the teenager posted a remarkable .438 batting average while collecting three doubles, driving in one run, and swiping three bases.
Standing 6-foot-3, Griffin was selected ninth overall in last year’s amateur draft and has advanced rapidly through Pittsburgh’s minor league system. During the 2025 season, he compiled impressive numbers across Single-A and Double-A levels, hitting .333 with 21 homers, 94 RBIs, and 65 stolen bases over 122 games.
The young prospect participated in Pittsburgh’s major league spring training and nearly made the opening day roster. Despite launching three home runs during exhibition play — more than any teenager in spring training over the past 20 years — Griffin also struggled with strikeouts, fanning more than a dozen times.
Pittsburgh began the season with Jared Triolo manning shortstop and Nick Gonzales at third base. Griffin’s promotion will likely shift Triolo, who won a Gold Glove as a utility player, to third base.
Although the Pirates have discussed a long-term contract extension with Griffin that would cover his arbitration-eligible years, the source indicated his promotion is based purely on performance. The organization views Griffin as their strongest option at shortstop.
Griffin joins a Pirates squad that stands 3-3 after winning two of three games in Cincinnati. The team boasts one of baseball’s most promising young pitching staffs, headlined by defending Cy Young Award winner Paul Skenes, who earned his first win of the season on Wednesday.
Pittsburgh addressed their offensive struggles during the offseason by acquiring All-Star second baseman Brandon Lowe through a trade and signing free agents Ryan O’Hearn and Marcell Ozuna. Lowe has already connected for three home runs this season, contributing to the Pirates’ 10 homers through six games — tied for the major league lead with Los Angeles Angels. Last season, Pittsburgh finished with the fewest home runs in baseball by a significant margin.
