Two big-league seasons. Two All-Star selections. One signature.

In 2025, Jacob Misiorowski became the fastest player in MLB history to be named an All-Star — just five games into his career. In 2026, he erased every argument: at the time of his selection to the National League squad for the All-Star Game in Philadelphia, he led the Majors in ERA, strikeouts and WHIP. An All-Star in each of his first two seasons isn't a hot start. It's an arrival.

This is the official Rawlings 2026 MLB All-Star Game Baseball — the commemorative ball produced for the Midsummer Classic, stamped with the official Philadelphia 2026 All-Star Game logo and finished in the event's red-and-navy stitching. Misiorowski signed it clean: a bold blue-ink autograph, no inscription, nothing between his signature and the ball built for baseball's biggest summer stage.

Signed. Witnessed. Certified.

Jacob Misiorowski is an LGC SportsGraphing Exclusive Athlete. His autograph was witnessed in person by a PROVA authenticator at a private signing, a PROVA SmarTag was applied to the ball as he signed it, and a PROVA Witnessed Certificate of Authenticity comes with it — a documented chain from his hand to your display shelf.

The debut ball marks where it started. The All-Star ball proves how fast it's climbing. For the Brewers fan building a Misiorowski collection, this is the 2026 chapter — captured on the ball made for that game.
