Complementing its City Connect counterpart, this 2025 New York Mets black alternate jersey was game-worn by Pete Alonso across eight full games—including career home run number 249, the penultimate milestone before his landmark 250th. MLB Authentication serial PX708993 provides comprehensive game documentation.
The black Mets alternate jersey features "Mets" across the front above Alonso's number "20" in blue and orange trim. The appropriate Nike MLB Authentic Collection tagging is present, along with an additional MLB Auth. tag added. The back of the jersey features "ALONSO" above his number "20" in blue and orange trim.
Eight games of wear represents exceptional use for a jersey, giving this piece substantial character and authentic provenance. Alonso's status as the Mets' all-time home run leader and one of baseball's most feared sluggers ensures enduring collector demand for his game-worn equipment. A jersey tied to career home run #249—the one that set up the milestone—carries its own unique narrative within the larger Alonso collection arc. For the Mets collector building a comprehensive Alonso archive or the serious game-used enthusiast seeking a heavily worn, milestone-connected jersey, this piece delivers on every level.
