Pete Alonso Signed Jerseys
Pete Alonso's #20 New York Mets jersey has become synonymous with tape-measure power and the kind of charismatic energy that fills stadiums. He wore it through a record-breaking rookie campaign of 53 home runs, three Home Run Derby championships, and over 200 career home runs that have established him as the face of the Mets franchise. After signing a free-agent deal to stay in New York in 2025, Alonso cemented his long-term connection to the blue and orange, making his Mets jersey a staple of the franchise's current era. A signed Polar Bear jersey is a tribute to one of baseball's most exciting active sluggers.
