New York Mets rookie sensation Pete Alonso said Tuesday he is teaming up with Amazin’ Memorabilia to sell his autographed gear, including jerseys, home run baseballs, bats and batting gloves on an exclusive basis for charity, with the Mets donating net proceeds to the charitable Mets Foundation.

Alonso already has set the National League rookie home run record with 43 and is closing in on Aaron Judge’s all-time rookie home run record of 52.
