This BWP (Barnstable Wood Products) RC271 premium maple professional model baseball bat was game-used by Fernando Tatis Jr. during the 2017 season with the San Diego Padres minor league organization — predating his explosive MLB debut by two years — and carries his personal autograph. The bat is a BWP RC271 in premium maple 33.5-inch specification, finished in a two-tone treatment: the handle and lower barrel present in natural blonde/unfinished maple, while the upper barrel transitions to deep navy blue/black, with the BWP logo in gold lettering. The barrel face carries "Tatis Jr. / Premium Maple 33.5 / [serial #]1617" in silver/gold print.

Tatis Jr. has signed the bat in silver marker on the upper barrel area. The bat exhibits clear and substantial evidence of professional game use — the handle shows prominent pine tar residue and dirt staining, the blonde handle wood has taken on a deep caramel coloring from handling, and the barrel presents with ball contact marks and surface wear. A PSA/DNA hologram is affixed near the handle, and the overall use pattern reinforces PSA/DNA's GU 8.5 game-use grade. A PSA/DNA sticker cert covers the autograph separately. Pre-MLB Tatis Jr. game-used equipment is extremely rare to market, and this 2017 minor league bat represents a foundational piece from one of the game's most dynamic and commercially significant stars.
