Keith Hernandez's game-used Rawlings Adirondack Big Stick 460B personal model baseball bat, used during the 1986 National League Championship Series (NLCS) between his New York Mets and the Houston Astros. The ash bat measures 34.25″ long, weighs 31 ounces, and is engraved on the barrel with his name and team ("Keith Hernandez, New York Mets"), signed to the left in blue felt tip. His initials ("K.H.") are also stamped into the knob, which has his number "17" written in black felt tip. The bat shows outstanding evidence of use, including a repaired handle crack, heavy coat of pine tar, and numerous ball and stitch marks on the barrel. Accompanied by a letter of grading and authenticity from PSA/DNA, grading it as "PSA/DNA GU 9." The Mets' star first baseman hit .269 in the 1986 NLCS, driving in three runs to help propel the Mets to the memorable 1986 World Series; there, his bat was largely silent until the game seven clincher, when he drove in three runs to lead the Mets to victory.
