We are witnessing a dynasty the Major Leagues haven't seen in decades, and Roki Sasaki is at the center of it. After helping the Los Angeles Dodgers to the first back-to-back championship since the New York Yankees did it at the turn of the century, Roki Sasaki penned an autograph on this Rawling batting helmet, along with three inscriptions for a personal touch: "25 WS Champs," "Back 2 Back," and "I Bleed Dodger Blue." This one-of-one collectible is the perfect piece to display in your fan cave as you look back on this championship.
