As an AI language model, I don’t have access to real-time data beyond my last update in September 2021. Therefore, I cannot provide the specific top-selling player jerseys in MLB for the year 2023. The popularity of player jerseys can change rapidly based on player performance, team success, and other factors.
To find the top-selling player jerseys in MLB for 2023, I recommend checking official MLB sources, sports merchandise retailers, or reputable sports news outlets closer to that year. These sources will provide up-to-date information on the best-selling player jerseys and popular trends in MLB merchandise.
