In this collection, every hat is accurate to what the players wear on the field. Known as On-field hats, the World Series patch is on the left side of the cap, just like it would be for players. On a regular cap that is not on-field, the patch would be on the right, with the New Era being on the left. Since this is on-field though, there is no New Era logo. Each of the MLB World Series On-Field Side Patch Gray Under Brim Fitted Hats in this collection were brought back for a reason. Each year having a moment or historical event within that series. For example, with the New York Yankees 2020 World Series Side Patch Gray Bottom Fitted Cap
, this was the final year in the Yankees winning three titles in a row, a feet only done by one other team. This exact same series is also historical because this series was the one and only time that the Yankees and Mets met in the World Series. Being from the same city, everyone dubbed this the Subway Series. The New York Yankees 2000 Subway Series Side Patch Grey Bottom Fitted Cap
perfectly captures the rivalry between the two teams. Even though the Yankees won the series, this will always be considered one of the most entertaining World Series ever. The Arizona Diamondbacks 2001 World Series Side Patch Gray Under Brim Fitted Hat
is another homage to the historical importance of this series. With the Diamondbacks franchise only being four years old at the time of winning. The Diamondbacks are now one of the youngest franchises to ever win a world series.
