What is the Phantom tag?

The "Phantom tag" refers to a specific norm in baseball, particularly during a double play, where the infielder (such as the shortstop or second baseman) does not need to physically touch second base with their foot. Instead, they only need to be close to the base. This practice is generally accepted for safety reasons, to prevent injury to the infielder while making the pivot. The idea is to reduce the risk of collisions or injuries without overly scrutinizing the exactness of the play, even in the context of replay reviews 1.
