Major League Baseball has officially declared the pump-fake pitch by Yankees pitcher Nestor Cortes against the Cleveland Guardians as illegal, warning that future attempts will result in a penalty.

Nestor Cortes attempted a unique pump-fake pitch during a game against the Cleveland Guardians, which MLB has now ruled as illegal.
The deceptive move involved Cortes waving his arm and raising his knee before completing the pitch, which was initially allowed by the umpire.
Yankees manager Aaron Boone inquired about the legality of the pitch, leading to MLB's clarification that it cannot be used in future games.
Cortes, known for his creative pitching style, expressed humor over the incident, acknowledging the uniqueness of his action.
