NEW YORK (AP) — Major League Baseball has told Yankees pitcher Nelson Cortes that his pump fake pitch to Cleveland’s Andrés Giménez is against the rules.

Known for his deceiving leg kicks and windups, Cortes added another trick in his repertoire with a funky move to Giménez in the second inning last Sunday. He faked a throw by waving his left arm at Giménez, then raised a knee before finishing a pitch that Giménez fouled off.

“My thought was that doesn’t feel legal, but pretty funny, I think the guy fouled it off,” Yankees manager Aaron Boone said Saturday. “It would have been funnier it he punched him out. It’s just kind of one of the things he brings to the table that’s I think fun for the game and I think is part of what makes him unique and special -- but can’t do the pump fake anymore.”

Cortes would be charged with an automatic ball should he try the move again.
