Alonso said the idea for a horse with a hat and Mets warm-up jacket on its torso came from current batter coach Hugh Quattlebaum. It was in the bargain for the first time on Friday.
Earlier this year, after the Mets got out of the slump, players began to casually refer to a new batting approach coach named “Donnie Stevenson.” Initially, it was reported that Alonso was dressed as a fictional character to unleash his teammates. Later, players began wearing “Donnie Stephenson” T-shirts, which show a bulging man wearing a headband and sunglasses. More recently, a character believed to be played by actor Brett Azar has appeared in several Mets games, and Alonso took pictures with him. But Stevenson has been hiding since the last match before the All-Star Break. The home run horse may have changed.
