Mike Trout’s Old Hickory MT27* Maple Bat
Mike Trout has been swinging Old Hickory bats since the day he busted into the Big Leagues and that hasn’t changed. His bat’s model number has though. It was originally the J143M, which Old Hickory describes here:
“The J143M has a medium barrel with a short taper to a thin handle that runs straight into the knob. The J143M offers an extremely long barrel and a large sweet spot.”
The J143M bat is available, as is his namesake model, the MT27. Trout’s game model bat, the MT27 has an asterisk next to it though, and we’re told its because the retail model is more like a T141, not the J143 that Trout actually swings.
