After Yordan Álvarez snapped his Louisville Slugger i13 bat like a twig after a strikeout, he went to the Chandler YA143M, which we’re assuming is the Mike Trout/JD Martinez bat model (Old Hickory J143M). According to Old Hickory, the J143M bat is a medium diameter, extremely long barrel with a short taper to a thin handle that runs right in to the knob. Álvarez also swung this bat in batting practice.
While Chandler doesn’t offer Álvarez’ exact model, you can shop Chandler wood at JustBats.com (the AP5 is probably the closest alternative).
Yordan Álvarez’ bat measurements: 34 inch, 31 ounce cupped
