A bat includes a substantially tubular frame, a substantially tubular body and
at least one sheet. The frame extends along a longitudinal axis. The frame has
a handle portion and a primary hitting portion. The body is coaxially aligned with
the hitting portion of the frame. The sheet has a proximal edge, a distal edge,
and first and second side edges. The sheet is coupled to at least a portion of
one of the hitting portion of the frame and the body such that the first and second
edges each extend from the proximal edge to the distal edge along a path that is
substantially non-parallel with the longitudinal axis.
