The piece has a first tapered region terminating at the first end and a second tapered region terminating in the second end. Within each of the first and second tapered regions, the first and second side edges converge. The piece also includes a main section located between the first and second tapered regions. The first and second side edges are parallel to one another along the length of the main section. A back surface of the polymeric film includes an adhesive for adhering the polymeric film to the baseball bat and to any underlying polymeric film. ## Claims ### Claim 1 A protective wrap for application to a wooden baseball bat to prevent the release of fragments should the baseball bat shatter during use comprising: an elongated piece of polymeric film that has a first end and an opposite second end, a front surface, an opposite back surface, a first side edge, and an opposite second side edge, the piece having a first tapered region terminating at the first end and a second tapered region terminating in the second end, wherein within each of the first and second tapered regions, the first and second side edges converge and wherein the piece includes a main section located between the first and second tapered regions and the first and second side edges are parallel to one another along the length of the main section; and wherein the back surface includes an adhesive for adhering the polymeric film to the baseball bat and to any underlying polymeric film. ### Claim 2 (depends on 1) The protective wrap of claim 1, wherein each of the first and second ends comprises a rounded end. ### Claim 3 (depends on 1) The protective wrap of claim 1, wherein within the first tapered region, the first side edge comprises a beveled edge and the second side edge comprises a straight edge that extends the length of the main section; and wherein within the second tapered region, the first side edge comprises a straight edge that extends the length of the main section and the second side edge comprises a beveled edge. ### Claim 4 (depends on 1) The protective wrap of claim 1, wherein the piece has a maximum thickness in the main section and a minimum thickness in the first and second tapered regions, the minimum thickness being 50% or less of the maximum thickness. ### Claim 5 (depends on 4) The protective wrap of claim 4, wherein the maximum thickness is about 1 inch and the minimum thickness is about 0.5 inch. ### Claim 6 (depends on 1) The protective wrap of claim 1, wherein the polymeric film is formed from polymers selected from the group consisting of polyurethanes, polyesters, polyethylenes, polypropylenes and polyamides. ### Claim 7 (depends on 1) The protective wrap of claim 1, wherein an angle defined between the first and second side edges within at least one of the first and second tapered regions comprises about 10 degrees. ### Claim 8 (depends on 1) The protective wrap of claim 1, wherein the adhesive layer is pre-applied to the back surface and includes a removable protective release covering the adhesive layer and the polymeric film is of a type that allows the piece to be rolled. ### Claim 9 (depends on 1) The protective wrap of claim 1, wherein the piece has symmetry about a central longitudinal axis that extends the length of the piece but has asymmetry about a central transverse axis that extends between the first and second side edges at a midpoint of the piece. ### Claim 10 A method for treating a wooden baseball bat to prevent the release of fragments should the baseball bat shatter during due comprising the step of: wrapping an elongated piece of polymeric film around at least a transition portion of the baseball bat by wrapping, at a start location along the bat, in a spiral motion such that the polymeric film is wrapped completely around the bat to define an initial winding and then wrapping the polymeric film about the bat to form a series of successive windings with the polymeric film of each winding never completely overlapping an underlying winding and terminating the successive windings at an end location along the bat so as to form a two layer wrap around at least the transition portion of the baseball bat, wherein the piece has a first side edge, an opposite second side edge, a first tapered region terminating at a first end thereof and a second tapered region terminating in an opposite second end thereof, wherein within each of the first and second tapered regions, the first and second side edges converge and wherein the piece includes a main section located between the first and second tapered regions and the first and second side edges are parallel to one another along the length of the main section, and wherein the back surface includes an adhesive for adhering the polymeric film to the baseball bat and to any underlying winding of polymeric film. ### Claim 11 (depends on 10) The method of claim 10, wherein each of the first and second ends comprises a rounded end. ### Claim 12 (depends on 10) The method of claim 10, wherein within the first tapered region, the first side edge comprises a beveled edge and the second side edge comprises a straight edge that extends the length of the main section; and wherein within the second tapered region, the first side edge comprises a straight edge that extends the length of the main section and the second side edge comprises a beveled edge. ### Claim 13 (depends on 12) The method of claim 12, wherein the polymeric film is positioned relative to the baseball bat such that the first side edge of the first tapered region is located on the left and is aligned with a first locating mark formed at the first location, the first tapered region being constructed such that the polymeric film lines up properly after one revolution about the bat, which forms the initial winding, and then automatically angles a remaining length of the polymeric film to achieve an about 50% overlap. ### Claim 14 (depends on 13) The method of claim 13, wherein the first locating mark is a line that is perpendicular to a central longitudinal axis of the baseball bat that extends along a length thereof. ### Claim 15 (depends on 10) The method of claim 10, wherein the polymeric film of each successive winding overlaps the underlying winding by about 50%. ### Claim 16 (depends on 10) The method of claim 10, wherein the first end of the polymeric film is disposed at the first location and the second end of the polymeric film is disposed at the second location. ### Claim 17 (depends on 12) The method of claim 12, wherein a first end of the two layer wrap is defined by the beveled first side edge of the first tapered region and an opposite second end of the two layer wrap is defined by the beveled second side edge of the second tapered region. ### Claim 18 (depends on 10) The method of claim 10, wherein the piece of polymeric film has symmetry about a central longitudinal axis that extends the length of the piece but has asymmetry about a central transverse axis that extends between the first and second side edges at a midpoint of the piece. ### Claim 19 (depends on 10) The method of claim 10, wherein a barrel portion of the bat remains uncovered by the polymeric film.
