A stride section, removably connected to and positioned to extend longitudinally from said generally T-shaped end. A goal post assembly configured to movably position a stride bar across the stride section. The stride bar is positioned as a target for a drive foot of the pitcher to clear a predetermined height during the underhanded pitch. The device is lightweight and portable, useable indoors or on a practice field and is operable for left or right handed pitching. ## Claims ### Claim 1 A pitch training device comprising: a platform configured to support a pitcher performing an underhanded pitch comprising a generally T-shaped end having a raised pitchers rubber configured to support a drive foot of the pitcher during delivery of the underhanded pitch, and a pair of removable heel guides to inhibit rotation of the drive foot; a stride section, removably connected to and positioned to extend longitudinally from said generally T-shaped end, said stride section having a goal post assembly to position a stride bar across said stride section, wherein said stride bar is generally J-shaped and extends vertically from a mounting bracket and has a flexible rod whip portion that extends laterally across said stride section. ### Claim 2 (depends on 1) The pitch training device of claim 1, wherein said platform further comprises an underside having a plurality of platform support members configured to support the platform. ### Claim 3 (depends on 1) The pitch training device of claim 1, wherein said stride bar is adjustable axially along the length of said stride section to accommodate pitchers of different leg length. ### Claim 4 (depends on 1) The pitch training device of claim 1, wherein said goal post assembly is comprised of a semi-circular toothed disc, a mounting bracket and said stride bar. ### Claim 5 (depends on 4) The pitch training device of claim 4, wherein said stride bar is rotatably seated in the mounting bracket, with a fastening clip hooked into female serrations of said semi-circular toothed disc. ### Claim 6 (depends on 5) The pitch training device of claim 5, wherein said stride bar is positioned at a target height and distance from said pitching rubber to force the user's stride foot to elevate while performing the underhanded pitch to improve the user's power generation of the underhanded pitch. ### Claim 7 (depends on 6) The pitch training device of claim 6, wherein said mounting bracket has a spring latch that enables removal and replacement of said stride bar. ### Claim 8 (depends on 1) The pitch training device of claim 1, wherein said platform configured from materials that provide a grip for said drive foot and said stride foot. ### Claim 9 (depends on 1) The pitch training device of claim 1, wherein said materials that provide a grip for said drive foot and said stride foot are petroleum based. ### Claim 10 (depends on 1) The pitch training device of claim 1, wherein said stride section consists of three identical sections, which are detachable and fasten to each other and to said T-shaped end through a connector. ### Claim 11 (depends on 10) The pitch training device of claim 10, wherein said connector has raised nubs and said T-shaped end and said stride section have bottom thru-holes that mate with said raised nubs of said connector to allow for removably connecting said T-shaped end to said stride section. ### Claim 12 (depends on 11) The pitch training device of claim 11, wherein said connector has thru-holes and said T-shaped end and said stride section have bottom raised nubs that mate with thru-holes of said connector to allow for removably connecting said T-shaped end to said stride section. ### Claim 13 (depends on 1) The pitch training device of claim 1, wherein the removable heel guides are conformed to mate with an approximately ½″ tall pitching rubber positioned on the platform underneath the heel guides. ### Claim 14 (depends on 1) The pitch training device of claim 1, wherein said goal post assembly has bottom raised nubs that mate with thru-holes of said stride section to allow for removably connecting said goal post assembly to said stride section. ### Claim 15 (depends on 14) The pitch training device of claim 14, wherein said stride section has bottom raised nubs that mate with thru-holes goal post assembly of said to allow for removably connecting said goal post assembly to said stride section. ### Claim 16 A pitch training device comprising: a platform configured to support a pitcher performing a pitch comprising a generally T-shaped end having a raised pitchers rubber configured to support a drive foot of the pitcher during delivery of the pitch; a stride section, removably connected to and positioned to extend longitudinally from said generally T-shaped end with a goal post assembly comprised of a semi-circular toothed disc, a mounting bracket and a stride bar. ### Claim 17 (depends on 16) The pitch training device of claim 16, wherein said raised pitchers rubber is mated with a pair of removable heel guides to inhibit rotation of the drive foot. ### Claim 18 (depends on 16) The pitch training device of claim 16, wherein the goal post assembly is configured to position the stride bar across said stride section.
