Batting practice tee

A batting practice tee comprising:

• a base assembly including a continuous uninterrupted channel fixedly mounted to said base assembly, said channel being defined by first and second sidewalls extending generally downwardly, a bottom surface generally orthogonal to the sidewalls, and a top portion having an opening, said channel including an inner-locking guide rail fixedly disposed within said channel along said bottom surface of said channel and said first sidewall between a first termination point and a second termination point of said channel, said inner-locking guide rail protruding into a space defined by said channel so that a width of a lower space of said channel is smaller than a width of an upper space of said channel;
• said inner-locking guide rail forming a generally rectangular profile within said channel, a height of said inner-locking guide rail being a portion of a height of said first sidewall and a width of said inner-locking guide rail being a portion of a width of said bottom surface;
• and
• a tube assembly for holding a ball, said tube assembly removably coupled to said channel and being rotatable between an open position and a closed position, said tube assembly including a slidable device disposed about a rod of said tube assembly, a head of said rod fitting within the lower space of said channel and said slidable device fitting within the upper space of said channel so that a portion said slidable device is positioned above said-inner-locking guide rail, said slidable device being wider than the lower space of said channel,
• wherein, in said open position, said tube assembly is removable from said channel and movable throughout said channel, and
• wherein, in said closed position, said tube assembly engages said inner-locking guide rail to secure said tube assembly to a location along said channel, said tube assembly holding said ball above said location.
