Abstract
Abstract A batting practice apparatus includes a batting cage which has a relatively small, closed rear end and a relatively large, open front end. The batting cage is located above a level playing surface and extends over a batting position which is proximate to the closed rear end, and remote from the open front end. A vertical retaining screen is located in front of the open front end of the batting cage and extends in an arc thereabout. Indicia on the retaining screen define a plurality of horizontally extending bands, one above another. Baseballs hit from the batting position through the open front end of the batting cage will either strike the ground before reaching the retaining screen, or strike the retaining screen without first hitting the ground. The vertically adjacent horizontal bands indicate that a ball striking the retaining screen without first hitting the ground is classified as a single, double, triple or home run. The height of the retaining screen is just great enough to stop batted balls which barely clear the forward overhead edge of the batting cage. Likewise, the retaining screen extends laterally only a sufficient distance to stop batted balls which barely clear the forward edges of the sides of the batting cage.

Claim 5
Dependent Claim
49 words
A baseball batting practice system according to claim 1 wherein said indicia designate the lowest of said bands as a single, the next lowest of said bands as a double, the next lowest of said bands as a triple and the highest of said bands as a home run.
Claim 6
Dependent Claim
74 words
A baseball batting practice system according to claim 1 wherein the dimensions of said batting cage and retaining screen and the distance of separation therebetween are such that all straight lines extending from a location no less than one foot above said playing surface at said batting position through said open end of said batting cage intersect said retaining screen unless they intersect said playing surface between said batting position and said retaining screen.
Claim 7
Dependent Claim
79 words
A baseball batting practice system according to claim 1 wherein the dimensions of said batting cage and said retaining screen and the distance therebetween are such that all straight lines extending from a location no less than one foot above said playing surface at said batting position and which pass through said open end of said batting cage and which fail to intersect said playing surface between said batting position and said retaining screen, all intersect said retaining screen.
Claim 8
Dependent Claim
39 words
A baseball batting practice system according to claim 1 wherein said retaining screen is constructed of a plurality of vertical posts spaced laterally from each other and of fabric mesh screen material attached to said posts and extending therebetween.
