A sprinkler includes a compartment that surrounds its riser portion in an offset or asymmetrical configuration. More specifically, the distance of the compartments walls from those of the riser vary (i.e., increase or decrease) at different locations surrounding the riser. Put another way, the riser is closer to one side of the compartment than other sides of the compartment. This non-concentric configuration allows larger components to fit inside the compartment than would otherwise fit if the riser was symmetrically surrounded by the compartment.

Described herein is a bounce-reducing cover assembly that is positioned on the top of the cover and riser of a sprinkler to achieve a similar golf ball bounce characteristic as typical golf course turf. The cover assembly has a top surface that is composed of a plurality of vertical fingers or posts, which help achieve the desired bounce characteristics with a golf ball. Specifically, these fingers are flexible and provide some “give” so as to absorb some of the force from an incoming golf ball. Depending on the durometer of the material, size of the fingers, and spacing of the fingers, different bounce characteristics can be achieved.
