The Butler Bubble is home to the Bulldog men's and women's tennis teams and is used as an indoor practice facility for the Butler baseball, football and soccer teams. All of the Butler tennis teams' home matches during the winter and early spring take place inside the bubble, which is located behind Hinkle Fieldhouse off of 52nd Street.
The Bubble was originally constructed at the far west end of the Hinkle Fieldhouse parking lot, but was relocated to along the right field line of Bulldog Park after the original plot was broke for the construction of the new Health and Recreation Complex in the summer of 2005.
The Bubble houses four hard-surface tennis courts as well as additional room for storage of equipment for both tennis teams. The bubble itself is supported by higher air pressure inside and is permanently fixed over the courts.
