Houston Sports Park is a multi-purpose sports and entertainment facility in the Five Corners District of Houston, near the neighborhood of City Park. It houses Sabercats Stadium, training fields, and medical and athletic facilities spread across a large campus along the South Freeway at Airport Boulevard.
Houston Sports Park is the training ground for the Houston Dynamo, Houston Dash, and their academy teams, and it is the home venue for the Houston SaberCats of Major League Rugby. The Methodist Center for Sports Medicine on-site also serves the Houston Texans, Astros, Rodeo, and Ballet.
Construction began in 2011, with Phase One now completed and in use. The City of Houston assembled the land throughout 2008 and re-platted it as "Houston Amateur Sports Park" the following year. A municipally owned corporation, the Houston Amateur Sports Park LGC, was created on the 9th of November 2011 to build and manage the facility.
Sabercats Stadium, originally called Aveva Stadium, cost $15.25 million to build. The City of Houston contributed $3.2 million of that total on the 7th of February 2018. The stadium was completed in April 2019 and holds 4,000 spectators.
Phase Two will add seven more lighted fields, a restroom pavilion, misting stations, picnic facilities, trails, a playground, and additional parking. The estimated cost to complete the full complex is $12 million, and fundraising for Phase Two is currently underway.
The park was originally planned to give the Houston Dynamo a permanent training facility after the team relocated from San Jose in 2005. The Dynamo's ownership group, Anschutz Entertainment Group, wanted both a stadium and a training ground, and the city began acquiring land in south Houston by 2008 to meet that need.
