Texas may be getting its second retractable-roofed major league baseball stadium following the Texas Rangers' proposal to build a replacement for their current 22-year-old ballpark, Globe Life Park. While a retractable roof often serves to keep a park dry in cities like Seattle, the Rangers' roof, like the Houston Astros', is meant in part to protect players and fans from the dangerous heat of Texas summers, where it can get to 90 degrees or hotter during the games. The Rangers' lease on Globe Life Park doesn't expire until 2024, but the new ballpark is expected to be in service before then.
