Twitch, which made its name streaming video games and virtual e-sports contests, is now going to broadcast a physical sport — Mexican professional wrestling. The Amazon-owned San Francisco company said Wednesday it will live broadcast Saturday’s “Triplemania XXV,” an annual tournament from Lucha Libre AAA Worldwide, one of Mexico’s oldest wrestling promotion companies. Lucha Libre Worldwide will have dedicated Twitch channels, one in Spanish and one in English, that will stream a pre-show marathon starting Thursday afternoon.
