The Oxy patch on the Astros uniform is a circular patch on the left sleeve of the jersey that reads "Oxy" in big, red block letters outlined in blue. Oxy is short for Occidental Petroleum, a multinational oil and gas exploration and production company based in Houston, Texas. The company has been a sponsor of the Astros for more than a decade. In February of 2022, the Astros announced a new sponsorship deal with Oxy to feature their logo on the sleeve of the Astros uniforms. The exact terms of the Astros’ deal with Oxy have not been disclosed. The Oxy patch will be featured on the Astros jersey sleeve throughout the regular season and any Postseason games. The only exception will be two games where the logo will be gold instead to match the coloring of the 2022 World Series champions’ uniforms. The Astros are among the MLB teams that have incorporated a jersey patch into their uniforms, and these sponsorship deals have become increasingly commonplace within baseball.
