The “OXY” patch on the Houston Astros uniform is an advertising logo for Occidental Petroleum , a large energy company that goes by the shorthand Oxy and is headquartered in Houston.

What the OXY Patch Is

  • The patch shows the Oxy corporate logo: the word OXY in red letters inside a white circle with blue elements.
  • It appears on the sleeve of the Astros’ jerseys as part of Major League Baseball’s program allowing uniform sponsorship patches.

Why It’s on the Astros’ Uniform

  • The Astros and Occidental Petroleum signed a multi‑year jersey sponsorship deal (reported as a seven‑year agreement running into the late 2020s).
  • Because Oxy is a major Houston‑based company, the partnership is framed as a local corporate–team connection that boosts Oxy’s visibility and ties it to the Astros’ brand.

Bigger Trend and Fan Reactions

  • MLB teams have only recently begun adding paid sponsor patches, following trends already common in the NBA and international sports.
  • Some fans see the Oxy patch as just part of modern sports marketing, while others dislike corporate logos on traditional uniforms and debate it on forums and social media.

TL;DR: The OXY patch on the Astros uniform is a sleeve advertisement for Occidental Petroleum (Oxy), a Houston‑based energy company that signed a long‑term jersey sponsorship deal with the team.
