HOUSTON (AP) — Houston Astros general manager Jeff Luhnow is refuting some information surrounding the FBI’s investigation into whether St. Louis Cardinals officials breached the team’s computer database.

Speaking to Sports Illustrated, Luhnow shoots down the theory that hackers could access Houston’s system because he didn’t change passwords. He says “that’s absolutely false,” and added that he knows the importance of “password hygiene.”

He also denies he used any of the Cardinals’ intellectual property to create Houston’s database, which they call Ground Control.

Luhnow scoffed at speculation that he was disliked in St. Louis and the hack is about revenge. He says he remains friendly with many people in the organization and that all the top executives with the team attended his wedding in 2012.

He says: “This wasn’t a bad breakup.”
