In an interview with the Tampa Bay Times at Rays Fan Fest on Saturday, Morton said he was "aware of the banging" Astros players were using to warn hitters of what kind of pitch was coming during the 2017 season.
"Personally, I regret not doing more to stop it," Morton said. "I don't know what that would have entailed. I think the actions would have been somewhat extreme to stop it. That's a hypothetical."
However, he admitted that the scandal has damaged the game of baseball and took responsibility for his role in it.
"Because what's wrong is wrong," Morton told the Tampa Bay Times. "And I'll never be absolved of that."
Morton pitched for the Astros in 2017 and 2018, going 29-10 with a 3.36 ERA in the two seasons. He posted a 1.74 ERA across 10⅓ innings against the Dodgers in the 2017 World Series that Houston went on to win.
Morton told the Times that the perception of that championship was "negatively affected, at minimum."
"There are moments during the World Series that will always be special to me, that won't be 'tainted.' But certainly that's justified, that's a justified perception to have, and what people have expressed."
