"Patrick came up to say hello, and I didn't really want him to," McIlroy said Wednesday.
McIlroy was asked about reports that the American threw a tee toward him. The four-time major winner said he didn't see or feel anything.
"But apparently that's what happened," McIlroy said. "And if roles were reversed and I'd have thrown that tee at him, I'd be expecting him [to file] a lawsuit."
