Rory McIlroy admitted to feeling "a little rusty" after the first round of the Truist Championship in Philadelphia, where he finished five shots behind leader Keith Mitchell. McIlroy, a four-time champion of this event, carded a four-under-par 66 at the Wissahickon Golf Course, placing him tied for 25th.

Despite his rustiness, McIlroy managed six birdies and two bogeys. "I drove the ball pretty well. I can certainly tidy a few things up, but overall a decent day," he commented. This performance comes as he prepares for next week's US PGA Championship, where he aims to continue his recent success after winning the Masters last month.

Keith Mitchell leads the tournament with an impressive nine-under-par 61, one stroke ahead of Denny McCarthy. Mitchell's round included a strong finish with four consecutive birdies. Other notable performances include Shane Lowry at six under and Aaron Rai at five under.

McIlroy remains optimistic as he approaches the US PGA Championship, expressing "nothing but positive vibes" after ending his long wait for a title at Augusta National. His recent form suggests he could be a strong contender in the upcoming major.
