Rory McIlroy's driver is his most potent weapon, according to analyst Alan Shipnuck, who believes it makes him superior to Scottie Scheffler.
What happened at the U.S. Open?
Rory McIlroy posted a 1-over 69 in the opening round at Shinnecock Hills, briefly holding the lead after an eagle on the par-5 fifth.
He dropped shots on the final two holes, signing his card at one under, in a controlled performance.
Why it matters for Rory McIlroy
McIlroy's driver has been a recurring storyline all season, with him leading the PGA Tour in Strokes Gained (SG): Off the Tee in 2026.
However, his driving has cost him dearly when it misfires, as seen at the PGA Championship at Aronimink in May.
What comes next for Rory McIlroy?
Alan Shipnuck's observation about Scottie Scheffler looking edgy proved telling, as Scheffler finished in a tie for fourth at the U.S. Open.
Rory McIlroy finished the week at six over, admitting Shinnecock "won the battle" over him, but Shipnuck's point about his composure under pressure remains.
And McIlroy's ability to attack the golf course, with his driver being the most potent weapon, makes him a dangerous opponent.
But McIlroy has transformed his approach to major championships earlier this season, which could lead to better results in the future.
So McIlroy's performance at the U.S. Open was a mixed bag, with both positives and negatives to take away.
As of the 2026 U.S. Open, McIlroy has shown he can compete with the best, including Scottie Scheffler, who celebrated his 30th birthday in the final round.
