Rory McIlroy out of running at US Open after back-nine 40

Rory McIlroy's hopes at the US Open were effectively ended after he carded a back-nine score of 40, a significant collapse that pushed him out of contention for the title. The poor back-nine performance likely came as a major disappointment given McIlroy's stature as one of golf's top players. The result means he will not be challenging for the championship heading into the later rounds of the tournament.
