LOUISVILLE, Ky. — The divide between golf’s two biggest names just keeps growing.

There’s Rory McIlroy, shooting another round in the 60s and looking very much like the man to beat at the PGA Championship.

Then there’s Tiger Woods, spraying shots all over Valhalla and now most concerned with making it to the weekend.

Clearly, they are two players heading in very opposite directions.

“I’m really happy with everything,” said McIlroy, who opened with a 5-under 66 on Thursday despite one bad swing that led to a double bogey.

Woods can’t get anything going.

Just four days after withdrawing at Firestone because of back pain, he shot a 3-over 74 that included only one birdie.

He faced a daunting nine-shot deficit heading to the second round. Lee Westwood, Ryan Palmer and Kevin Chappell all shot 65 .
