Formidable US Open layout to test field of 156, Rahm and McIlroy among top favorites

BROOKLINE, US: A hotly anticipated US Open starts Thursday that will test the world’s top golfers over a formidable layout at a historic setting with a splash of controversy as well.

Defending champion Jon Rahm, four-time major winner Rory McIlroy, top-ranked Masters champion Scottie Scheffler and two-time major winners Justin Thomas and Collin Morikawa lead fan and oddsmakers favorites at The Country Club.

In addition to creating dense rough and lightning-fast greens, the US Golf Association ensured drama by allowing players from the upstart LIV Golf Series to compete rather than ban them as the PGA Tour did.

As a result, US stars Dustin Johnson, Phil Mickelson, Patrick Reed and Bryson DeChambeau are among the LIV Golf standouts teeing off in a unique sub-plot to the quest for a major title — the first LIV-PGA showdown.

“Who knew we loved all this drama?” Morikawa said. “It becomes a distraction and you don’t want to be focused on this or that. We’re here to win the US Open.”

Mickelson, who turns 52 on Thursday, would complete a career Grand Slam with a victory after a record six runner-up efforts, and break his own mark as the oldest major winner.

“I’m excited to be back in this incredible championship that has eluded me,” Mickelson said.

Boston fans famously heckled Europe in a 1999 US Ryder Cup fightback victory and could offer more barbs.

“Whether it’s positive or negative toward me directly, I think it’s going to provide an incredible atmosphere,” Mickelson said.

Tiger Woods, making a comeback after severe leg injuries suffered in a car crash 16 months ago, skipped the US Open to
