SHANE LOWRY hass issued a hilarious message to Rory McIlroy ahead of the third major the year. The PGA Tour duo will tee it up alongside one another at the notoriously hard Oakmont Country Club. Their group also sees their Ryder Cup pal Justin Rose join the high-profile trio with the Masters runner-up. Lowry and McIlroy will tee off in the year's third major at 12.40pm Irish time, starting on the tenth tee. Their second round will commence at 6.25pm Irish time, on the first box. Shane Lowry and Rory McIlroy also teed it up together on the back nine at 6:40 am this morning, and with another practice round planned for Wednesday. The Irish pair will be spending plenty of time together in the lead-up to the U.S. Open. Lowry, who finished T2 at the same course after the 2016 U.S. Open, reckons the pair will be sick of one another by the week's end. He hilariously told the Irish Independent: “We’re practising tomorrow morning again, so we’ll be sick of each other by Friday, but hopefully we both play well and give ourselves a run at the weekend.” Lowry reckons that sharing the fairways with two familiar Ryder Cup teammates could prove to be a boost as they can feed off one another. He added: “I played with Rory in the first two rounds of Bay Hill this year and I was well up there. “So, yeah, I love playing with Rory, and I think we’ve got a great group there with Justin Rose as well. “Everybody gets on very well, but when you’re out there, there’s not too much chit-chat. "There’s not much fun out there. But it will be nice.” All the action gets underway from Thursday, LIVE on Sky Sports Golf.
