Jason Day, Lydia Ko thrive in alternate shot and build 2-shot lead in mixed team

Jason Day and Lydia Ko shot 31 on the back nine in the tougher foursomes format Saturday, giving them a 6-under 66 for a two-shot lead in the Grant Thornton Invitational, the first mixed-team event since 1999. More than posting five birdies on the back nine at Tiburon, Day and Ko managed to avoid mistakes that held so many other teams back. Rickie Fowler and Lexi Thompson put together a dynamic back nine of their own, highlighted by Thompson making a hole-in-one on the par-3 16th hole, the ball taking one hop and disappearing into the hole.

UPDATE 1-Yemen’s Houthis warn they will target all ships headed to Israel

Yemen's Houthi movement said on Saturday they would target all ships heading to Israel, regardless of their nationality, and warned all international shipping companies against dealing with Israeli ports. The Iran-aligned group is escalating the risks of a regional conflict amid a brutal war between Israel and the Palestinian militant group Hamas. The Houthis have attacked and seized several Israeli-linked ships in the Red Sea and its Bab al-Mandab strait, a sea lane through which much of the world's oil is shipped, and fired ballistic missiles and armed drones at Israel.
