Omega Dubai Desert Classic: After shooting an opening-round 77, withdrew from the Omega Dubai Desert Classic citing back spasms. "Tiger Woods went into a spasm in his lower back fairly late last night, got treatment done early this morning for three and a half hours, but can't get it out," his manager Mark Steinberg said. "He says it's not the nerve, but back spasm, and he can't get the spasms to calm down. He can move around, but he can't make a full rotation in his swing."
Woods was 15 years old and a student at Western High School in Anaheim when he became the youngest U.S. Junior Amateur champion; this was a record that stood until it was broken by Jim Liu in 2010. He was named 1991's Southern California Amateur Player of the Year (for the second consecutive year) and Golf Digest Junior Amateur Player of the Year. In 1992, he defended his title at the U.S. Junior Amateur Championship, becoming the tournament's first two-time winner. He also competed in his first PGA Tour event, the Nissan Los Angeles Open (he missed the 36-hole cut), and was named Golf Digest Amateur Player of the Year, Golf World Player of the Year, and Golfweek National Amateur of the Year.
The Open Championship: Finished T6 at the 147 Open Championship at Carnoustie, his first top-10 in a major since at T6 at the 2013 Open Championship. Week was highlighted by a third-round 66, his lowest round in a major since a 66 in the second round of the 2011 Masters. Was just his second made cut (2018 Masters Tournament/T32) in his last six major starts. Posted rounds of 71-71-66-71, the first time since the 2010 Masters Tournament (T4) he recorded four par-or-better rounds in a major. Paired with eventual-champion Francesco Molinari, entered the final round four shots off the lead. Took the solo-lead at 7-under after nine holes, one ahead of Molinari and Jordan Spieth, but his lead disappeared with a double bogey at No. 11. Bogeyed No. 12 and birdied No. 14 before closing with four pars to finish at 5-under. The finish moved him to No. 50 in the Official World Golf Ranking, returning to the top 50 for the first time since January 2015. The ranking also earned him a spot in the World Golf Championships-Bridgestone Invitational.
Woods collaborated closely with TAG Heuer to develop the world's first professional golf watch, which was released in April 2005. The lightweight, titanium-construction watch, designed to be worn while playing the game, incorporates numerous innovative design features to accommodate golf play. It is capable of absorbing up to 5,000 Gs of shock, far in excess of the forces generated by a normal golf swing. In 2006, the TAG Heuer Professional Golf Watch won the prestigious iF product design award in the Leisure/Lifestyle category.
