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.
Woods' back problems continued to hinder him in 2017. He missed the cut at the Farmers Insurance Open in January and pulled out of a European Tour event in Dubai on February 3. On March 31, Woods announced on his website that he would not be playing in the 2017 Masters Tournament despite being cleared to play by his doctors. Woods said that although he was happy with his rehabilitation, he did not feel "tournament ready." Woods subsequently told friends, “I’m done”. On April 20, Woods announced that he had undergone his fourth back surgery since 2014 to alleviate back and leg pain. Recovery time required up to six months, meaning that Woods would spend the rest of the year without playing any professional golf. Woods returned to competitive golf at the Hero World Challenge in the Bahamas. He shot rounds of 69-68-75-68 and finished tied for 9th place. His world ranking went from 1,199th to 668th, which was the biggest jump in the world rankings in his career.
Masters Tournament: On Tuesday, April 15, two days after finishing second at the Masters, underwent arthroscopic surgery on his left knee in Park City, Utah, to repair cartilage damage. Expected to miss 4-6 weeks. It was the same knee operated on in 1994 for a benign tumor, followed by arthroscopic surgery in 2002. Began experiencing pain in mid-2007 when he injured his anterior cruciate ligament while running at home in Orlando following The Open Championship but opted not to have surgery at that time.
World Golf Championships-Accenture Match Play Championship: Captured second consecutive World Golf Championships-Accenture Match Play Championship for 40th career PGA TOUR win. With six match victories, including a 3-and-2 win over Davis Love III in the 36-hole finale, has won 12 consecutive matches, and overall Accenture Match Play Championship record is 20-3.
The foundation benefits from the annual Chevron World Challenge and AT&T National golf tournaments hosted by Woods. In October 2011, the foundation hosted the first Tiger Woods Invitational at Pebble Beach. Other annual fundraisers have included the concert events Block Party, last held in 2009 in Anaheim, and Tiger Jam, last held in 2011 in Las Vegas after a one-year hiatus.
Early in Woods' career, a small number of golf industry analysts expressed concern about his impact on the competitiveness of the game and the public appeal of professional golf. Sportswriter Bill Lyon of Knight Ridder asked in a column, "Isn't Tiger Woods actually bad for golf?" (though Lyon ultimately concluded that he was not). At first, some pundits feared that Woods would drive the spirit of competition out of the game of golf by making existing courses obsolete and relegating opponents to simply competing for second place each week.
