Tiger Woods regains the No. 1 spot in world golf rankings with a win at the Arnold Palmer Invitational on Monday, March 25. Here, he plays a shot at the tournament in Orlando on Sunday, March 24. Check out what Woods has been up to since the last time he was the top-ranked golfer nearly 2½ years ago:
Woods appears dejected after losing to Lee Westwood and Luke Donald in the 2010 Ryder Cup competition in Wales in October 2010. That month, he lost his No. 1 ranking to Westwood, a position he had held for 281 consecutive weeks. He had taken a break from golf earlier that year after reports of marital infidelities emerged in late 2009.
Woods misses a putt at the Frys.com Open in October 2011. That month, he dropped out of golf's Top 50 players list for the first time in almost 15 years. Woods reportedly lost millions in endorsements after sponsors ended their ties with him in the wake of a sex scandal.
Woods misses the U.S. Open in July 2011, citing knee and Achilles tendon injuries. Here, he plays in the tournament in 2008.
Woods plays at the 2011 Emirates Australian Open in Sydney in November 2011. That year, he remained the highest-paid American athlete on Sports Illustrated's "Fortunate 50" list.
Woods drops his caddy of 12 years, Steve Williams, in July 2011. "I want to express my deepest gratitude to Stevie for all his help, but I think it's time for a change," Woods said. Here, the two share a laugh during a practice round two months before Williams was let go.
After a nearly three-month break, Woods returns to golf at the Bridgestone Invitational in August 2011.
Woods hits out of the bunker on the ninth hole during the first round of the PGA Championship in August 2011. He failed to make the cut at the PGA championship for the first time in his career.
Woods plays his tee shot on the 18th hole at the Presidents Cup in Melbourne, Australia, in November 2011. The previous month, Woods landed Rolex as a sponsor despite not having won a major tournament in nearly two years. "Rolex is convinced that Tiger Woods still has a long career ahead of him," the high-end watchmaker said.
Woods lines up his putt at the Honda Classic at PGA National in March 2012. He shot a 62, his lowest final round as a professional, at the Honda Classic, but he tied for second in the tournament.
Woods earns his first win since November 2009 at the Chevron World Challenge, a non-PGA tour event, in December 2011.
Woods signs autographs at the Arnold Palmer Invitational in March 2012. His win there marked his first PGA tour victory since September 2009.
Woods drops the ball on the 15th fairway during the final round of the AT&T National in July 2012. He overtook Jack Nicklaus for second place on the all-time PGA Tour list with his victory at the AT&T National.
Woods hits his tee shot on the 12th hole during the final round of the Farmers Insurance Open at Torrey Pines in January 2013. He lost his title the previous year as the world's top-paid athlete, dropping to third place on Sports Illustrated's "Fortunate 50" list.
Woods hits the ball on the 18th hole during the second round of the Deutsche Bank Championship at TPC Boston. He became the first PGA Tour participant to earn $100 million when he finished third and won more than $500,000 at the Deutsche Bank Championship.
Woods and champion skier Lindsey Vonn announced they were dating on Facebook in March 2013. Vonn recently divorced Thomas Vonn, who was also her coach, and Woods split up with his wife, Elin Nordegren, in 2010.
Woods tosses his ball to his caddie at the Farmers Insurance Open at Torrey Pines in January 2013. He started the new year in fine form by winning his 75th PGA Tour title in the Farmers Insurance Open.

STORY HIGHLIGHTS
- Woods returns to No. 1 spot after two-and-a-half-year absence
- Victory over Justin Rose takes Woods to joint record eighth win at same PGA event
- Woods now starts 624th week at the top of world rankings
(CNN) -- Nearly two-and-a-half years after losing the title, Tiger Woods reclaimed the world No. 1 golf ranking when winning the Arnold Palmer Invitational tournament on Monday.
The defending champion knew that only victory at Bay Hill would enable him to topple Northern Ireland's Rory McIlroy.
With thunder storms having pushed the final round of play in Florida into Monday, the 37-year-old defended the three-shot lead he held at the start of the day to finish 13 under par -- two ahead of second-placed Justin Rose.
Can winning really take care of everything in Tiger Woods' life?

"It has been a by-product of hard work, patience and getting back to winning golf tournaments," Woods said of regaining the coveted top spot.
As he tapped into the eighteenth, Woods became only the second golfer in history to win eight PGA titles at the same event -- joining the legendary Sam Snead, who achieved his tally at the Greater Greensboro Open (now called the Wyndham Championship).

German Martin Kaymer milks the moment as his putt on the 18th green ensures Europe will retain the Ryder Cup. His defeat of Steve Stricker capped an improbable comeback, as the Europeans triumphed 14½-13½ despite trailing 10-4 at one stage on Saturday.
Justin Rose punches the air as he caps an unlikely comeback of his own, defeating Phil Mickelson on the 18th green after being one down with two to play. The American described his loss as one of the turning points of the 2012 Ryder Cup.
Europe's victory echoed the 1999 Ryder Cup, where the U.S. also came from 10-6 down to win 14½ - 13½. The 'Battle of Brookline' was bathed in controversy as U.S. players stormed the 17th green in celebration at s crucial Justin Leonard putt. Golfing etiquette had been broken as Leonard's opponent, Jose Maria Olazabal, could still have squared their match.
Jean Van de Velde (middle) looks bewildered as he reflects on his defeat in the 1999 British Open. The Frenchman blew a three-shot lead on the final hole, so forcing a play-off with Justin Leonard (right) and Scotland's Paul Lawrie (left) which the latter won to seal his first major, despite trailing Van de Velde by an enormous 10 strokes before the final round took place.
Liverpool players celebrate with goalkeeper Jerzy Dudek (in black) after the English side completed their remarkable comeback against Italians AC Milan in the 2005 European Champions League final. Trailing 3-0 at half time, Liverpool scored three goals in six second half minutes in Istanbul to force extra time and a penalty shoot-out, which they won 3-2.
Players and fans of Manchester City celebrate after winning their first English title since 1968. City trailed Queens Park Rangers 2-1 but scored two stoppage time goals to win 3-2 - and so deny city rivals Manchester United the title. The success echoed United's 1999 Champions League triumph in Barcelona, where they beat Bayern Munich 2-1 despite trailing after 90 minutes.
Having won the last four gold medals, the Soviet Union were hot favourites to win ice hockey gold at the 1980 Winter Olympics. Few expected Team USA - made up of amateur and college players - to stop them but they defied the odds to beat the Soviets 4-3 in a semifinal which became known as 'The Miracle on Ice.' They went on to win gold against Finland in the final.
Despite being two sets and 5-1 down in his semifinal, Frenchman Henri Cochet managed to win the 1927 Wimbledon title. He stunned the world No. 1, American Bill TiIden, in the semis before repeating his escapology act in the final, trailing by two sets once more and surviving six match points before rallying to win in five sets for a third successive game.
It is the one-day cricket international that may never be equalled. Set a world record score of 435 to win in their allotted 50 overs, Graeme Smith's South Africa beat Australia in Johannesburg after racking up 438 runs, with just one wicket and one ball to spare.
It is baseball's greatest fairytale comeback. In August 2001, the Seattle Mariners were on their way to equalling the major league record of 116 victories in a season. They led the lowly Cleveland Indians 14-2 at the halfway stage and though the Indians rallied they still needed five full runs with only one out remaining - and got them to win 15-14 in the 11th innings, with Kenny Lofton grabbing the crucial score.

"I play well here -- and that's as simple as it gets," Woods replied when asked the secret of his success at Bay Hill.
While Snead needed 27 years to mark up those victories, Woods took just 13 -- nearly half the time -- to achieve the feat, having also managed to win three other tournaments on seven different occasions.
The American's form suggests he will be the man to beat at next month's Masters at Augusta, the first major of the year -- with many pundits awaiting his first major since 2008 to consider his comeback complete.
"That's up to them -- that's their opinion," said a relaxed Woods after his success. "I am very pleased with the way I am playing -- and that's enough for me."
Opinion: For Tiger, winning does take care of everything
The title, on one of his favorite courses, formally caps his return to the summit of golf -- which he spectacularly fell off when reports of numerous marital infidelities emerged in late 2009, whereupon he took an indefinite break from the sport.
The following August, his divorce from his Swedish wife of six years, former model Elin Nordegren, who is the mother of his two children, was finalized.
In October 2010, six months after returning to golf with such poor form that he failed to win a single event in a season for the first time since turning professional, Woods lost his world best crown to Englishman Lee Westwood -- ending a record run of 281 consecutive weeks at the top (which started in June 2005).
A combination of further poor form, added to injury, meant that a man who had once seemed invincible on the golf course dropped to a barely credible 58th place in November 2011.

But 29 months after losing his crown, Woods is back on top for the eleventh time in his career -- capping a fine month for both his game and private life, with the golfer having announced his relationship to skier Lindsey Vonn last week.
He will now start to add to the record 623 weeks he has spent on top of the golfing world, a tally which is nearly double that of his nearest rival, with Australian Greg Norman racking up 331 weeks, while no other player has broken the 100-week barrier.
The 2013 season may be in its infancy but the 14-time major winner has started in irrepressible form, winning three of his five tournaments -- after triumphing at Doral earlier this month and at Torrey Pines in January.
His 77th PGA Tour victory also marked his 99th professional tournament win as Woods, who has won the Masters on four occasions, prepares his bid to wear the famous green jacket for the first time since 2005.
