Tiger Woods plays a practice round Tuesday at Augusta National as he tries to win a fifth Masters starting Thursday. (Photo: Jack Gruber, USA TODAY) AUGUSTA, Ga. — There's just something about Tiger this year. The look is different, the swagger is back. The joy is evident, the smiles more frequent. And with club in hand, he is reminiscent of the Tiger who dominated the sport for a decade. MICKELSON: Another bold move for Lefty? Just three years removed from a public scandal that shattered his home life, tarnished his impeccable image and wrecked his play on the golf course, Tiger Woods is in a better place these days at one of his favorite places in the world. KEY GROUPINGS: Woods to play with Piercy, Donald Having rebuilt his swing under relentless analysis and sharpened his putting stroke after a tip from a friend, the red shirt on Sundays means something again. He will be the prohibitive favorite when the Masters begins Thursday. This towering presence who has won six times in his last 20 starts on the PGA Tour — including his past two — is again No. 1 in the world. "He's so happy," said fellow golf pro Steve Stricker, who gave Woods a putting lesson a month ago and joined Woods for a practice round Sunday at Augusta National. "He's smiling, he's joking around. He's in a good mood. He seems a little more at peace with himself. "He must have things in order." THE MASTERS: No one forgets his first time Outside of the ropes, it appears he does. After a single-car accident outside his former home in Florida in November 2009 — a crash that led to revelations of serial infidelity and ultimately cost him his marriage and millions of dollars in endorsements — Woods has slowly rebuilt his life one day at a time and his game one swing at a time. Further removed from his divorce in 2010, he seems happy as he and Olympic ski champion Lindsey Vonn announced via Facebook and Twitter last month that the two are dating. He is sharing custody of his two children, daughter Sam, 5, and son Charlie, 4. And he is as healthy as he has been in years, his surgically reconstructed left knee and aggravating Achilles injuries posing no threat, which allows him to fully train and practice.

A happy Tiger is a dangerous Tiger at Augusta National
Tiger Woods has won 77 times on the PGA Tour, five short of the all-time record held by Sam Snead. Here, on June 15, 2008, Woods makes a birdie on the 18th green to force an 18-hole playoff with Rocco Mediate at the U.S. Open at Torrey Pines. Woods won that playoff the next day for his 65th victory and 14th major. Now, take a look back at all 77 of Woods' victories. Gary A. Vasquez, USA TODAY Sports
