AUGUSTA, Ga. -- The possibility for the youngest winner in Masters history exists, as does the chance for the oldest major championship winner ever.

Throw in a guy trying for his second green jacket in three years, and another trying to win his country's first major championship, and a handful with the chance to join a recent trend of first-time major winners, and a compelling Sunday awaits at Augusta National.

Playing in his first Masters, 20-year-old Jordan Spieth shot a 2-under-par 70 on Saturday and is tied for the third-round lead with 2012 champion Bubba Watson at 5-under 211.

Matt Kuchar and Sweden's Jonas Blixt are another shot back, with 50-year-old Miguel Angel Jimenez and Rickie Fowler just two shots behind. Among that group, only Watson has won a major.

Spieth would become the youngest Masters winner, Blixt the first from Sweden to win a men's major, and Jimenez the oldest major champion dating to the first one in 1860.

Throw in Kuchar, who is in search of a first major, and Fowler, who is looking to live up to the hype. And then there's longtime European Tour rivals Lee Westwood and Thomas Bjorn another shot back, followed by 2003 U.S. Open champion Jim Furyk.

"There's a lot of players I think going to be in with a chance tomorrow," said reigning U.S. Open champion Justin Rose, who is 4 shots back.

Defending champion Adam Scott fell off the pace with a 76 that included a front-nine 40. He is six strokes back and in a tie for 16th.
