The team said it agreed in principle to a new deal but did not disclose terms, the Los Angeles Times reported. General Manager Tony Reagins said the extension would ensure that Scioscia -- the longest-tenured manager in the American League -- "will be around for a long, long time."

Scioscia -- who is also the longest-tenured and most successful manager in Angels' franchise history -- is believed to earn $1.75 million a year under his current contract, which ran through 2009 with a club option for 2010, the Times said.

Under Scioscia, the Angels won their first World Series title in 2002 and have won the American League West title in four of the last five seasons. They reached the American League Championship Series in 2005, but fell to the Boston Red Sox in AL playoff series in 2004, 2007 and 2008.

The Angels have won 803 games and lost 655, a winning percentage of .551, since Scioscia took the helm in 2000.

"The job he's done in nine years here has been tremendous, not only at the major-league level but in his minor-league development philosophy," said Reagins. "This is an acknowledgment of the work he's put forth. You look around the game, and there are not many ahead of him."
