Alexander Ovechkin agreed to a $124 million, 13-year contract extension Thursday with the Washington Capitals, working out the details himself in negotiations with owner Ted Leonsis and general manager George McPhee. The Capitals scheduled a news conference for 8:30 p.m. to officially announce the deal. The 22-year-old Russian star was in the final season of a three-year, entry-level deal. His salary-cap number for this season, taking into account bonuses, is $3.83 million. If he had become a free agent at the end of the season, the Capitals would have had the right to match any offer from another team. Leonsis long maintained he intended to make sure Ovechkin remained with the Capitals.
