The Yankees need to get Johan Santana, according to catcher Jorge Posada. In a conference call to discuss the official signing of his four-year contract with the Yankees, the team's longtime catcher voiced his support for the Yankees' pursuit of the two-time Cy Young winner Santana, the hottest player on the trade market this baseball off-season. "We need a No. 1," Posada said. "We certainly need a No. 1, and I think that's the reason we're going after Santana." Posada stressed that the Yankees need an ace pitcher in the playoffs. The Yankees have not made it out of the first round in the last three years, partially because they have not had a dominant starting pitcher, such as the Red Sox's Josh Beckett this postseason. "It is a need in October, no question about it," Posada said. "I think when you look at the past World Series champions they were able to have a No. 1 throwing three games, or at least two games, to win the title."
