The Yankees remain on the verge of acquiring Lance Berkman from the Astros as the slugger has waived his no-trade clause to allow a move, according to sources. The trade will likely be completed before Saturday's trade deadline. Houston will pick up $4 million of the $7 million owed to Berkman this year and in his 2011 option, sources said. New York will send two prospects to the Astros: reliever Mark Melancon and infielder Jimmy Paredes. Berkman vetoed a trade to the White Sox earlier Friday, USA Today reported.
