By Matt Martell, The Associated Press SOUTH WILLIAMSPORT, Pa. — Lufkin, Texas, came from five runs down on Saturday to take the United States bracket at the Little League World Series. Its task may be even tougher on Sunday, when Lufkin takes on 10-time tournament winner Japan in the championship. Japan has won four of the last seven Little League World Series, and Tokyo Kitasuna, the club representing Japan this year, has won the championship three times before.
