MILWAUKEE (AP) – The Milwaukee Bucks have rewarded center Larry Sanders for his breakout season with a multiyear contract extension.   General manager John Hammond announced the deal Tuesday in a statement. Terms were not announced.   The 6-foot-11 Sanders had career-highs of 9.8 points and 9.5 rebounds last season. His 2.8 blocks per game ranked second in the NBA, and he had a stretch of 40 straight games with a block.  Hammond called the 24-year-old Sanders one of the top young defensive players in the league.  Sanders, the 15th overall pick in the 2010 NBA draft, is considered part of the core for the retooling Bucks, who traded Brandon Jennings to the Pistons last month for point guard Brandon Knight.
