Former Orioles shortstop Mark Belanger was an early arrival at Camden Yards yesterday, listening in as his son stood near home plate rehearsing the national anthem. Robert Belanger, 28, of Lutherville, sang the anthem before last night's game, as he had done here four years earlier.
"He's the singer in the family," said the elder Belanger, a Major League Baseball Players Association official. "He didn't get it from me."
