Way up in the reserve seating level at Dodger Stadium, thousands of Boston Red Sox fans screamed, hugged and danced with just as much fervor as the World Series-winning players on the field below. Amid the gleeful chaos, a father in a Red Sox T-shirt and a Bruins cap held aloft his screaming 5-week-old daughter in the chilly Sunday night air, baptizing her in the sights and sounds of another Boston sports championship. The Red Sox had just capped one of the greatest seasons in baseball history with a 5-1 win and a five-game Series victory over the Los Angeles Dodgers.
