Outside the bleachers of Fenway Park, Kate Wolman, 29, orders a sausage. Michael, the Sausage Man, gets on his knees and kisses her belly. Her husband, Dan, beams with joy. ''We celebrated after beating the Yankees," said Kate. ''We checked the timing with the doctors and we're pretty darn sure of it. We stayed up late. We watched all the replays and the rioting in Boston, and we decided to find a different way to celebrate. To avoid all the destruction."
