BOSTON -- David Ortiz presents two very distinct faces to the world, and before the game, the Big Papi smile shone through the steady rain as he was feted in the first of three pregame ceremonies built in his honor this weekend. About 20 kids who have benefited from his work with hospitals lined up on the field, arranged from shortest to tallest, and Ortiz grinned as he greeted each of them with a handshake, and when that was over, Ortiz approached a security guard assigned to stand in front of the Red Sox dugout -- a familiar face -- and slapped him on the shoulder and chatted jovially.
