The play Mauricio Dubon made in the sixth inning was overshadowed by the one he made in the fifth, but as Dubon talked of his swipe tag that wiped away what looked to be a surefire stolen base, it became clear why the Giants have fallen in love with their rookie infielder. Kevin Kramer tried to take second on Jeff Samardzija and Buster Posey and got a good jump. The pitch was up and in, leaving Posey little time to make a throw, and his effort veered toward right field.
