Yoenis Cespedes was the power presence the Mets needed when they added him for the stretch run last season, and he led them all the way to the World Series. With every game this season having added importance for New York in the National League Wild Card hunt, Cespedes delivered with a go-ahead two-run home run in the top of the seventh inning in a 5-3 win over the Reds on Tuesday at Great American Ball Park.
