Starling Marte’s 10th-inning, broken-bat single gave the New York Mets a 4-3 win over Philadelphia, a three-game sweep of the Phillies, an unbeaten homestand and a five-game NL East lead over their rival. The Mets have a seven-game winning streak and the best record in the major leagues at 18-7. Philadelphia has lost four straight. Last October, the Mets beat the Phillies in a four-game NL Division Series. The game featured a play at the plate, a balk that wasn’t, a 10th-inning, bases-loaded jam escape and an All-Star closer revealing one of his legs inexplicably was longer than the other.
