At the start of today's slate of games, the average National League team had allowed 47 unearned runs over the course of the season.
The Phillies, on the other hand, had allowed just 19.
That number changed significantly today, when the Mets took advantage of a muffed double play ball in the first inning, scoring four unearned runs en route to a 7-4 victory at Citizens Bank Park.
The pivotal play came in the first inning, when Michael Martinez bobbled a ground ball by Ruben Tejeda, then was unable to make the throw to second in time for the force out. After a David Wright single loaded the bases, the Mets proceeded to score four runs: one on a groundout by Lucas Duda, and three more on a home run by Nick Evans.
