Washington's Nationals took a 3-1 lead into the eighth inning tonight, but struggling left-handed reliever Felipe Rivero had a disastrous outing, giving up three hits and two walks (one intentional) and ultimately six runs, five earned as the San Diego Padres rallied for a 7-3 win. The loss snapped the Nationals' four-game win streak and left them 43-26 overall on the year with one more to play in Petco Park tomorrow afternoon. Gio Gonzalez vs Drew Pomeranz at 4:10 PM.
