Between the raindrops, the Phillies rode the clutch hitting of Reid Brignac and John Mayberry Jr. to a 7-3 win over the San Diego Padres on Thursday afternoon. For the first time in more than three weeks, the Phils have won three games in a row. Now comes the difficult part. Or at least something that has proven to be very difficult for the Phillies. Can they win four in a row? Good teams do it frequently, but the Phillies haven’t been a good team in quite some time. To wit: They have not won more than three games in a row in over a year -- since June 2-6, 2013, when they won five in a row, to be exact. A team with a payroll of more than $180 million that hasn’t strung together a four-game winning streak in over a year? Hard to believe, Harry. “I didn’t know that,” said Mayberry, who got the start at first base in place of resting Ryan Howard on Thursday and smacked a three-run home run in the seventh inning to help key the three-game sweep of the Padres. “It’s hard to believe.” Winning pitcher Kyle Kendrick echoed Mayberry.
