Daniel Murphy’s switch to the leadoff spot yesterday was supposed to create more opportunities for David Wright. But why pass the baton when you can finish the job?

With the Mets needing a run for the lead in the eighth inning, Murphy came to the rescue with a monstrous home run against Kyuji Fujikawa that led a 4-3 victory over the Cubs at Wrigley Field.

In one of their most impressive victories of the season, the Mets rallied from a 3-1 deficit in the seventh on rookie Juan Lagares’ first major league homer, a two-run blast against Travis Wood. An inning later, Murphy hit his fourth homer of the season, putting the Mets ahead.

“It’s one of the probably bigger home runs that I’ve ever hit,” Murphy said. “Just because it was a tie ballgame and it was really nice to put a good swing on the ball and get us the lead right there. It was a fun game to be a part of.”

Greg Burke, Scott Rice and Bobby Parnell combined to hold the Cubs scoreless over the final four innings after Dillon Gee struggled. The rookie Rice was the most impressive of the group, with two perfect innings. The Mets (17-24) won two of three against the Cubs for their first series victory since April 19-21, when they swept the Nationals.

Lagares brought the Mets alive in the seventh with his two-run blast against Wood that made it 3-3. To that point the Mets had only four hits and appeared on the verge of getting dominated by a starting pitcher for the second straight day, after Scott Feldman rolled to a victory on Saturday.
