The Mets are in need of another rally. This time from the bats, not the arms.

Already counting on a patchwork starting rotation to fill in for the injured Johan Santana and Chris Young, the lineup will need to pick up production to replace David Wright. The Mets’ third baseman has a stress fracture in his lower back and if a second opinion confirms the original diagnosis, he will need to rest at least 10 days, general manager Sandy Alderson said before last night’s late game with Florida.

“His presence in this lineup is something we need,” manager Terry Collins said. “We’re going to ask other guys to pick it up. I was shocked and unhappy.”

The team believes the injury occurred when Wright collided with Carlos Lee in a 6-1 home loss to Houston on April 19.

In the 23 games following, Wright went 15-for-83 with four homers, nine RBIs and 11 runs scored. He is hitting just .226 with six homers on the season.

“This has been downplayed on his part,” Alderson said of Wright. “He’s not the kind of guy who likes to come out of the lineup, much less potentially go on the disabled list.”
