“Carlos has been amazing,” Manuel said. “If he’s swinging it well, he seems to come up at the right time and put a good swing on it.”  The Mets could not do much against Milwaukee starter Ben Sheets, who shut them out for five innings before leaving with tightness in his left groin muscle. Ryan Braun doubled in a run in the first, right after J. J. Hardy tripled off left fielder Daniel Murphy’s glove. Santana, who allowed two runs and seven hits with 10 strikeouts, balked in a run in the sixth.  But for the third time in six games on this trip, the Mets came from behind to win.  “Good teams do this,” Delgado said. “We’ve been grinding it out, we’ve been fighting. Ideally, you want to be ahead, but you’ve got to be ahead. But if you’re not, you’ve got to continue to put together good at-bats, get base runners and try to get a big hit.”  Beltrán led off the seventh with a double, and scored on a wild pitch by Mitch Stetter. Murphy led off the eighth by doubling on a 3-2 pitch from Gagné, the once-dominant Los Angeles Dodgers closer whose earned run average rose to 6.81 with his sixth blown save of the season.  David Wright, who struck out in the sixth with runners at the corners, struck out in the eighth with no outs and Murphy on second. Gagné threw two quick fastballs for strikes to Delgado, who struggled to see the ball in the afternoon shadows at Miller Park. He lofted the next fastball into the first row of seats in right field.  “I was just trying to make contact,” Delgado said. “They’re probably the worst shadows I’ve ever been involved in in professional baseball, but it goes the same way for both teams.”  But could the bullpen hold the lead? In Sunday’s 6-2 victory at Florida, Manuel needed five relievers to secure the final nine outs. On Monday morning, he joked about all those trips to the mound.  “I’ve got to get a new pair of tennis shoes; I wore these out,” he said, sneaking a quick look beneath his desk for effect.  Figueroa retired the side in order in the seventh. But when Braun doubled to lead off the eighth, Manuel summoned the left-handed Feliciano, who struck out Prince Fielder. On came Joe Smith to face the right-handed-hitting Corey Hart and the former Met Mike Cameron. Smith struck them out. Then it was Ayala, who was unavailable the last two days in Florida with a groin-muscle strain. This time, he retired the side in order in the ninth.  “They attacked the hitters, threw strikes, and the catchers did a good job bringing them to that,” Manuel said. “I felt going in, a lot of our right-handers appeared to match up well against this team. They’re a very aggressive-hitting club.”  Manuel did not use Aaron Heilman, who walked in the winning run Saturday at Florida and also worked a third of an inning Sunday. Delgado said he was just glad the lead held up, something that has not always happened, especially in Santana’s starts.  “It was nice,” Delgado said. “It was nice to see Figueroa come in and get some quick outs. And Ayala, a nice 1-2-3 inning. That’s great.”  DAMION EASLEY started at second base for the second consecutive day. Jerry Manuel said he thought LUIS CASTILLO was “wincing almost with his back and leg” after playing Friday and Saturday on Florida’s hard grass surface. Castillo pinch-hit in the ninth and struck out.  A version of this article appears in print on , on Page D1 of the New York edition with the headline: Delgado Hits No. 462, And Bullpen Helps Again.
