Carlos Delgado homered and drove in four runs Wednesday, getting New York’s offense rolling on a clear, cool night that was much more favorable to hitters, and the Mets’ rebuilt bullpen barely held on for a 9-7 victory over the Cincinnati Reds.

The Mets won the season opener 2-1 on a raw, 37-degree afternoon that showcased their offseason bullpen additions of closers J.J. Putz and Francisco Rodriguez. With temperatures in the 50s on a clear Wednesday evening, the offense took over and Rodriguez pitched out of a bases-loaded threat in the ninth to avoid a bullpen collapse.
