The Mets bullpen remains a work in progress, but one thing known for sure is it won’t include Pedro Feliciano — at least for now. The veteran reliever was informed by team brass yesterday he won’t be part of the 25-man roster for Opening Day, as the Mets prepare to head north with lefties Josh Edgin and Robert Carson in the bullpen. Feliciano, who last pitched in the big leagues in 2010, must now decide between accepting $100,000 and a minor league assignment or asking for his release. Feliciano said he will decide within the next few days. Feliciano’s velocity — which hovered in the 82-83 mph range for most of the spring — was a concern to the Mets, but manager Terry Collins said it was Feliciano’s inability to be effective in the second outings of back-to-back appearances that was the deciding factor. “His stuff wasn’t as crisp and he needs to be able to go out there and be sharp consecutive days in that role,” Collins said in Kissimmee after a 7-4 win over the Braves. Feliciano had a 2.08 ERA in eight appearances this spring and thought that might be enough. “I just thought to be here and throw strikes and get lefties out would open some eyes,” Feliciano said. “But they decided differently than I expected.” Collins hopes Feliciano will be back. “I think Pedro can help us,” Collins said. “I just hope he hangs on and spends a little time to get his shoulder in better condition. We’ve reached a stage where we thought we’d like to see him build up his shoulder strength.”
