Instead, the team told him to go to Triple-A to build up arm strength, he explained to reporters in Port St. Lucie.
Feliciano said he will consider opting out and signing with a different team because he feels he is ready to pitch in the big leagues right now, Newsday's Marc Carig said on Twitter.
"I have to talk to my agent first and then see what we're going to decide," he said, according to ESPN New York.
Update - 5:24 pm: Terry Collins said the main reason Feliciano is being kept off the roster is because of his stamina - his shoulder is not yet strong enough to pitch on consecutive days (Rubin, ESPN New York).
In other words, congratulations, Robert Carson, since Terry Collins said he wants to have two left-handed relievers in his bullpen. Basically, the Mets have a roster crunch coming, and this was a gamble that Feliciano will not find (or opt to look) for a new home, meaning it's one less person the team must cut to make room for Marlon Byrd, LaTroy Hawkins, etc., who need to be added to the 40-man roster.
Feliciano is coming off shoulder surgery, he looked so-so this spring with a low-80's fastball, while pitching a portion of March wearing a heart monitor. I bet he rolls craps on the open market and ends up with the Mets in Las Vegas... and eventually in Queens some time this summer.
