General manager Sandy Alderson did not want to say much as he walked down a Citi Field corridor with his dog after the Mets' season ended Sunday night -- but what little he said made it clear how frustrated he was.

"We're going home disappointed," he said. "To me, it wasn't a successful season if it wasn't as successful as we all would have liked. We didn't play really well."

Alderson was most upset by the Mets' lack of offense in a 7-2, 12-inning loss to the Royals in Game 5 of the World Series on Sunday night.

"We had three hits tonight," he said disgustedly, undercounting the actual total by one. "We can talk about the glovework, we can talk about baserunning and we can talk about defense -- none of those things that we do particularly well.

"But the bottom line is we didn't hit. And we had two ninth-inning leads and one eighth-inning lead [in three of the Mets' four losses] . . . That's the way it goes."

Asked about manager Terry Collins' decision to let pitcher Matt Harvey start the ninth inning, Alderson said: "I don't really want to talk about tonight's game tonight. It's not fair."
