Sandy Alderson concluded his introductory press conference less than an hour ago at Citi Field and made a positive first impression in laying out the groundwork for the first year of his four-year contract with the Mets.

Among the topics he addressed:

FRONT OFFICE: As suggested here yesterday, Alderson said a priority would be in piecing together his staff. He stressed the word “collaborative,’’ meaning he’ll bring in some quality people and delegate responsibility. It figures to be a staff that encourages the free flow of information and ideas, but Alderson didn’t leave any doubt that wasn’t afraid to pull the trigger on a decision. The farm system, he said, produced players last season, which could be interpreted as a plus for Terry Collins.

MANAGER: The impression is Alderson isn’t keen on bringing in a celebrity manager, which isn’t good news for those stumping for Bobby Valentine. Alderson did say he wasn’t averse to hiring a fiery personality, which leaves the door open to Wally Backman. The new manager should reflect the organization’s philosophy, and should have an intellectual and analytical side to him. Alderson mentioned no candidate by name, but speculation is Bob Melvin has emerged as a favorite. The interview process is expected to begin next week.

THE FUTURE: Alderson said he’s not focused beyond 2011. He admitted he doesn’t expect to be a big player in this winter’s free agent market, but that the Mets expect to be players in the future. Alderson acknowledged the team has financial constraints with up to $130 million earmarked in salary for next season. He also said the team should be competitive in 2011, and with increased production from Jason Bay and others (Carlos Beltran for one, but he didn’t mention him by name) the Mets could be better.

THE DEADWOOD: Alderson said: “I think we want to be thoughtful about everything we do. I’m mindful of public opinion, but I think we have to be circumspect here. I think we need to be careful about writing off any player or any asset we have without thinking about it carefully.’’ Alderson left the impression he would speak with Oliver Perez about 2010. Alderson didn’t say Perez had a role for next season, but he also didn’t say he didn’t, either. Unloading Perez in a deal will be next to impossible, so he’s not about to hurt himself in trade talks by trashing Perez now. Alderson is simply keeping his options open, which is the smart thing to do.

It was a good first impression, but considering where the Mets have been, it would’ve been hard for Alderson to not have impressed this afternoon.

I, like a lot of others, want Alderson to turn around this franchise. A competitive Mets team is good for the city and for baseball and today was a positive.
