TUCSON, ARIZ. ? Nearly all of baseball’s general managers and a handful of agents are together this week, and still only one notable player has changed teams so far.

The Chicago Cubs beefed up their catching Wednesday, acquiring Damian Miller from Arizona for two minor leaguers.

But the lack of dealing isn’t from a lack of trying.

“We’ve talked to a lot of people this week. But 99 percent of what we talk about doesn’t lead to anything,” Diamondbacks GM Joe Garagiola Jr. said. “This one just happened to work out.”

Most of the work being done at the general managers’ meetings is setting the stage for the next two months.

Teams have started preliminary trade talks – finding out which opposing players are available and which of their own players are coveted. Agents and teams have also expressed interest to each other to hold more significant talks in the next few weeks, possibly at next month’s winter meetings.

But except for the Philadelphia Phillies, who made contract offers to free agents Jim Thome, Tom Glavine and David Bell on Tuesday, most teams are moving cautiously.

“It will be a slower-developing market, which is what we anticipated coming out here,” Mets general manager Steve Phillips said. “Teams have contracts they would like to trade to change their configuration.”

Arizona and Colorado have talked about swapping outfielder Larry Walker and third baseman Matt Williams. The Rockies are also exploring to see if there is any interest in overpaid pitchers Mike Hampton and Denny Neagle.

Florida, which hopes to unload Charles Johnson and Preston Wilson, could be interested in Hampton.

The Mets might be willing to take on Neagle as long as the Rockies take back one of New York’s undesirable players: Jeromy Burnitz, Rey Ordonez or Roger Cedeno.

Even the usually free-spending Yankees are looking to slash payroll. GM Brian Cashman is under orders to save money and is looking to deal Raul Mondesi, Rondell White and Sterling Hitchcock.

“I have a lot of ideas floating around,” Cashman said. “I’m just waiting for responses.”

The cost-cutting Braves have only offered Glavine a one-year deal, worth about $9 million. That could force the two-time Cy Young winner to leave Atlanta after 16 years.

Glavine was 18-11 with a 2.96 ERA this season and has 242 career wins.

“The chance today of Tom Glavine leaving Atlanta is a very real possibility,” said Gregg Clifton, Glavine’s agent. “Six months ago that wasn’t the case. But today, the chance that Tom Glavine will play with another team is a very viable possibility. It’s not just smoke.”

Clifton has also talked to the Yankees and Mets, while Texas has expressed interest in the pitcher.

Cashman has other decisions to make first, including whether to exercise Andy Pettitte’s $11.5 million option for next season by Friday.

For now, the Mets and Phillies are the most aggressive teams.

After a couple of weeks of talks, the Cubs and Diamondbacks were able to make a deal. Arizona sent Miller to Chicago for left-hander David Noyce and outfielder Gary Johnson.

Miller, 33, batted .249 with 22 doubles, 11 homers and 42 RBI in 101 games last season for the Diamondbacks, who won the NL West.

“He’s a good handler of pitchers and has done a good job for a long time,” Cub GM Jim Hendry said. “He was in the All-Star game last year and part of a world championship team and a strong contributor.”
