Marlins owner Jeffrey Loria promised further activity Wednesday at the GM meetings, saying, "Stay tuned."
But in all likelihood, the Marlins probably have made their biggest moves - trading second baseman Dan Uggla and reaching agreement with free-agent catcher John Buck.
The team, according to one major league source, has about $3 million to $4 million left to spend.
Such a figure wouldn't be enough for the team to sign a free-agent starting pitcher such as right-hander Carl Pavano.
However, it could be enough for the Marlins to continue supplementing their bullpen. The team has traded for four relievers in the past week.
"We're always looking for pitching," Loria said. "We want this bullpen to be a tough one. We're still not done there."
