The Chicago Cubs told relief pitcher Carlos Marmol's agent that they expect to trade him sometime this summer, the Chicago-Sun Times reported Saturday.
While the team does not plan to deal the closer right away, it wants Marmol to build up trade value first. Marmol has reportedly given the Cubs a list of five teams to which he is willing to be dealt.
The 30-year-old will make $9.8 million this year, the final year of his contract.
Marmol said he is not concerned about the trade rumors.
"I don't worry about that," he said. "I just keep working here. I can't make the decision. The boss guy makes that decision. I can't worry about that. The only thing I have to worry about is to be ready every time they give me the ball."
Marmol saved 20 games last year and had a 3.42 ERA with 72 strikeouts and 45 walks in 55 1/3 inning.
