MESA, Ariz. -- Carlos Marmol doesn't pay attention to the trade rumors that seem to include the Cubs' closer every other day.
Marmol was mentioned recently as possibly drawing interest from the Tigers, who are looking for a closer. He has given Cubs management a list of five teams he would approve a deal to, but said he has not been approached about it.
"I don't worry about that," Marmol said Friday. "I just keep working here."
The rumors may continue all spring.
"I can't make that decision," Marmol said. "The boss guy makes the decision. I can't worry about that. The only thing I have to worry about is being ready every time they give me the ball."
Does Marmol think he'll be traded this year?
"I don't believe anything," the right-hander said. "I come here, work out and whatever decision they make here, I don't have anything to do with it."
What's been encouraging is that he is ahead of last season, as far as Cubs manager Dale Sveum is concerned.
"Last spring, we were still in that fistfight trying to get him to throw that fastball more, to get something out of Spring Training," Sveum said.
On Thursday, Marmol failed to finish one inning because he reached his pitch count for the day.
"That's all right," he said about his outing, in which he walked two against the White Sox. "I felt very good. I liked the way I threw the ball yesterday. The ball was coming out of my hand good, my body feels great, everything's good.
"I don't worry about walks, especially here," he said. "I'm trying to work on my pitches."
