Billy Wagner is staying with the Mets. A league source told FOX Sports that the reliever will use his no-trade clause rather than accept a deal to the Red Sox. Boston wouldn't meet both of Wagner's demands. He wanted assurance that they would decline his $8 million team option for 2010, which they provided. However, the Sox wouldn't guarantee that they would decline to offer Wagner salary arbitration, making him a free agent without draft-pick compensation. "It's not about the option or arbitration. It's about his desire to end the year healthy for the future," the source added. "He feels he has a better chance lasting a month in a less competitive environment than perhaps two months in a pennant race and playoffs."
