Chicago Cubs closer Carlos Marmol will most likely be pitching for another team before Opening Day.

Several teams, including the Detroit Tigers, are taking a hard look at the reliever, according to league sources, with the regular season just three weeks away. Detroit is going with 22-year-old rookie Bruce Rondon as their closer, replacing Jose Valverde who left as a free agent.

Marmol will earn close to $10 million this season and can opt for free agency in November. Marmol can veto a deal to four West Coast clubs, but a source said Marmol would most likely waive that clause knowing he would be traded to a contender.

Although the Cubs have no pressure on them to move Marmol, it appears they would not hesitate to deal him for young pitching. They signed closer Kyuji Fujikawa, who saved 220 games in Japan, to a two-year contract during the winter, and he would step in as the Cubs closer if Marmol is traded.
