Source: Cubs in negotiations with Calero

The Cubs are currently engaged in negotiations with free agent

reliever Kiko Calero, one major-league source told

Calero is asking for a two-year deal, the source said. So

far, the team has resisted budging from a one-year offer.

The Cubs are wary of the history of injuries to

Calero’s right (throwing) shoulder. He was sidelined by a

torn rotator cuff in 2008, when he made only five big-league

appearances with Oakland. His 60 innings with Florida last year

were a career high, but he missed roughly three weeks with

inflammation in the shoulder.

Calero, 35, is an intriguing free agent after putting

together a very good 2009 season with the Marlins. He went 2-2 with

a 1.95 ERA in 67 appearances.

While the Cubs are committed to Carlos Marmol as their

closer, they have placed a high priority on adding a late-inning

reliever, sources have said.
