The chances of Colorado ace Ubaldo Jimenez being dealt are now “around 50/50,” according to one major league source close to the talks.

For the moment, though, some of the suitors are dismayed at what they believe are high demands. An executive of one interested team described the current price tag as “unrealistic.” But that could change in the days leading up to Sunday’s 4 p.m. ET non-waiver deadline.

The Reds have been pursuing Jimenez for weeks, sources say, and they remain very much involved in the talks. The Tigers, who seem determined to add a starter, have Jimenez near the top of their list, as well.

Other teams who have at least checked in include the Yankees, Red Sox and Rangers, sources say. The Rangers, though, are focused primarily on adding a reliever.

An exchange of names has occurred between the Rockies and at least one team, a source said.
