The Seattle Mariners have been operating with just six relievers this week, something Lloyd McClendon acknowledges can't continue much longer.

"I think we're close (to making a move)," he said. "I don't think it's (Thursday). It may not even be the next day, but I think we're close."

Dominic Leone appears to be the leading candidate for a promotion to the Major League club.

Part of the reason why Seattle has gone with a short-handed bullpen is that adding someone might require them to designate one of the veteran non-pitching reserves for assignment.
