"We're awaiting," Reds manager Dusty Baker said. "We've got some tentative word, but I have to wait to hear from Walt [Jocketty] on what it is exactly."
Jocketty, Cincinnati's general manager, is not traveling with the club this week. Mesoraco started behind the plate while Mike Leake pitched Monday against the Phillies.
If the suspension is upheld before rosters are expanded on Sept. 1, there would be ramifications. The Reds would have to make a move to bring in a catcher while still playing with 24 men.
