Mesoraco is not in the lineup for Friday's game against the Giants, C. Trent Rosecrans of the Cincinnati Enquirer reports.
Mesoraco is off to a slow start since returning from the DL, going 6-for-27 with one home run. On a positive note, he has held up to catching back-to-back games and should continue to see the lion's share of the playing time behind the plate for Cincinnati.
