Mesoraco is out of the lineup Monday against the Rockies.
Mesoraco started the previous two games for the Reds after returning from a leg injury, but he'll take the day off to give his leg some more rest. The 27-year-old managed to get a hit in both of those starts, but he has gotten off to a dreadful start at the plate, batting a mere .143. Tucker Barnhart will start behind the plate and bat seventh in his place.
