Broxton added to roster, Redmond optioned, Mesoraco to 7-day concussion DL, Navarro promoted, Costanzo designated for assignment.— Reds (@Reds) August 1, 2012
The 28-year-old Costanzo made his MLB debut this year with the Reds and got a cup of coffee with the team before ultimately being designated for assignment. The 6-foot-3 first baseman sported a brutal .056/.095/.056 in 17 games with the Reds. Though it was an extremely small sample, Costanzo had just 1 hit (a single) in 21 plate appearances while striking out 10 times to just 1 walk.
In related moves, the Reds placed catcher Devin Mesoraco on the 7-day concussion disabled list and called up catcher Dioner Navarro to take his place on the roster until Mesoraco is ready to return to action.
