Francisco Cervelli did, indeed, sign with the Braves today after being released by the Pirates.
What's more, he'll suit up tonight in New York for his new team's game against the Mets.
This was the official announcement:
The #Braves today signed C Francisco Cervelli to a major league contract and optioned C Alex Jackson to @GoStripers. In order to make room on the 40-man roster, the club transferred LHP Grant Dayton to the 60-day injured list. Cervelli will be active tonight and wear No.
