The Marlins activated Baumann from the paternity list Friday, Christina De Nicola of MLB.com reports.
Baumann missed the series against the Twins earlier this week while welcoming a new addition to the family, but he will be back in the bullpen for the Marlins' final games of the season in Toronto. He has allowed 10 runs with a 17:4 K:BB over 12.1 innings during his time with Miami.
