McCann wasn't in the lineup for Friday night's series opener against the Mets. He wasn't even at Turner Field.
Instead, he was by his wife Ashley's side as they prepared for the arrival of their first child. Their son, Colt Michael, was born Friday afternoon.
"He's on paternity leave," said manager Fredi Gonzalez. "They induced her early in the morning. They're just doing the old 'hurry up and wait.' The good thing is that he's here."
Atlanta opened the second half with a weekend series against the Mets, then after an off-day, hosts San Francisco for three. But Ashley's due date was for next weekend, when the club was in Washington. they wouldn't return home until after their game on July 25.
McCann told Gonzalez at Thursday afternoon's workout that he wasn't going to take any chances on being out of town and having to rush back.
"This was planned," Gonzalez said. "During the All-Star Break, the doctor said, 'Let's get it done.' So he came in yesterday all excited. I can't blame him."
McCann is allowed up to three days for paternity leave according to the Collective Bargaining Agreement, but Gonzalez, who texted McCann on Friday morning, then "left him alone," said that he was under the impression that if all went well, his catcher would be back for Saturday afternoon's game.
With McCann on the paternity list, David Ross started behind the plate and hit seventh. The Braves called up catcher J.C. Boscan from Triple-A Gwinnett to fill McCann's spot.
