Delgado had left camp to be with his wife, who had an April 1 due date, in Puerto Rico. Carlos Antonio, named after both grandfathers, was born the following day.
"He looks like me, but a little lighter than me," Delgado said.
Delgado wasn't quite sure if his son was a left-handed or right-handed hitter. He was certain his life had changed.
"You don't sleep that well in the hospital, No. 1," he said. "And when we finally brought the baby back yesterday, he doesn't care. When he's hungry, he's hungry. And he cries.
"But it's totally worth it."
The experience tired him and took him away from his job.
"It's going to be a little rusty," Delgado said. "But what are you going to do? You can't be in two places at once. I said earlier I wasn't going to miss this for the world."
He was pleased to be back to baseball "but it was kind of hard to leave this morning," he said.
