A gender reveal took the field at Camden Yards during the Baltimore Orioles’ game against the Athletics on Sunday afternoon.

Orioles pitcher Anthony Nunez gave Baltimore one inning of work and helped keep the team’s 2-1 lead in their eventual win. As he walked off the field, he mouthed to the camera, “It’s a boy.”

It was an apparent message to his brother and sister-in-law.

“Anthony is mouthing ‘it’s a boy’ for some family members,” MASN broadcaster Kevin Brown said. “His brother and sister-in-law, Danny and Makayla Delgado, are expecting child No. 3. And that, folks, is one of the most creative gender reveals you’ll ever see. Anthony had the answer. Danny and Makayla did not know, and I hope that you two are watching.”

Nunez explained that his family was together for Mother’s Day and that his brother was hoping to surprise them.
