LAKE BUENA VISTA, Fla. -- Celtics forward Gordon Hayward and his wife, Robyn, are parents for a fourth time.

Robyn Hayward announced the birth of the couple's first son -- Gordon Theodore Hayward -- on Wednesday, a couple of hours before the Celtics would face the Miami Heat in Game 4 of the Eastern Conference finals.

She said the baby -- who was already wearing Celtics apparel Wednesday with his father's name and number on the back -- will go by Theo, despite his father's preference that he go by GT.

"Our little man is finally here!" she wrote.

Gordon Hayward had originally planned to leave the bubble for the birth, but he remained with the Celtics. He got some unplanned time off earlier in Boston's postseason run because of a sprained ankle, and spent some of that with his wife and daughters before returning to the NBA campus.

"I think his ankle's fine right now," Celtics coach Brad Stevens said Wednesday after the birth was announced. "I don't think he's thought about it all afternoon obviously. ... Very, very happy to hear the news."
