The Cavaliers star guard and his longtime girlfriend, a 19-year-old Akron woman, had a baby boy Wednesday. No other details were available.

James left the team’s training camp in Columbus to be with her and his new son. He was expected to rejoin the team Thursday as he prepares for his second NBA season.

During the team’s media day Monday at Gund Arena, James wouldn’t comment when asked if he were about to become a father. He has always been guarded about his private life.

Fatherhood should fit James well. The reigning rookie of the year, who turns 20 in December, is most relaxed when he is among children. This summer, he donated money to refurbish basketball courts and youth community centers in Akron. He has also donated supplies to the city’s schools.

James was raised as an only child by his mother Gloria, who was estranged from James’ father when he was a youngster

“That’s my main goal, to try and be a better father than the one I had,” James told the Akron Beacon Journal. “I didn’t know him. I didn’t know the situation he was in. But I’m going to do my job the best way I can.”
