That's not a bad thing because his dad is Joe Castiglione, a longtime sportscaster and the play-by-play voice for the Red Sox.

Still, that moment, the one that hits all sons, happened when Duke and his wife were looking at vacation pictures.

"I'm standing like my dad," said Duke said of the shots. "I actually said to my wife, 'Look at my shoulders - I carry them the same way.'"

Duke and Joe won't be together Sunday for Father's Day because Duke will be covering the U.S. Open. For years, though, it was Joe who was away.

"The shoe's on the other foot," said Joe. "Now I'm the one home, and he's on the road."

When Duke was a kid, the extent of Father's Day celebrations depended on whether the Red Sox were home or away. It's like that in the life of a sportscaster - especially one who travels with a team. Missed birthdays and anniversaries are the norm, and calls replace being there.

Joe shares those experiences with his journalism students at Northeastern University to give them a taste of the downside. "Until you really experience being away, you don't understand it," he said.

He recalled when he worked a game in Detroit and Duke phoned the press box with the news that he hit a walkoff home run.

"That was a big thrill," Joe said, "but I did miss it."

The positives of the job far outweigh the negatives, Joe said.

Duke agreed, noting that Joe was always there to pitch batting practice or to watch the first couple of innings of his games before heading off to Fenway Park.

Growing up that way gave Duke a sense of the business and the people, along with an inside perspective most never get.

"I was mesmerized as a kid when I would see my dad on TV," Duke said. "I remember as far back, I was 4 or 5, watching my dad."

That was in Cleveland, where Joe worked weekends alongside Al Roker. The family moved to Boston in 1983, when Joe, a Yankees fan, began doing play-by-play for the Red Sox.

Duke got his start at a small station on Cape Cod, which led to a job in Springfield, Mass. He came to New York in 2000 to work at NY1, with help from WNBC/Ch. 4's soon-to-be-ex film critic Jeffrey Lyons, a mentor and family friend. He joined Ch. 5 in 2007 after stints at Ch. 2 and ESPN.

"I remember my late Uncle Charlie, early in Duke's career, said to me, 'He's better on TV than you ever were,'" said Joe. "And it's true. He's probably more relaxed. I just think he's more of a natural."

When the Red Sox are in town, Joe - who also has a son who is a doctor and a daughter who works in TV production - watches Duke on "Good Day New York."

"You always hope your children are better than you are," Joe said, "And I think in that sense, he is."

Duke, with his dad's shoulders, will get up Sunday, call his father and head to the U.S. Open.

"I guess, not to sound corny," Duke said, "every day is Father's Day."
