Renowned sportscaster Bob Costas wore dark glasses as he talked cheerfully in that famous voice about his passion for baseball.

“I just like the game in different settings. In my mind, football doesn’t really start until the World Series is over. Not everyone feels the same. It’s subjective,” he said.

Costas attended the Charleston RiverDogs game on Saturday night at Riley Park. He came here with his son, Keith Costas, a producer for MLB Network. They planned to return to New York on Sunday.

Costas said it was his first visit to Riley Park, which he said reminded him of Camden Yards, home of the Baltimore Orioles.

“It’s nice,” he said.

He mentioned his longtime friendship with RiverDogs partner Gene Budig, who accompanied Costas as he sat in for an inning with the team play-by-play announcer Sean Houston.

“That was definitely a surreal experience. I was extremely nervous,” Houston said.

Costas was on the air here chatting with Houston during the bottom of the seventh inning and the top of the eighth inning. Houston said afterwards that it had already been an unusual year for the RiverDogs with Alex Rodriguez of the Yankees playing two games in rehab with the team. “Not your typical minor league season,” Houston said.

Costas, a sportscaster for NBC since the early 1980s, has been a prime-time host of a record nine Olympic games. He also does play-by-play for the MLB Network as well as hosting “Studio 42 with Bob Costas,” an interview show.

He was among 3,912 in attendance at the game, which the RiverDogs lost to the Rome Braves, 8-5.

“I like minor league baseball. This is just a lover of baseball tour,” Costas said.
