The Dodgers landed Corey with the 18th overall choice, and McNamara said they got a good one.
"I've been around the family, and these guys are baseball players," said McNamara, who has seen Kyle go from a third-round pick to Seattle's starting third baseman. "Any person involved with the boys, you never hear anything negative. They play good, fundamental baseball and it's a credit to their parents. We congratulate Corey for being drafted. Kyle paved the way and we're proud of him."
The Dodgers still need to sign the 18-year-old shortstop, who has a commitment to attend the University of South Carolina, with a slot bonus of $1.95 million recommended.
Kyle, who also has a middle brother, Justin, playing ball at North Carolina-Charlotte, said the baseball genes were passed down by father Jeff, who played college ball at Fairleigh Dickinson University in New Jersey.
"He always instilled the work ethic in us," Kyle said. "He always took us out to hit, to take ground balls. He worked with all three of us all the time."
All three Seager boys also played high school basketball, "but Corey would always go to the cage and hit after basketball practice. He put in the hours."
