What's not for sure is if that means the father is extra tough on his child or lets him slide by.
Angels second baseman Adam Kennedy has first-hand experience and knows exactly what playing for your father means.
"You're always hard to your son," Kennedy said. "You expect more, you expect a lot out of your children."
Kennedy was coached by his father, Tom, during his four years at J.W. North High School in Riverside, Calif., and said his dad always wanted more from him.
The second baseman, whose greatest moment as an Angel came when he hit three home runs against the Twins to help win Game 5 and the 2002 ALCS, credits his father with giving him the opportunity to learn and understand the game.
He said his greatest experiences of playing with his dad were in early elementary school, when Adam, along with neighborhood kids, would shag fly balls hit from Tom.
"Those are my fondest memories of what made me fall in love with the game," Kennedy said.
Kennedy said that while his father, who played baseball at UC Riverside, encouraged him to get better at the sport, he never forced it on him, and let Adam decide for himself to pursue a career on the diamond.
"He provided me with the info and that lifestyle. He definitely didn't push it on me at all," Kennedy said. "I love it and I made the choice."
Tom Kennedy, along with his wife Susan, come from Riverside to nearly every Angels home game to watch his son, who he trained his entire childhood, take the field.
