The Tory leader was strolling through a street festival in Toronto with his wife and daughter this weekend when he paused at a game stall.
Hudak, who had three-year-old Miller on his hip, first befriended two chatty little girls waiting their turn to play before offering to pay for their game.
After a couple of throws and much cheering from Hudak, all three children walked away from the booth with bright yellow ducks as prizes.
"High five, nice job," Hudak told his pint-sized new friends after the game. "We've got a future baseball player."
While introducing himself to parents with young children, Hudak also revealed his enthusiasm for a certain kids TV show.
"I love 'Yo GabbaGabba'," Hudak exclaimed to one parent. "It's a good show."
