Miami Heat guard Tyler Herro has another baby on the way but apparently has no mercy for kids – at least not on the basketball court.

The former Kentucky star, who is headed into his fourth NBA season with the Heat, totally embarrassed a grade school kid during summer camp, putting him on skates and then breaking his ankles with a crossover.

Herro won the NBA’s Sixth Man of the Year award last season after averaging 20.7 points, 5.0 rebounds, and 4.0 assists for Miami, helping them finish first in the Eastern Conference.
