In 55 AHL games with the Rampage he scored 4 goals with 13 assists and was +8 with 102 penalty minutes. San Antonio missed the AHL playoffs after finishing last in the South Division.
Petrovic is a gifted defenseman and an authoritative force in his own zone. Although he moves the puck well, it is the physical game where he excels. He punishes opponents in the corners and intimidates attacking forwards. He has added weight and muscle to his 6’4 frame, and he can get every ounce of his strength into his impressive slap shot. He skates well for his size, showing good maneuverability in all directions.
After a rookie season in the AHL and a brief six-game excursion into the NHL, Petrovic is close to being ready to make the leap to the big league, though he will probably spend another year in San Antonio. All but certain to become at least a middle-pair NHL defenseman, should Petrovic hit his full potential he could become a valuable two-way defender and a core player on the Florida blue line.
