Kundratek skated for the Czech Republic in the 2009 World Junior U-20 championship and had six assists (tops amongst Czech defensemen) in six games though the team did not reach the medal round.
2009-10: Kundratek was one of three Medicine Hat defensemen with 30 or more points in his second WHL season as the Tigers finished third in the Central Divison. In 65 regular season games he scored 2 goals with 33 assists and was +13 with 63 PMs. Kundratek skated in all 12 playoff games and was +3 with 1 goal, 5 assists, and 23 PMs. His only playoff goal was scored on the power play.
2010-11: Kundratek moved into pro hockey as a 20-year old, skating for the Rangers' AHL affiliate Connecticut. In 70 games he scored 2 goals with 10 assists and was an even plus/minus with 42 PMs. The Whale finished third in the Atlantic Division and Kundratek played in all six games in the Whale's first round playoff loss to Portland.

2011-12: Kundratek made his NHL debut – appearing in five January games with the Capitals – after being obtained by Washington in a trade with the Rangers in October 2011. He was an even plus-minus with no points and 2 penalty minutes; averaging 9:45 minutes of ice time with the Caps. He began the season with New York AHL affiliate Connecticut; skating in seven games and finishing minus-one with 2 assists and 2 penalty minutes prior to the trade. Kundratek played 55 games with Caps' affiliate Hershey, scoring 12 goals with 11 assists, and was plus-three with 34 penalty minutes. Hershey reached the playoffs after finishing third in the East Division. Kundratek played in 4 of 5 games in the Bears' series with Scranton/Wilkes-Barre and was minus-three with 4 assists and 4 penalty minutes.
Kundratek is a solid defensive defenseman, who is a good puck mover with a nice shot. He has good height, but still needs to fill out and get stronger.
