Jonas Siegenthaler

Jonas Siegenthaler (born May 6, 1997) is a Swiss professional ice hockey defenceman. He is currently playing with the Washington Capitals of the National Hockey League (NHL). Siegenthaler was rated as a top prospect, projected as a possible first round selection in the 2015 NHL Entry Draft, before he was selected 57th overall by the Capitals.

Playing career
Siegenthaler made his National League A debut playing with ZSC Lions during the 2013–14 NLA season. On 30 July 2015, Siegenthaler was signed to a three-year entry-level contract with the Washington Capitals. It was agreed that Siegenthaler would remain with the ZSC Lions to further develop on loan for the 2015–16 season. In 40 games with the Lions, Siegenthaler contributed 8 points from the blueline before suffering a first-round defeat in the post-season. On 16 March 2016, with the Lions season and his loan period at an end, he was reassigned to the Capitals AHL affiliate, the Hershey Bears.

He also spent the 2016–17 season with the ZSC Lions. After being knocked out with the Lions in the NLA quarter finals, he returned to the Hershey Bears in mid-March 2017.

The Capitals recalled Siegenthaler from Hershey on 8 November 2018, to play against the Columbus Blue Jackets the next night at home in his first NHL game. Veteran Capitals defencemen Brooks Orpik (injured reserve) and John Carlson (day-to-day) were both unavailable to play. Siegenthaler scored his first NHL point on 14 December 2018 in a 6–5 win over the Carolina Hurricanes, gaining the primary assist on a goal by Alexander Ovechkin.

Personal life
Siegenthaler's father is from Switzerland, while his mother is from Thailand. He is the first known NHL player of Thai descent.

International play
Siegenthaler competed with Team Switzerland at the 2013, 2014 and 2015 IIHF World U18 Championships. His outstanding play was recognized when he was named to the 2015 U18 WJC All-Star Team. He was also selected to participate at the 2014 Ivan Hlinka Memorial Tournament.

He was chosen to skate, as a 17-year-old, with the Swiss U20 squad at the 2015 World Junior Ice Hockey Championship.

Siegenthaler played his last WJC for Switzerland in 2017 where he tallied 6 points (1 goal and 5 assists) in 5 games and was Switzerland's most used player with over 25 minutes of ice-time per game.
