Swimmer Penny Oleksiak, the 16-year-old sister of Dallas Stars defenseman Jamie Oleksiak, won Canada's first two medals at the 2016 Rio Olympics.
Penny won silver in the women's 100-meter butterfly on Sunday after helping Canada win a bronze medal in the 4x100 meter relay Saturday as the anchor leg. The Toronto, Ontario, native set a Canada and world junior record with a time of 56.46 seconds in the butterfly.
Jamie, 23, was selected by the Stars with the No. 14 pick in the 2011 NHL Draft. He had trouble finding the words to describe the feeling of watching his sister win medals at the Olympics.
"I don't even know what to say right now, that was one of the most intense and amazing things I've seen," he wrote on Twitter on Sunday.
The Stars also tweeted their support for Penny.
Also competing at the games for Canada is women's basketball player Kia Nurse, the 20-year-old sister of Edmonton Oilers defenseman Darnell Nurse.
