On June 12, 2016, Kessel won the Stanley Cup after defeating the San Jose Sharks in six games. Kessel played on a line with Nick Bonino and Carl Hagelin that was the most effective line for the Penguins in the playoffs (called the HBK line). Kessel led the Penguins in playoff scoring with 10 goals and 22 points and also led the team in shots with 98. Kessel narrowly missed winning the Conn Smythe Trophy as playoff MVP, falling short of teammate and captain Sidney Crosby by three points. In the 5-3-1 point distribution scheme based on the ballots of 18 voters, Crosby had nine first-place votes, five second-place votes, and three third-place votes, while Kessel had seven first-place votes, eight second-place votes, and one third-place vote.
