Clarke notched three power-play assists in Monday's 8-7 overtime loss to the Senators.
The two teams combined for seven goals with the man advantage, and Clarke had a hand in all three of the Kings' power-play tallies to record his first points of the season. The 21-year-old blueliner worked on the top power-play unit Monday, and his big performance could allow him to hang onto that plum assignment as long as Drew Doughty (ankle) remains sidelined. Jordan Spence is Clarke's main competition for time with the man advantage.
