Keller scored a goal on six shots and added an assist in Saturday's 4-2 loss to the Senators.
Keller tied the game in the first period by converting his own rebound, then set up Barrett Hayton's third-period equalizer. The Utah captain has collected 13 points over his last nine appearances, notching two goals and 11 helpers over that stretch. He continues to provide a strong fantasy foundation despite the Mammoth's recent struggles.
