Fiala scored two power-play goals in Monday's 8-7 overtime loss to the Senators.
The 28-year-old winger beat Anton Forsberg midway through the first period to open the scoring, then snapped a shot past Mads Sogaard late in the second after Ottawa had switched goalies, giving Los Angeles a 5-4 lead that didn't hold up. The goals were the first of the season for Fiala. who has three points through three games as he looks to record 70-plus points for the fourth straight campaign.
