Seattle began the third period on a two-minute power play after Ottawa forward Brianne Jenner was called for interference in the final second of the second. But Philips was up to the task, finishing with 25 saves.
Corinne Schroeder made 27 saves for Seattle (6-1-2-14), including one on a penalty shot by Jenner with 13:58 left to play.
Ottawa came in with a league-high 14 power-play goals but went 0-for-3 against Seattle. The Torrent came up empty on six tries with an extra skater.
Seattle activated Knight from long-term injured reserve before the game. Knight had three goals and seven assists in 14 games before sustaining an injury at the Winter Olympics.
The Charge beat the Torrent for a third straight time following a 4-1 loss in Seattle on Dec. 17.
Ottawa had been the only team without a regulation victory away from its primary home this season.
