DeSmith turned aside 23 of 26 shots faced during Thursday's 3-2 road loss to the Capitals.
DeSmith gets tagged with the Stars' first loss of the season. The 33-year-old will fall to 1-1-0 after logging a shutout in his first appearance and isn't likely to see a regular workload as long as Jake Oettinger -- who signed an eight-year, $66 million extension Thursday -- is healthy and productive.
