Wallstedt stopped 22 of 24 shots in Wednesday's 2-0 preseason loss to the Stars.
Wallstedt was tasked with his first start of the preseason, but the team in front of him was largely an AHL-level roster. In that context, this was a good performance for Wallstedt, who will also play in Minnesota's preseason finale at home versus the Stars on Friday. The 23-year-old netminder will carry a heavy load in goal to begin 2026-27 while Filip Gustavsson (hip) misses the first month-plus of the campaign.
