Grubauer turned aside 15 of 16 shots in Sunday's 4-2 preseason win over the Flames.
Grubauer played the first two periods of Sunday's game before giving way to Nikke Kokko in the third. The 34-year-old Grubauer posted relatively solid numbers in 2025-26 (2.65 GAA, .909 save percentage), but unless the Kraken take a step forward this year, wins may be difficult to come by for Grubauer.
