Hofer turned aside 24 shots in Saturday's 5-4 win over the Red Wings.
Detroit grabbed a 4-2 lead early in the third period, but Hofer shut the door the rest of the way as the St. Louis offense launched a comeback. The 26-year-old netminder has a firm hold of the No. 1 job between the pipes for the Blues, going 6-3-1 in 10 starts to begin the season with a 2.42 GAA and .916 save percentage.
