Graham Thorpe made light of his England omission to lead Surrey's recovery on the first day at Guildford.
Middlesex elected to field and had the champions in trouble after dismissing openers Ian Ward (10) and Jonathan Batty (2) inside the first 10 overs.
But Thorpe joined Mark Ramprakash and they added 75 for the third wicket, taking Surrey to 95 for two at lunch.
