First pair leaving yesterday somehow went wrong (7)

I believe the answer is:
strayed
'went wrong' is the definition.
(I've seen this before)
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for strayed that I've seen before include "Went wrong" , "Wandered away" , "Went off course" , "Went off the track" , "Dry seat (anag) - got lost" .)
