Yes, it's correct. You could also say "Mary sneaked . . ."
As you can see in this dictionary entry, both sneaked and snuck are correct forms of the past tense.

Boy! How's that for letting slang take over??!! I guess we can expect "drug" to become a new past tense form for "drag"!!
I checked my 30-year-old Webster's Third New International Dictionary (Unabridged) and it states that "snuck" is dialectical.
This is a great example of our ever-changing language.
