The word "snagged" follows the spelling rule that when a one-syllable verb ends in a single consonant preceded by a single vowel, you double the final consonant before adding the suffix "-ed."
This happens because of the general rule concerning not only "-ed," but any suffix beginning with a vowel. The rule states that if the consonant ends either a stressed syllable or a single syllable word, AND the consonant is preceded by a single vowel the final consonant is doubled. Ex: "refer" becomes "referred," but "depart" remains "departed."
