Colorado's Seymon Varlamov and the Blues' Jaroslav Halak produced a goaltending duel that seemed headed for a shootout before Jones delivered his unassisted goal. It was his second of the season.
Varlamov made 33 saves while Halak finally allowed a goal on the Kings' 20th shot.
Colorado has won two of its last three games, both of the victories having come in overtime.
