Lee Stempniak ended a 15-game goal drought with a first-period power-play goal for Blues, who have lost 11 in a row. St. Louis is 0-4 under new coach Andy Murray, although the Blues have earned points in consecutive games against Nashville after losing in a shootout on Saturday night.
Timonen's seventh goal, a slap shot from the high slot that beat Manny Legace, came with the Predators holding a 4-3 man-advantage. The Predators had been 0-for-10 before the goal, and the 11 power plays tied for the second-most in franchise history.
Dan Hamhuis's second goal of the season tied it for Nashville with 4:19 to go, ending Legace's bid for a shutout on the Predators' 27th shot. Nashville outshot the Blues 13-4 in the third period and 4-0 in overtime.
