Kim Heiduk led home the Grenadiers in eighth place on a punchy fourth stage at the Tour de Wallonie.
Heiduk sprinted to eighth place after a late breakaway saw him finish in the chasing bunch on the 163km stage.
Brandon Rivera and Heiduk were active throughout the race, both attempting to make breaks but none of which were able to stick.
Artem Shmidt recovered quickly from a puncture to regain control of the peloton, storming on the front to catch the two early breakaway riders with 20km remaining.
With six kilometres to go, a stinging attack by Mathias Vacek (Lidl-Trek) saw him escape off the front with three others, and eventually take the win seven seconds ahead of Heiduk.
The German rider now sits in ninth place on the GC with one stage to go.
