Voelker would lose a technical decision after accidentally poking Roger in the eye. He was able to defeat Cory Devela by decision two months later and was granted a rematch with Bowling. The pair headlined Strikeforce Challengers: Bowling vs. Voelker II in late 2010. This time, Bobby was able to dominate the fight and picked up a TKO win in the second round. Since they had split their first two fights, they were granted another rematch eight months later and again headlined, this time at Strikeforce Challengers: Voelker vs Bowling III.
