He began 2012 in peak form, setting an indoor best of 46.85 seconds then winning his first national title at the Polish Indoor Athletics Championships. An appearance at the 2012 IAAF World Indoor Championships followed but the team faltered in the relay final and came in sixth (last) place. He achieved a season's best of 46.55 seconds outdoors, but did not compete internationally as a poor performance at the national championships meant he was excluded from the relay team that competed at the 2012 Olympics. He performances declined further in 2013, having only a seventh place finish nationally.
