Middleweight seems to suit Roberto Soldic just fine.
The former Konfrontacja Sztuk Walki welterweight title holder moved up to 185 pounds in the KSW 56 main event, where he scored a first-round stoppage of former divisional champion Michal Materla (29-8). The fight became a one-man show after Soldic (18-3) caught Materla with a left hand and dropped his opponent one minute into the round. Soldic punished his opponent with a few follow-up punches, but "Magic" somehow survived Soldic's first assault.
Sensing that Materla was still rocked from those shots, "Robocop" kept his opponent guessing with several punches and kicks. In a desperate attempt to make the barrage of punches stop, Materla went for a takedown, which Soldic blocked with ease. The end of the contest arrived after "Robocop" poured another battery of shots on his Polish opponent. The referee jumped in to stop the action at the 4:40 mark of the first round.
In the co-main event, Tomasz Narkun (18-3) successfully defended his light heavyweight championship against Ivan Erslan (9-1). The Croatian challenger gave the defending champion a hard time in the first round, making "Giraffe" miss and then countering with effective combinations of his own. Since Erslan arguably took home the first round, Narkun had some urgency as he entered into the second stanza. A well-placed punch from the defending champion turned the odds in his favor. After dropping his opponent on the canvas, "Giraffe" jumped on, took the challenger's back, and sunk in a rear-naked choke. Erslan couldn't resist the pressure for long and tapped out 51 seconds into the round.
In a 125-pound affair, Justyna Haba (3-1) took home a unanimous decision victory after outpointing Karolina Owczarz (3-1). Immediately prior, Bellator MMA and Strikeforce veteran Marius Zaromskis (23-9) overcame Andrzej Grzebyk (17-4) after Grzebyk injured himself at the 4:58 mark of the first stanza.
Elsewhere, Mateusz Legierski (7-0) earned a hard-fought majority decision in a 160-pound catchweight against Francisco Albano Barrio (7-2); Filip Pejic (15-4-2) rendered Sebastian Rajewski (9-6) unconscious with the very first right punch he landed 11 seconds into their 150-pound catchweight clash; in a razor-close featherweight affair, Daniel Torres (11-4) edged Max Coga (22-7-1) via split decision and Robert Ruchala (4-0) forced Michal Domin (3-2) to tap to an armbar with one second remaining in the first stanza of their featherweight clash.
