Kongsak Sitbonmee and Pakorn Sakyotin were the main winners at the Sor Sommai show at Rajadamnern Stadium. The main event was between Konssak and Petcheak Kiatyongut with Petcheak starting the stronger, almost putting the 2011 fighter of the year down for the count with a series of elbows and uppercuts in the second round.
Despite appearing on unsteady legs and suffering a cut from the elbow which started the onslaught Kongsak was able to recover and finish the round strongly. From that point on he was firmly in control, firing in body kicks from the southpaw stance and continually being the aggressor to take a comfortable decision win.
In the co-main event Konsak's old rival Pakorn, who will be fighting Saenchai Sor PK SaenchaiGym in Scotland later this year took on Monkonchai Petchsuphaphun. The first two rounds were uneventful but in round three Pakorn landed a perfectly timed elbow which put Monkonchai down for the count.
There was no way back for Monkonchai who lost his footing a couple of times in the fourth as Parkorn did a godo job of tying him up in the clinch and making him miss when he tried to press forward.
At the start of the night Prajanchay Por.Petnumtong won the vacant Rajadamnern flyweight title with a decision win over Methee Kiatpratoom while Kengsiam Nor Sriphung stopped Phudpadnoi Muangsima in the second round of their fight putting him down twice with a series of elbows and uppercuts, the second knock down forcing the referee to step in and stop the fight.
The next big show at Rajadamnern is on May 30th when Nong O Gaigandeao fights Petboonchu FA Group and F16 Rajanon rematches Yodtuontong Petchyindee.
