SISOWATH Knights broke out early and captured their second Cambodia Rugby Premiership victory of the season Sunday afternoon, beating Siem Reap 20-7 at Phnom Penh's Old Stadium.

Using their considerable size advantage in the forwards, the Knights jumped out to a 17-0 lead in the first 30 minutes of play and never looked back as they dominated a young Siem Reap side.

Flanker Yorn Vantha opened the scoring in the 11th minute as he grabbed a pass off a lineout and sprinted in for the try from 30 metres.

Sisowath then extended their lead to 10 points less than five minutes later, as No 8 Sam West dived in for the score off a penalty tap and go.

Sisowath continued to dominate, their front five pounding the Siem Reap defence with repeated hit ups. Sisowath prop Chro Kim Seang culminated the drive as he took a quick pass off a ruck at 10 metres out to score the try. West added the conversion kick to make it 17-0 Sisowath.

Siem Reap momentarily took back the momentum late in the half, taking advantage of a Sisowath penalty near the 22-metre line. Winger Nuon Leng took a pass off a scrum and sped in for the try. Siem Reap fullback Legris Benoit successfully converted, cutting the Sisowath lead to 10 before the interval.

The second act proved to be more of a defensive battle with neither team gaining the upper hand. West's 10-metre penalty kick in the 50th minute was the only score of the half to help Sisowath emerge 20-7 victors.

Sisowath coach Brian Thomas praised the play of his forwards, and in particular, the play of Chro Kim Seang.

"Seang was outstanding today," said Thomas. "He was a real leader out there, made some great tackles, and he ran hard."

Sisowath, whose record in the Premiership now stands at 2 wins, 3 losses, takes on Stade Khmer on March 8 at the Old Stadium. Siem Reap remain winless from four appearances.
