It was a disappointing loss for the Eels who were coming off a big win over the Roosters in the previous round.
Parramatta had the perfect start when they opened the scoring after just three minutes. But they didn�t see the Cowboys� in-goal again as the home side went from strength-to-strength, to lead 14-6 at half time.
The Cowboys went further ahead in the second half, locking out the Eels in the process.
The match went beyond doubt in the 65th minute when Cowboys five-eighth Nathan Fien ducked through to set up Rod Jensen who scored next to the uprights.

FULL TIME: A polished performance from the Cowboys. The longer the game went on, the more dominating the Cowboys became, posting their 7th victory of the season. The Cowboys win coming on the back of some tremendous defence with Luke O'Donnell and Steve Southern topping the Cowboys tackle count. Every one of the forwards worthy of mention thus giving half back David Myles and five eighth Nathan Fien room to set up their outside men.
For the Eels, they were impressive last week against the Roosters but have crashed tonight. They copped the raw end of the stick from the penalty count but by-and-large, they lacked discipline. It would take a diehard supporter to think they are a chance for the top eight.
