Watmough injury sours Sea Eagles' sixth straight win Manly 27 Warriors 12 Worrying signs: Anthony Watmough hobbles off injured for the Sea Eagles. Manly saw the return of one back-rower as they potentially farewelled another temporarily. Glenn Stewart was at his scheming best on a day the Sea Eagles lost Anthony Watmough to a knee injury. How serious Watmough's hyperextension of the knee is remains to be seen. The sight of him limping around the field at Bluetongue Stadium, having left the field only 29 minutes in, would have had some fearing worse. Can't touch this: Brett Stewart was instrumental for the Sea Eagles in their win over the Warriors. He didn't return for the rest of the match, which the Sea Eagles eventually won rather comfortably. Stewart has hardly been the 'gift' that keeps on giving this year, but he certainly was the pick against the Warriors, providing the final pass, kick or tip-on for the first four of Manly's tries, while having a hand in their fifth. Winger David Williams was the chief beneficiary of his good work, scoring a hat-trick. Brother Brett struck first and last for the Sea Eagles. The fullback's first, after 13 minutes, put the Sea Eagles on the front foot early, and they rarely looked as though they were going to be troubled from that point on. Halfback Daly Cherry-Evans's 40-20 had given the Sea Eagles an opportunity inside their opponents' quarter, and Glenn's ball to his brother Brett allowed them to take it quickly. But only two minutes later, Watmough was hurt. He rose and played the ball gingerly, limped a little, called the trainer, but then played on, and appeared to successfully run out his injury. The Sea Eagles, meanwhile, were pressing further ahead on the scoreboard. After 25 minutes, against the run of play, they scored through Williams. Again, Glenn Stewart was the man with the final pass, latching onto a Kevin Locke bat-back from a Shaun Johnson kick, galloping down field, before sending Williams on his way. Watmough went down again not long after that try. He struggled to get to his feet to play the ball, limped around again, tried to make a tackle, before finally leaving the field. It took the back-rower several minutes to get from the eastern side of the field across to the tunnel, on the western side. Meanwhile, the Sea Eagles began to limp a bit themselves. From a scrum, Warriors left-winger Manu Vatuvei loomed on the opposite side and gave right-winger Ngani Laumape a try eight minutes before the break. But Manly took control in the second. Glenn Stewart grubbered for Williams after 46 minutes, then batted the ball onto the winger after 57. The Warriors briefly responded, through Johnson, but Manly's strike-back was almost immediate, and fatal for the Warriors. Cherry-Evans wrapped around Glenn Stewart, before Brett Stewart scored his second. Sea Eagles skipper Jamie Lyon's 72nd-minute penalty goal put the match out of the reach of the Warriors, who have now lost their second straight match and the prospect of a finals position is looking slimmer. Manly, meanwhile, march on, having won six matches consecutively. They will be looking to flex their muscles against South Sydney at the same ground on Friday night. Their own premiership credentials, which could be tested by any absence of Watmough, are becoming stronger. They know how to win at this time of year, their desperation highlighted by centre Steve Matai's chase to deny Locke a try with three minutes remaining, when the result was already decided. Whether they can also chase down the likes of Sydney Roosters and the Rabbitohs in the race for the premiership remains to be seen. But we should all get a good idea on Friday night.
