Luke Metcalf's late penalty goal has sealed a 26-24 win for the Warriors that breaks both the Wests Tigers' hearts and their NRL winning streak. Eyeing their first three-game winning run in seven years, the three-time reigning wooden spooners shook off game-day injuries to Adam Doueihi (groin) and Samuela Fainu (knee) to take an unlikely six-point lead during Sunday's second half in rainy Campbelltown. But when Leka Halasima beat Jahream Bula and Jack Bird on a 70-metre tear down the right edge, the Warriors had levelled the scores as the final 10 minutes approached. The Tigers had been the more clinical side once in position and so would've liked their chances to land a killer blow, until their second-rower Alex Seyfarth hit Charnze Nicoll-Klokstad high with eight minutes to play. New Warriors halfback Metcalf stepped up and landed a penalty goal from 40 metres in front in greasy conditions, with Nicoll-Klokstad booed by the local crowd thereafter. The win is the Warriors' third on the bounce, leaving a horror round-one loss to Canberra in Las Vegas as a distant memory. The Tigers lost Doueihi in the warm-up and then Fainu during the first half, leaving them with an entirely second-choice left edge for the majority of the game after Jeral Skelton (hamstring) was ruled out duringthe week. But just as the Warriors looked ready to capitalise, star recruit Terrell May came up with his biggest play in a Tigers jersey yet to swing Sunday's contest back to the home side. Having scored with their first set after the break, the Warriors came within inches of going up by two tries when Bunty Afoa crashed over at close range early in the second half. May left all to continue wondering how the Sydney Roosters let him go when he held the big man up. Warriors half Metcalf passed the ball into touch on the next play and with the Tigers' next possession, they marched upfield to equalise. Lachie Galvin put boot to ball on a kick for back-up winger Solomona Faataape and, in the set after points, Latu Fainu strolled through Afoa and Leka Halasima to give the Tigers the lead. But Halasima's try on the back of a Taine Tuaupiki offload deflated the Tigers, who blew a late chance to steal victory when Faataape kicked the ball into touch working down the left. Tigers superstar Jarome Luai could face scrutiny for the match review committee for hitting Edward Kosi high early in the second half.
