Parramatta hold off Gold Coast in crazy game at Robina
Parramatta halfback Mitchell Moses' right boot has secured the Eels a 26-20 win in a helter-skelter NRL contest against Gold Coast at Robina Stadium.
Moses picked up three try assists as the Eels held off a second-half fightback from the Titans to claim their fourth win of the season.
On the back of a Clint Gutherson double, the Eels were cruising with a 20-0 lead in the second half before Gold Coast twice deliberately conceded penalties to use their captain's challenge successfully to score.
Eels prop Junior Paulo was then controversially sent to the sin-bin for a shoulder charge on Titans' five-eighth AJ Brimson before a barnstorming solo effort by David Fifita got the hosts within four points.
Paulo was fairly noncommittal when asked after the game.
"I thought it was [harsh] too," Paulo told Fox Sports.
"I thought I hit him around the shoulder.
Gutherson, who had a stunning game at fullback, said it was "pretty tough" saying the contact was shoulder-on-shoulder."
Moses was less circumspect about the incident.
"He [Alex Brimson] went down with a shoulder injury, not even his head.
"When you run into Junior Paulo you feel it, your whole body feels it so I think he's going to be feeling it. I dunno about the call."
"It's a good tackle," Eels coach Brad Arthur said.
Despite the controversy, the Eels steadied when Moses struck back with his third try assist of the night off a kick for Dylan Brown.
Greg Marzhew's burrowing effort set up a frantic final five minutes as the Eels just held on to claim their second narrow win of the season over the Titans.
That finish looked far from likely after the Eels absolutely bossed the opening half, running in three unanswered tries and enjoying two-thirds of possession.
Gutherson opened the scoring in the 18th minute, moments after denying Brimson at the other end.
Parramatta then turned on the style for their second, some fast hands through the backline ending with Bailey Simonsson sliding into the corner.
The visitors' third try was not without controversy, with the bunker ruling Jarrod Wallace had spilt a Moses kick in the in-goal area despite the Titans' forward arguing he'd been taken out in the air.
Gutherson pounced on the loose ball to claim his second four-pointer with Moses converting to ensure a 14-0 advantage at the break.
Ryan Matterson extended the Eels' lead in the 46th minute but then the game swung dramatically in the hosts' favour.
Eels bemoan 'inconsistent' application of captains challenge
A clever piece of game management by Titans' halfback Toby Sexton finally allowed the hosts to get on the board in the 57th minute.
After a knock-on had been ruled against Jarrod Wallace, Sexton deliberately gave away a penalty to stop the play and allow a captain's challenge on the call, with the decision being overturned in the Titans' favour.
"It didn't go for us, so I'm not happy about it," Arthur said in his post-game interview.
Eels fullback Clint Gutherson said the rule seemed inconsistent.
"I remember watching a game last week and the ref said to the captain you can only challenge that last play for a penalty, not the play before," Gutherson said.
"I was just asking the question as I was watching the game last week, it seems pretty inconsistent.
From the resulting set, Phillip Sami won the race to a Brimson grubber to get the home team's first points.
The ploy having worked once, the Titans did it again with the same result in the 59th minute.
After Patrick Herbert was pulled back running in support for Jamayne Isaako, the Titans' centre deliberately interfered in the ruck to give away a penalty and call a captain's challenge for the interference.
The challenge was successful and from another Brimson grubber, Erin Clark was the beneficiary as the Titans cut the deficit to 10 points.
The game then ignited in the 63rd minute when Paulo crashed into Brimson, the bunker deeming the contact to be a shoulder charge and leading to the big Eel being placed on report and sent to the sin bin for 10 minutes.
Fifita took it upon himself to put the Titans within a try when he ran from dummy-half, crashed through Bryce Cartwright and then carried Gutherson over the line to score.
A conversion from the sideline by Sexton had the hosts within four points but Brown's four-pointer after Herbert failed to gather Moses' kick meant Marzhew's late try was in vain.

Latrell Mitchell injured in Rabbitohs victory over the Dragons
Latrell Mitchell scored a try after six minutes but left the field after quarter of an hour as South Sydney beat St George-Illawarra 24-12 at Homebush.
Already battling a knee injury, Mitchell lasted just 14 minutes before he limped from the field with a hamstring injury and did not return, with Blake Taaffe deputising at fullback.
The injury has already raised concerns over the Homebush surface, with Fox Sports reporting the Rabbitohs were unhappy with the turf.
Sections had to be returfed after a teenage music festival last week while the ground received 150mm of rain during the past nine days.
Souths have spent time without Mitchell in the past two years, with another hamstring injury ending his 2020 season early before reaching last year's grand final with when he was suspended.
They also lost to Brisbane in the opening round while he was still serving his ban.
The Rabbitohs have the lowly ranked Canterbury and Wests Tigers in the next fortnight, but any loss of Mitchell will still impact their attack.
Mitchell provided the finish to their best attacking play of the night on Saturday night before going off, opening the scoring after some enterprising ball movement.
Coming out of their own end, Jai Arrow and Campbell Graham both provided offloads in the lead up while Damien Cook also scooted downfield before Mitchell scored.
Cook was close to the Rabbitohs' best, running the ball seven times and totalling more than 110 metres.
He was involved in their second try as he darted out of dummy-half and helped Lachlan Ilias on his way before a quick play-the-ball allowed Keaon Koloamatangi to crash over.
Koloamatangi also had a role in another try, getting away an offload to help Taaffe get Graham over, while Ilias put on a ball for Taane Milne to hit a hole and score late.
The Bunnies were far from the complete package in just their second win of the season, with Cody Walker running the ball just twice and Souths completing at 58 per cent after the break.
The Dragons were often their own worst enemy.
They had more tackles in the attacking red-zone than the Rabbitohs in the first hour, but too often came up with errors close to the line.
Moses Mbye provided their highlight when he shoved off Koloamatangi to score early in the second half, while Jaydn Su'A also crossed in the last minute.
But ultimately their nine errors in 19 sets in the second half told the story of their night, with Zac Lomax also leaving the field late for a HIA.

'We can't keep losing': Ominous Melbourne Storm see off sorry Canberra Raiders in Wagga Wagga
Melbourne has comfortably beaten an error-strewn Canberra, 30-16, in Wagga Wagga, thanks to a classy performance from Harry Grant.
Jahrome Hughes scored twice as the Storm offered far too much for Canberra, who only had themselves to blame, with early penalties and ruck infringements along with handling errors haunting them as they suffered their third loss of 2022.
The Storm (4-1) looked superior in every aspect but their classy spine led the way, with superstars Grant, Hughes and Ryan Papenhuyzen scoring the first three tries of Saturday's game.
"[It's been a] really positive start [to the season]," Grant told Fox Sports after the game.
"You always want to start well and we're doing that.
Canberra looked intent on a sharp start and even led 2-0 early after a Brad Schneider penalty, but ball security and discipline issues quickly plagued them as the Storm took over.
"We can't keep losing," Elliott Whitehead told ABC Grandstand.
"It's gunna come together, but hopefully quicker rather than later."
Grant continued his hot form by bursting out of dummy-half and trampling Charnze Nicoll-Klokstad to score for a 6-2 lead after 15 minutes.
The Storm began to terrorise the Raiders' line and benefited from repeat sets, Hughes slicing through for a try before a Munster line break allowed Papenhuyzen to score his seventh try of the season, bringing his team to 18-2.
Semi Valemei finally got the Raiders first try by trucking through Papenhuyzen and diving for the line, his side left trailing 18-8 at half-time.
That fightback led to a typical Craig Bellamy spray at the break, which spurred the Storm back into action when centre Justin Olam broke through the Canberra line early in the second half to score.
Neither team would score again until the 72nd minute, when a sharp Nicoll-Klokstad pass found Nick Cotric to go over in the corner.
But playmaker Hughes snuffed any hope of a comeback with an outrageous 30m try, dancing around defenders and breaking multiple tackles to score under the sticks.
Grant impressed with a try, try assist, seven tackle breaks and 75 dummy-half run metres, with Cameron Munster also on fire with two try assists and more than 150 run metres.
The Raiders conceded three penalties in the game's first eight minutes, while errors continued to haunt them, with 14 for the game.
They now lead the league in most errors made across the first five games.
Canberra centre Matt Timoko left the game early with a leg injury.
