Carruthers put up an admirable display to win the William Hill West Wales National at Ffos Las in the hands of 7lb claiming amateur Nico de Boinville.
The 2011 Hennessy hero (6-1) dug deep on the run-in at the end of three and a half gruelling miles to hold Cannington Brook by two and a quarter lengths, with another 32 lengths to the third horse Alfie Spinner.
Mark Bradstock's stable star, a course winner on Boxing Day, shared pacemaking duties with Shaking Hands until the latter cried enough and after that there was only Cannington Brook standing between Carruthers and glory. And try as Cannington Brook might, he could not get past the gallant winner.
De Boinville said: "He's a complete superstar to ride. He's a privilege to ride and he teaches me. He came up out of my hands a couple of times and he just loves it.
"I wondered if we were going to get home as we went a good gallop, but he kept on pulling out more. He heard the other horse coming and he just found that extra. He's a horse with real heart."
There was a sting in the tail as De Boinville was banned for two days for using his whip above the permitted level.
Ffos Las owner Dai Walters saw his colours carried to victory when the highly promising Top Gamble (2-1) took the William Hill Download The App Novices' Hurdle.
The David Pipe-trained five-year-old put up a tremendous front-running performance on his jumps debut in the hands of Conor O'Farrell as he followed up a course bumper success by six lengths from Sidney Melbourne.
O'Farrell said: "He was very novicey at his hurdles. He's going to be a chaser in time and the hurdles are a bit small, but he just kept galloping and he's ground them into submission. He was a bit green in front and jumping slow. I wanted to make it a test of stamina, and my lad was never going to stop."
Heath Hunter (2-1 favourite) gave Pipe a double when partnered by 7lb claimer Tom Bellamy to take the Walters UK Standard Open National Hunt Flat Race.
