‘Saint’ clearly had the harder punches of the two, but had to come through a couple of scares to eventually see out a unanimous points decision.
Judges carded 118-110 across the board for Groves, who can move on to bigger things, although Murray showed once again he has a granite chin and balls of steel as he won the hearts of the London crowd.
In the only British title fight of the night, Chris Eubank Jr. kept a firm grip on the Lonsdale belt by dismantling Tom Doran in four rounds.
Eubank Jr. looked completely focused on the job in hand as he walked to the ring and proceeded to batter Doran into submission from the off. Two rounds of trading blows, with Eubank getting the better of it, were followed by a couple of one-sided sessions that saw Doran hit the canvas four times.
Referee Marcus McDonnell waved the fight off after the fourth knockdown and left Eubank to celebrate and potentially move on to a money spinning contest with Gennady Golovkin in September.
Dillian Whyte shook off the memory of defeat to Anthony Joshua with a sixth round knockout of Ivica Bacurin inside the same ring.
Whyte had too much power and ferociousness for the predominal cruiserweight, and despite swinging wildly at times, inevitably came out of top against the Croatian.
‘The Villain’ moves on to a date on the July 30 Leeds bill with a 17th career win and closer to a possible showdown with Dereck Chisora later this year.
