George Groves improved his unbeaten record to 15-0 as a pro fighter last night, as he came through a tough test against Mexican Francisco Sierra in San Jose, California.
The fight was stopped in the sixth round of the super-middleweight contest, Groves did the damage with an explosive combination of punches, a stunning right hook stopped Sierra advancing and the Londoner followed it up with a left to send his opponent crashing to the floor.
The South American did get up after his knockdown, but Groves took advantage of his dazed condition and quickly went back to work, forcing Sierra’s corner to throw in the towel.
It was another impressive performance from Groves, who had to work hard to remain undefeated against a tall, dangerous opponent who clearly possessed plenty of power himself.
Although wild and upright, Sierra, who boasted 22 knockout wins on his 32-fight record, did catch the English fighter with some heavy punches, including a body shot that briefly forced Groves to take a step back and steady himself.
The 24-year-old from Hammersmith was also hampered by a cut following a clash of heads in the third round and the doctor was asked to take a look at the gash between rounds, due to concerns over his visibility and blood loss.
Thankfully the flow of blood was treated by his corner, but the injury could put Groves' scheduled fight with Scotsman Kenny Anderson, a rematch of their 2010 clash on September 14, in doubt. Groves attended a hospital after the fight to receive stitches for his wound.
This entertaining bout was on the undercard of the Robert Guerrero-Selcuk Aydin fight at the HP Pavilion. In the main event Guerrero marked his move up to welterweight with a unanimous points win over German-based Turk Aydin, two judges giving 'The Ghost' the nod 116-112, with the other scoring it 117-111.
