Vinny Mitchell and Billy Joe Saunders both protected their unbeaten records as they punched out points successes over durable opposition on the undercard at Frank Warren's show at York Hall on Friday night.

Mitchell, like Saunders is trained by father-and-son duo Jimmy and Mark Tibbs at East London's Ultrachem TKO gym, outpointed East Ham rival Johnny Greaves to record his eleventh straight pro win, while ex-Olympic boxer Saunders gained the verdict over rival Alex Spitko from Derby.

Greaves has survived against some talented rivals and took some of Mitchell's best blows without a shudder.

Mitchell was backed by his usual family following, including older brother Kevin, also unbeaten and a leading world super-featherweight title contender.

Mitchell attacked, throwing his usual pressure punches mixed with more controlled shots.

But Greaves was still upright at the final bell, although Mitchell had taken five of the six rounds on the scorecard of referee Ken Curtis.

After two wins earlier in the year, this victory was the 22-year-old prospect's second success in three weeks since moving gyms to train under the Tibbs partnership.

For middleweight Saunders, it was the first distance fight after three- inside-the-distance successes but strong rival Spitko lasted until the end of the four-rounder that closed the York Hall show.

The tough fighter showed his impressive variety of shots and shook Spitko more than once, but the determined Derby fighter shook them off and came back for more.

Saunders' fourth pro success was underlined with a 40-36 points margin from the third man Dave Parris.

There was another Friday night points winner trained at the TKO Gym. 'John' Wayne Hibbert made it three straight successes when he defeated tough Kevin McCauley on a points decision.

Tough McCauley traded solid shots in every round, but Hibbert was too strong and too aggressive as he chalked up a 40-36 victory on the scorecard of referee Dave Parris.
