.Marnus Labuschagne completed his county season at Glamorgan with a record-breaking bowling efficiency during the course of Friday's T20 Blast suit against Somerset in Cardiff.The Queensland leg-spinner claimed career-best designs of 5-11 from 2.3 overs, featuring a triple-wicket maiden, to help spin Somerset for 123 in 13.3 overs at Sophia Gardens.It was actually the greatest bowling efficiency through a Glamorgan player in the T20 layout, improving Graham Wagg's 5-15 versus Worcestershire in June 2013. Brought into the strike in the tenth over, Labuschagne removed rivalrous leader Lewis Gregory prior to tidying up Somerset's tail, with his four continuing to be dismissals each bowled.Gregory's shift stimulated a frenzied crash of 7-35, with Glamorgan travelling in the direction of a commanding 123-run victory.Watch every ball of the England v West Indies examination set LIVE & special to Fox Cricket, available on Kayo.
