(SPEEDWAY 1)LAKESIDE have elected to track Stuart Robson as their doubling-up rider in the first leg of the Elite League play-off semi-final against Eastbourne on Monday.Robson shares a team place for the Purfleet club with Kauko Nieminen, and Hammers co-promoter Jon Cook admits it was difficult to choose between the pair.He said: "Neil (Vatcher) and I have had a bit to think about and we have come up with a plan to get the most out of the Rider Replacement facility on the night. It was a tough choice between Robbo and Kakke, and in the end it was Robbo's slightly better ability to come from the back that swung us his way."Kakke took the decision like a true pro and at this moment in time it's likely he will be in the second leg as his gating skills will be an advantage at Eastbourne."(SPEEDWAY 2)PLYMOUTH skipper Ben Barker led the way with a 15-point maximum as the Devils overcame high-flying Workington 47-42 at the St Boniface Arena.But promoter Mike Bowden has further problems to contend with as Justin Sedgmen has quit the club due to a loss of confidence - and Kyle Hughes' future also appears to be in doubt.Bowden said: "It was a very good team performance to come from behind to win, even though we effectively had a five-man team. In addition to using rider replacement for Sedgmen, Kyle Hughes had an off night and he says his confidence is shot to pieces."So we will be without Sedgmen and Hughes for our trip to Rye House on Sunday afternoon. We will bring in a guest for Sedgmen and use rider replacement for Hughes in the match at Hoddesdon."(SPEEDWAY 3)SCUNTHORPE promoter Rob Godfrey paid tribute to the team who worked to get the Scorpions' clash with Leicester on following heavy rain.The meeting was delayed for 80 minutes but did go ahead after water was cleared - with the home side losing their long unbeaten home record with a shock defeat against a Leicester side inspired by former Scorpion Magnus Karlsson, who scored a maximum.Godfrey said: "It just goes to show what can be done here after the rain stops. We owed it to a decent-sized crowd to try and get the meeting on and we managed it. Not only did we manage it but there was some great racing throughout."I'm just sorry the rain also took away our home advantage, making it ride like a slick track, and for the second time this season we've lost at home on a wet track. I'm pretty gutted to say the least, as on a grippy track we should beat anyone around here."(FIXTURES)SATURDAY SEPTEMBER 17:ELITE LEAGUE KO CUP S/F 2nd leg: Eastbourne v Poole 7.30PREMIER LEAGUE: Berwick v Rye House 7pm, Leicester v Somerset 7.30PREMIER LEAGUE KO CUP S/F 1st leg: Newport v Workington 7pmSUNDAY SEPTEMBER 18:PREMIER LEAGUE: Rye House v Plymouth 2pmPREMIER LEAGUE KO CUP S/F 1st leg: Glasgow v Newcastle 2.30PREMIER LEAGUE KO CUP S/F 2nd leg: Newcastle v Glasgow 8pm, Workington v Newport 7pmNATIONAL LEAGUE: Buxton v Isle of Wight 3pmMONDAY SEPTEMBER 19:ELITE LEAGUE PLAY-OFF SEMI-FINAL 1st leg: King's Lynn v Poole 7.30, Lakeside v Eastbourne 7.30GARY PETERSON MEMORIAL: Wolverhampton 7.30TUESDAY SEPTEMBER 20:NATIONAL LEAGUE: Isle of Wight v Sheffield 7.30CHALLENGE: Dudley v Birmingham Bulls 7.30WEDNESDAY SEPTEMBER 21:PREMIER LEAGUE: Somerset v Edinburgh 7.30
