Plymouth climbed to second place in the Conference League table, level on points with leaders Boston, thanks to their 58-34 win over Redcar at the St Boniface Arena on Friday evening.
It was another comfortable win for the powerful Devils side, although Redcar put up some spirited resistance, which produced some entertaining racing.
Even so, the visitors managed only two race wins, both by reserve Gary Beaton.
Nicki Glanz and Mark Simmonds were both unbeaten for Plymouth each from five races while Paul Starke dropped only one point to the opposition when he was headed home by Beaton in heat two.
Kyle Hughes was beaten only by Jade Mudgway and Devils skipper Seemond Stephens won his first three races before finishing last in his final outing.
Plymouth:
Mark Simmonds 14+1 (5 rides), Kyle Hughes 8+2 (4), Nicki Glanz 15 (5), Jamie White-Williams 2 (4), Seemond Stephens 9 (4). Res: Danny Stoneman 2+1 (4), Paul Starke 8+3 (4).
Redcar: Scott James 7 (4), Stephen Jones 3+2 (4), Aaron Summers (rider replacement), Jade Mudgway 10+1 (5), Benji Compton 4+1 (3). Res: Mike Mitchell 0 (3), Gary Beaton 7 (6), Richard Lawson (No 8) 3+1 (5).
Plymouth will be without three key riders Tom Brown, Nicki Glanz and Kyle Hughes for their trip to Rye House on Sunday (August 10) (2pm) for the second leg of the Conference Knock-Out Cup semi-final in which they will be defending a 57-36 lead from the first leg.
Brown is ruled out with a fractured thumb while Glanz and Hughes are on duty for their Premier League clubs.
The Devils operate rider replacement for Glanz, give an outing to 17-year-old Ben Reade, and make a late decision on the other vacancy.
Plymouth: Mark Simmonds, Ben Reade, Nicki Glanz (rider replacement), A N Other, Seemond Stephens. Res: Jamie White-Williams, Paul Starke.
