“It was a fantastic achievement for the club and reward for the riders after all the bad luck we have had this year,” said Trigger.
“It was nip and tuck all the way through and, bearing in mind the problems we have experienced, I had my thumbs crossed during the final race until Brady Kurtz crossed the finishing line in first place.
“That is the first major silverware we have achieved with the Devils. Our best performance in the Premier League before that was to reach the play-offs last season. Now we have a trophy to show for our efforts and that will always be in the record books.
“It is just a shame there is no home meeting this Friday to enable us to celebrate a brilliant achievement. We will have to wait to parade the trophy in front of our supporters.
“Hopefully, it will prove to be a timely boost and the confidence will take us through the rest of the season, meaning people will want to come and support us.”
Although Plymouth do not have a home fixture this week, because of lack of medical cover, the Devils will be in Premier League action at Ipswich on Thursday evening.
Trigger has called up two former Ipswich riders as guest replacements because Plymouth will be without three regular team members.
Rohan Tungate takes over at number one because Brady Kurtz is on World Team Cup duty with Australia and Leigh Lanham comes in at reserve in place of injured Stefan Nielsen.
Sam Simota is also out because has aggravated an injury he received at Berwick at the beginning of July and the Devils will operate rider replacement to cover his absence.
Ipswich: Danny King, James Sarjeant, Nico Covatti, Morten Risager, Ben Barker. Reserves: Joe Jacobs, Danyon Hume.
Plymouth: Rohan Tungate, rider replacement for Sam Simota, Kyle Newman, Todd Kurtz, Jack Holder. Reserves: Leigh Lanham, Ellis Perks.
