Zak Chappell said he was impressed by the way the Outlaws responded to setbacks in the Vitality Blast with a resounding victory against Derbyshire at Trent Bridge.
The seamer was recalled from Gloucestershire for the fixture, and repaid the faith with a return of 3-28 off four overs.
His analysis proved too much for the visitors as they attempted a reply to 247 - a record score by the Outlaws, courtesy of half centuries from Ben Duckett and Alex Hales, and quickfire runs from Joe Clarke, Steven Mullaney and Tom Moores.
The 25-year-old admitted he had benefited from game time in Bristol where he has been on red and white ball loan, yet returned to an Outlaws squad still confident in their abilities.
