Twenty20 Cup, Headingley: Yorkshire 186-5 (20 overs) beat Derbyshire 141 (18.1 overs) by 45 runs
Yorkshire made a winning start to county cricket's newest competition despite a first ball dismissal for new signing Stephen Fleming.
The New Zealand captain fell lbw to Dominic Cork in his debut appearance but the home side posted a daunting target, thanks to Michael Lumb and Yuvraj Singh.
Lumb hit three sixes in his 42 off 22 balls and Yuvraj made 44 before both fell to Michael Di Venuto, who picked up 3-19 in his four overs.
Richard Blakey added a final flourish to the innings and Derbyshire were soon in trouble in reply as Cork was run out for six and Ryan Sidebottom removed Nathan Dumelow and Mohammad Kaif.
Di Venuto was a class above his team-mates as he collected 11 boundaries in making 67 off 45 balls, but no-one else reached 20.
The Australian eventually holed out to long-on off spinner Andy Gray and the game ended with another run out as last man Luke Sutton perished, leaving Tom Lungley on 18 not out.
