Twenty20 Cup, Leeds: Yorkshire 198-4 beat Durham 143-8 by 55 runs
Fleming broke a drought of outs for Yorkshire
Yorkshire failed by just two runs to become the first team to post 200 as they turned around their Roses defeat in style.
The Tykes, who were humbled by Lancashire on Thursday, set a new scoring yardstick for the competition with Stephen Fleming and Michael Lumb scoring swift half-centuries.
Fleming, whose form up to Friday had been horrid, clubbed 58 off 35 balls while Lumb's 50 used up just 31.
Yuvraj Singh (22 off nine balls) and Matthew Wood (37 not out off 28) also contributed to the onslaught, with Nick Phillips' 1-51 the worst return for Durham.
Durham's run-chase never got off the ground after Ryan Sidebottom reduced them to 15-3 early on.
Yuvraj also claimed three wickets, while Martin Love's 51 represented a lone resistance from Durham.
