Down hurlers earned a deserved 1-22 to 1-13 win over London in the Christy Ring Cup quarter-final at Ballycran.
Danny Toner was among the Down scorers early on before a Gareth Johnson goal increased the home lead to 1-5 to 0-1.
The lead was increased to 1-14 to 1-4 at half-time as London netted a penalty after Conor Woods and Johnson had been among further Down point-scorers.
London reduced Down's lead to eight before they had John Hickey sent off as Down completed a nine-point victory.
In sunny conditions, Michael Johnston's side led throughout and formed a solid foundation in the first quarter.
Down were hugely in command early on and led by 1-07 to 0-01, following a Conor Woods pointed free after 18 minutes.
Playing with the aid of a stiff breeze in the opening 35 minutes, it was veteran player Johnson who netted the hosts only goal, in the 12th minute.
London staged a mini revival before the interval, with Clare native Bernard Gaffney netting a penalty goal, but Down were well on top and held that 10-point lead at the break.
The 62nd-minute dismissal of Hickey for the Exiles ended any lingering hopes they had of reducing their deficit.
Holders Kildare also joined the Mourne County, Kerry and Derry in the semi-final after they earned a 3-23 to 2-18 win over Meath at Trim on Saturday.
