Ireland coasted to a 6-0 win over China to progress to the quarter-finals of the World League tournament in Antwerp.
Alan Sothern hit a hat-trick with Peter Caruth, Ronan Gormley and Stephen Dowds also scoring in the Pool B game.
A Sothern brace and Caruth's strike had the Irish 3-0 up at half time before goalkeeper David Harte was later stretchered off with a neck injury.
Ireland face Belgium in their final Pool game on Sunday but are already guaranteed a quarter-final spot.
A top-three finish in the tournament would guarantee Ireland a place at the 2016 Olympics, while finishing fourth or fifth would also provide a strong chance of reaching Rio.
The first quarter on Friday saw few chances before Alan Sothern scored twice in quick succession in the second quarter, with a quick strike and a reverse strike.
Sothern was again in the midst of the action and won a penalty stroke when he was fouled during a penalty corner, but the shot was saved.
Caruth scored the third goal after terrific link-up play between Watt and Jackson set up a tap-in.
David Harte was forced to make a stunning save two minutes into the second half but was later stretchered off after a collision with a Chinese striker.
Gormley added Ireland's fourth goal before Sothern completed his hat-trick a minute later.
Stephen Dowds added the final goal and both teams were reduced to nine players during a fiery fourth quarter.
Ireland: Harte, Jackson, Gormley, Watt, Cargo, Sothern, O'Donoghue, Darling, Good, Gleghorne, Harte.
Subs: Bell, Dowds, Maggee, Caruth, Shimmins, Fitzgerald.
