Donald Trump picked up 89 of New York's 95 delegates, putting him on a narrow path to clinch the nomination by the end of the primaries -- if he keeps winning.
John Kasich won four delegates and Ted Cruz was shut out.
The last two delegates will have to wait until the absentee votes are counted.
Trump has won 47 percent of the delegates awarded so far. He has to win 57 percent of the remaining delegates to clinch the nomination and avoid a contested convention.
Cruz and Kasich can only hope to block Trump, forcing a convention in which no one has a clear majority of the delegates.
The AP delegate count:
Needed to win: 1,237.
