And the Irish with the corner kick, Dallas Moses with the kick, Reilly Harbach with the shot that goes just wide, scoreless.
Catholic with another opportunity later in that first half, the pass to Mitchell Moncada.
He can't get a clear shot because of Greenwood's keeper Evan Loyd, then Nick Hogan clears it out.
The Irish again, this time Moncada's pass right on the foot to Evan Craig but again Loyd is there to force the shot over the crossbar.
Catholic finally scored later, and the Irish go to 5-and-0 with a 4-nil victory.
