Swail could muster only one high break, a 67 in the fifth frame of the pair's best-of-nine clash, pocketing a 40 run in the next frame before Greene closed in on an upset.
"I played pretty well but Joe didn't play as well as he can," said Greene, who while Kent-born is also registered as a Northern Ireland player.
"The home crowd were on Joe's side. He had a few more supporters, but I didn't let it bother me. It's the perfect start for me."
