Sion batted first at a picturesque Bready and despite losing Kevin Gallagher early they battened down the hatches and refused to be over-run by a full-strength Bready attack.
Skipper Ryan O'Neill played the innings of his life as he hit 11 fours in a knock of 78 that only ended in a frustrating run out and although the rest struggled a little, cameos from Andy Lucas (25) and Simon Galloway (20) allowed Sion to post a thoroughly respectable 184.
David Scanlon took the opportunity to give half of Tyrone a bowl, James Long with 3 for 25 and Agha Sabir did best of a long line with 3 wickets each.
The reply was pretty one-sided if the truth be told David Rankin dominating throughout as he smashed 12 fours and 7 sixes in an unbeaten 112.
The big opener has not so much been struggling this season as not building on good starts so this is bound to do his confidence the world of good.
Bryan Scanlon with 49 not out stayed with his team-mate in a thoroughly convincing start to their defence.
