Saints took on front runners Sydney University in the round 13 do or die match at Hurstville Oval. With the Saints sitting three out of the top six, they need to win to stay in touch with only three rounds to play.
Originally a washed-out two-day game, Kurtis Patterson's addition and a win over Sydney Uni in the One Day Semi-Final a fortnight earlier had the team ready to take the early advantage.
Sydney Uni batted first and Saints opening bowler Peter Francis claimed early wickets to put the home team on the front foot.
No Uni batters got going and the introduction of spinners Moors, Engelbrecht and Graham combined to see Sydney Uni out in the 44th over for 153 runs.
"It was a brilliant combined bowling performance complimented by constant pressure from our fielders." Captain Nick Stapleton said
Sydney Uni didn't give up despite a determined 54 from the skipper, Stapleton, at the top of the order.
He combined with NSW batsman Kurtis Patterson (25 off 22 balls) for a handy 41 run partnership claiming the vital win.
The two clubs compete for an annual trophy known as the O'Sullivan O'Keeffe trophy named in honour of the Sydney Uni and St George cricket legends Michael O'Sullivan and Kerry O'Keeffe.
The two famous clubs have now shared the trophy four times apiece in its eight year history and the trophy was presented by Club President Kevin Greene to Stapleton.
St George are now in 7th position and will take on 5th placed Northern Districts in another do or die clash at Mark Taylor Oval in Waitara.
