Maver's title bid down to the wire.
Maver Newman Scott lead the way with eight points, followed by Browning Quaker with nine and Daiwa Cleveland with 10.
There are four sections on the Bowesfield section of the Tees, which has been hit and miss this season, so much will depend on whether anglers are pegged on the bream shoals.
The river is likely to have a steady flow, so the match should be a fair one with most pegs capable of producing fish.
The lower Tees fished reasonably well for last weekend's match, with several species feeding and several anglers in with a shout of the honours.
In the end local rod Paul Healey of Yarm lifted the Simpson Cup - by a single ounce.
He weighed in 13lb 3oz to pip Geoff Douglas of Daiwa Cleveland Angling Centre, who thought he was on the way to victory, but missed out by the narrowest of margins, finishing with 13lb 2oz.
Healey had three bream with skimmers, on feeder and worm from peg 190 in a match fished by 24 anglers.
Douglas, on peg 170, below the paddock field, was one small fish short of victory.
He tempted three bream, two of them small, a nice perch of over a pound, and roach, again including good fish pushing the pound mark.
Feeder and red worm was his chosen method, and anglers were mainly pleased to have a match that was not dominated by bream.
Bream tend to switch on and off at this time of year, so they can't be relied upon as much as in other seasons, though they will feed steadily in mild spells.
The perch, by contrast tend to become more active in the winter months, and can be voracious feeders.
The trick for all anglers - as long as they are pegged on fish - is to make the very most of the spells when the fish are feeding, and get as many in the net as possible, for they can suddenly switch off.
Derek Reeney of Maver Newman Scott made double figures for third place.
He took 10lb 14oz to the scales. THORNABY AA's next match is tomorrow week, for the President's Cup.
Pleasure anglers on the upstream reaches towards Croft, Hurworth and Coniscliffe, can expect dace, chub and grayling to make up nets, with feeder and float both effective methods.
Small worms, and maggots will be favoured baits, and with leaves in the water becoming less of an issue, bait presentation should be easier than for the last few weeks.
