Tiny Riverview Bible Baptist Christian School of Forsyth, Mo., posted one of the biggest upsets in the 63 year history of the Northeastern A&M High School Basketball Tournament Thursday.

The Eagles bumped off Oklahoma Class 3A No. 6 Tulsa Metro Christian 56-45 in a Boys' Gold bracket game at the Civic Center.

Twins Nathane and Teddy Simniok led the way for Riverside, scoring 19 and 17 points, respectively.

The Eagles led only 12-9 after the first quarter then rolled into the half with a 24-19 advantage. They inched away in the third period thanks to a 15-9 edge. Each team scored 17 points over the final eight minutes.

Joining the Simnioks in double figures for Riverview (which has a high school enrollment of 25) was freshman Alex English, who scored 11 points.

Metro, losing its second straight game to slip to 10-7, received 14 points from sophomore guard Danny Brown.

The Patriots tackle defending champ Roland tonight at 7:30 p.m. at the Civic Center. Riverview (16-1) meets Grove at 5 p.m.

Roland opened with a 53-45 win against Grove.

Other defending champs winning were the Walnut Grove, Ark., and Mannford boys and the Morrisville, Mo., Tulsa Edison and Fairland girls.

There were a pair of nailbiters Thursday, with Springfield (Mo.) Central getting a last-second shot to beat Enid 47-45 in the Girls' Blue bracket, and Blue Ridge (Mo.) Christian needed overtime to topple Oklahoma Bible Academy 48-40.

Another 34 games are on the schedule for today starting at 11:30 a.m. at the six venues - the NEO Student Activity Center, the Civic Center and gyms at Miami, Commerce and Fairland high schools and Will Rogers Middle School.

Eight of the 11 Lucky 7 Conference teams who played on Thursday posted wins.

In the Girls' Bronze bracket, Quapaw topped Tulsa Lincoln Christian 45-27 while Afton rolled to a 52-31 victory over Salina.

That means the two will be playing for the second time in three days and the third time this season. Afton claimed a 46-33 victory when the teams battled at Quapaw on Tuesday.

The Afton, Wyandotte, Welch and Commerce boys posted wins while the Welch girls joined Afton, Quapaw and Fairland as first-day victors.
