Minnesota and California plowed through the Greco-Roman competition Wednesday at USA Wrestling's Junior Duals in Tulsa, while Illinois and Oklahoma walked a tightrope to the same destination. 

At the end of the tournament's opening day, those four teams won their respective pools and secured a spot in Thursday's Gold/Silver pool, along with Washington, Florida, Wisconsin and Iowa. 

Minnesota tore through Pool A with three lopsided wins, beating Kansas Red (68-2), Tennessee (48-17) and Washington (56-12) while racking up 39 wins in 45 individual bouts. 

California was nearly as dominant in Pool C, posting blowout victories against South Carolina (67-3), Kansas Blue (41-23) and Wisconsin (44-17). 

Illinois, aiming for its fifth straight Junior Greco title, nearly got knocked off in the Pool B final. Florida collected two pins, a disqualification victory and four technical superiority victories to force a 33-33 tie that tipped in Illinois' favor on criteria, thanks to its eight match victories in 15 bouts. 

The Pool D final went down to the wire as well before Oklahoma edged Iowa 34-32 when A.J. Heeg held off Tate Naaktgeboren 7-5 in a battle of Big 12-bound 182-pounders.
