FARGO, N.D. - All four returning Junior National Greco-Roman champions kept their hopes alive to repeat titles Monday at the ASICS/Vaughan Junior Nationals.

Returning champs Marty Eng of Oregon (112 pounds), Shawn Jones of Idaho (125) and Jesse Robbins of Florida (171) each remained unbeaten entering the final day of the Junior competition.

Returning champion Boris Navachkov of California also still has a chance to win at 112, but will have a tough road now after falling to Missouri's Donte Butler on Monday. Butler was third at Junior Nationals last year.

Session IV of the Junior National Greco-Roman competition is set for Tuesday morning with the finals set for Tuesday afternoon.

Eng faces a tough challenge Tuesday morning when he meets FILA Junior World Team Trials champion and returning Cadet Nationals champion Eric Grajales of Oregon. The winner of the match advances to the finals with the loser wrestling for third place.

Alaska's Eli Hutchison advanced to the finals for the second straight year. Hutchison, second at Junior Nationals last year, is in the finals this year at 135. His sister, Michaela, reached the women's finals on Monday at 119 pounds.
