Unbeaten lightweight prospect Dave Jansen submitted Amirkhan Mazikhov with a first-round guillotine choke, as Team USA West cruised to a 5-0 victory against Team Russia Imperial at M-1 Challenge 17 on Saturday at Olympic Hall in Seoul, South Korea.

Jansen (12-0) needed only 22 ticks to lock in his fight-ending guillotine choke against Mazikhov. The Sportfight veteran and Team Quest product has finished three of his last five opponents. Jansen has won all three of his bouts on the M-1 Challenge circuit.

Competing on Independence Day, all five Americans finished their Russian counterparts, three of them inside the first round.

EliteXC veteran Givanildo Santana coaxed a tapout from Radmir Gabdulin with an arm triangle choke in 3:47. Santana (13-1) has delivered all but one of his career victories by submission and has taken the moniker “The Arm Collector” for his ability to put away opponents with armbars.

Other victors for Team USA West were undefeated heavyweight Shane del Rosario, Affliction veteran Fabio Nascimento and Tony Lopez. Del Rosario (7-0), a Team Oyama product, stopped Maksim Grishin on strikes in a mere 21 seconds.

With its clean sweep of the Russians, Team USA West became the first squad to clinch a spot in the M-1 Challenge semi-finals.
