Nova União featherweight Marlon Sandro (11-0) leaped into Pancrase’s top spot in that weight class Wednesday night at Korakuen Hall in Tokyo after nailing second-ranked Miki Shida (13-5-2) with a flying knee in the final minute of the second round. The fighters were competing for the 66-kilo King of Pancrase title vacated by Yoshiro Maeda (23-4-2), who debuted successfully in the WEC in February. Sandro followed his knee strike with a typhoon of fists that finished dazed Shida at 4:19 of the round.  The stoppage was Sandro’s first since 2005. Earlier in the night, Sandro’s training partner and cousin Hacran Dias (7-0-1) scrapped with Takafumi Ito (33-26-10) to a draw in a 77-kilogram match.  Dias was debuting in Pancrase versus 13-year Pancrase vet Ito.

Middleweights Takanori Sato (5-4-4) and Masahiro Toryu (4-3-3) fought to a draw. Welterweight Tomoyoshi Iwamiya (4-6) won a unanimous decision over Asaki Honda (4-2-1). ...
