Half of the quarterfinals of Strikeforce's first-ever heavyweight grand prix tournament are now complete with Antonio "Bigfoot" Silva and Sergei Kharitonov moving on after pulling off a pair of memorable upsets.
Shane del Rosario, Chad Griggs and Valentijn Overeem also won a trio of reserve bouts, placing themselves as the frontrunners in case someone in the eight-man (now six-man) field is unable to compete.
After the jump are video interviews featuring four of the aforementioned fighters: Silva, Kharitonov, del Rosario and Overeem.
