World Series of Fighting will make their California debut on Saturday, Aug. 10, at the Citizens Business Bank Arena in Ontario. The 10-bout WSOF 4 fight card is now complete.
In addition to the main card which was announced last week and is headlined with a light heavyweight match up between world kickboxing champion Tyrone “King of the Ring” Spong (1-0) and fellow hard-hitting knockout artist Angel “The Dream” DeAnda (11-2), the promotion has confirmed four new preliminary card bouts to round out the event.
Among those is a lightweight matchup between 43-year-old veteran Antonio “Mandingo” McKee (28-5-2) of Lakewood, Calif., and undefeated upstart “Lethal” Lewis Gonzalez (8-0) of Turlock, Calif.
McKee is best known for going on a 7-year unbeaten streak from 2003-2010 during which time he became the Maximum Fighting Championship lightweight champ. Most recently, The Bodyshop Fitness head trainer was on a three-fight tear before losing to Shinya Aoki via submission due to punches at Dream 18 this past December.
Gonazalez, 25, is a former two-time state high school wrestling champ and has been fighting professionally since Sept. 2011. He has finished seven of his eight opponents, including five wins via submission and two by knockout. This will be by far the biggest fight of his career.
Also added to the WSOF 4 prelims is a light heavyweight matchup between 31-year-old Lew “The Titan” Polley (12-4) of Los Angeles and 26-year-old Hans Stringer (21-5-2) of Zevenbergen, Netherlands.
Having been fighting professionally since 2006, Polley gained notoriety as an assistant coach for Team Dos Santos on The Ultimate Fighter 13. He comes into this fight off back-to-back wins, most recently defeating Carmelo Marrero via unanimous decision at Bellator 77 in Oct. 2012. Eight of Polley’s 12 wins have come via submission.
Stringer has been fighting professionally since 2005 and has been a lot more active than Polley in his career. Nine of his 21 wins have come via knockout, eight by submission and four decisions. Stringer is currently riding a four-fight win streak, most recently knocking out Marius Panin in the first round at Team Super Pro in December.
The two other additions to the preliminary card feature four California fighters with Cleber Luciano product Joe Murphy (6-1) vs. John Robles (7-1) at bantamweight, and Isaac “High Risk” Gutierrez (5-3) vs. Victor “Joe Boxer” Valenzuela (12-6-2) in a 150-pound catchweight fight.
The final preliminary card bout is a previously announced welterweight matchup between Jorge Santiago (25-11) of Boca Raton, Fla., and Gerald “Hurricane” Harris (21-5) of Tulsa, Okla. The five-fight preliminary card will stream live on WSOF.com on Aug. 10 starting at 8 p.m. ET (5 p.m. PT).
