The World Series of Fighting will attempt to continue building momentum on August 10 when the organization puts on its fourth show. This time around, the company will venture to Ontario, California instead of set up shop in Las Vegas and present a lineup featuring more than a few familiar faces.

With Tyson Griffin-Gesias Cavalcante already on tap, as well as an in-ring appearances from promotional President Ray Sefo and kickboxing star Tyrone Spong, three new tilts have been announced for WSOF 4. Specifically, UFC veterans Jorge Santiago and Gerald Harris will hook up, while Nick Newell battles TUF 13 alumnus Keon Caldwell and bantamweight Marlon Moraes (10-4-1) mixes it up with Brandon Hempleman (9-1).

Despite his struggles in the Octagon, the 25-11 Santiago has been impressive for the most part throughout his career with past success against Siyar Bahadurzada, Mamed Khalidov, and Kazuo Misaki. All but two of his wins have come by way of a stoppage. Comparably, Harris holds an overall record of 21-5 with four triumphs in his last five fights.

Newell is a former XFC champion with a 9-0 mark and eight finishes to his credit. Also notable, Newell’s success has come without the use of his left forearm based on a birth defect. His opponent, Caldwell, is 9-1 with knockouts in his last two tilts.
