LAS VEGAS – After years fighting some of the middleweight division’s top contenders, Gerald Meerschaert was up and down. The losses over a couple years came to names like Jack Hermansson, Kevin Holland, Ian Heinisch and Khamzat Chimaev – no shame among that lot. But now he’s on a three-fight winning streak, all by submission – but against opponents who might not be as big of names: Bartosz Fabinski, Makhmud Muradov and Dustin Stoltzfus
