UFC Undisputed 2009 Transition Help?

OK so my record is about 130-65 which isn't all that great but i have recently found out that im way better in L.H my record there is 75-9 but i lately have run into people who all they do is hold the og stick back to block the transitions in the mount and wear down my stamina so they either ko me with ground and pound or i get submitted. Is there anyway to get them off of me if all they do is hold the og back? I use Wanderlei SIlva.
