First half, Sarries were simply outmuscling Bath, but our backs were doing their best to even things up, albeit with our usual inability to convert pressure into points.
Inevitably there's only so long that can last for, and being outmuscled up front will always lead to a high penalty count - which gets you less leeway from the ref.
Half time was when heads dropped, systems failed, penalites skyrocketed, and Sarries were gifted an extra gear (not convinced they found it, more that we dropped away)
