What are you talking about? She can't stop his ability to project, and any weapon he traces he can make it move like it was originally wielded. With all the speed and strength that involves. Literally all he has to do is trace any weapon used by a HS that isn't complete shit and she's fucked and it's automatically a draw. She doesn't have the stats or defenses to even get in his range if he does it given she uses her fists and the weapon can react to attacks that Shirou himself can't as seen in the Berserker fight. If she uses Frag without it being against a trump it's a D rank attack that the same weapon could react to and stop (hell his internal armor shit could stop that dead).
Literally the only way Bazett could beat a Shirou that doesn't suddenly forgot half his skillset is if tracing counted as his trump, but in that case the VS would be "He traces then dies", not the shit Nasu said about her being good against magus and experienced and Shirou's a magus so he loses. Even though Shirou is further from being a conventional magus than she is. Plus Archer's trump is explicitly Broken Phantasms.
