Is there any way to keep a fish from running to the weeds once he grabs the hook?

Running is a typical response when the fish actually grabs the hook and begins to feel pressure from the line.  If you’re close to an area that will provide cover, that’s usually going to be when he tries to go.  Occasionally, you can keep this from happening if you by releasing the pressure.  I’d only suggest using this technique if the fish is trying to run to an area of kelp, rocks or weeds that may result in a bust off.  To try this though, you need a excellent drag system and you’ve got to be aware of your drag settings.  If you’re using a lever drag, try backing off a little.  Lever drags are much more precise than star drags and you can return the fish-fighting drag fairly accurately.  When he stops running, you need to ease up slightly and try to lead him instead of pull him away from the area you don’t want him to get into to.  If he attempts to run again, you’ll have to start all over.  Your goal here is not to pull him into the boat but to direct him away from the area where you’ll risk losing him.  Once you can get him away from that spot and into open water, the fight is on.
