I was starting day two of a pairing and going through the Captain's preflight setup. Out of old habits; I did a standby rudder check and found that the rudder did not move and the Low Hydraulic light (standby system) was on. I coordinated with Dispatch and Maintenance Control; and then called Contract Maintenance. A circuit breaker was found popped in the E & E bay. It was reset and the standby hydraulic pump worked normally. The standby rudder check is no longer part of the Captain's flows; sometimes I forget and revert to old habits. That was the case in this situation.  Perhaps consideration should be given to adding the standby rudder check back to the Captain's preflight flows.
B737 Captain reports discovering a failed standby hydraulic pump during preflight; which is no longer part of the normal preflight checks. Maintenance is called and tripped circuit breakers are found in the forward electronics bay.
