Just as the 100 knot call was made the aircraft swerved to the left. Attempted to bring aircraft back to centerline using right rudder; but aircraft continued left. Reject was announced and maneuver completed. Rejected takeoff (rejected takeoff) engaged and was released manually 3-4 seconds later. Max speed 110. Advised tower and we cleared the runway. Advised flight attendants to remain seated. After talking with station maintenance and maintenance control we taxied back to the gate.
