Aircraft
This trip is actually the continuation of Aircraft X; on date; the day following our weather divert to ZZZ.While beginning our descent on the ZZZZZ 4 arrival into ZZZ1 the FO (PF) deployed the speed brakes to approx 50% in order to comply with the altitude restriction. When the FO stowed the Speed Brakes the aircraft abruptly rolled 35 degrees to the left. The autopilot had difficulty controlling the aircraft so we disconnected and FO flew manually. The FO quickly and accurately corrected the left-roll tendency with right ailerons; leveled the wings and continued the arrival. Simultaneously to these events the SPOILERS EICAS illuminated. We slowed to 250 KIAS to minimize the left-roll tendency and informed ATC. We decided to have the FO continue to fly and handle radios while I ran the non-normal checklist; coordinated with Dispatch and Maintenance and ran the TEST with the Lead Flight Attendant. After finishing the SPOILERS EICAS checklist and the other coordination was complete it was determined that some of the spoilers on the left wing remained in the UP position and would not stow. I opted to request priority handling and requested the ILS to Runway XXC with a long; 20 mile final; which ATC coordinated. We then gradually slowed and configured the aircraft; determining the aircraft controllability with each configuration change. Once final landing configuration (Flaps 30) and target speed were established the aircraft continued the left-roll tendency but was manageable. The FO accurately noted that at target speed the speed tape showed little margin above stick shaker activation; so we opted to add 10 Knots to our target speed. I believe this was due to the spoilers still extended on the left wing. The remainder of the approach and landing being uneventful as the FO made an excellent landing. I took the aircraft on the rollout and we met the responding Emergency personnel. They checked us over and we taxied to the gate.
Flight Crew reported a spoiler issue caused aircraft controllability issues which resulted in a precautionary landing.
