General None Reported / Taken
Environment - Non Weather Related; Human Factors
While descending on the EAGUL [arrival into] PHX we encountered wake turbulence following an A321 aircraft. I disconnected the autopilot to maintain control of the aircraft. This may have caused us to be high on making the altitude constraints (10;000 feet to 8;000 feet window at ESDEE). No comment made by ATC; nor were there any traffic conflict. Flight continued uneventfully to PHX.
A321 First Officer reported a wake vortex encounter on the EAGUL arrival into PHX that resulted in deviation from a crossing restriction.
