Stewart bagged 24 goals for the Black Cats last season, a total only beaten by Wigan Athletic’s Will Keane throughout the campaign.
The efforts of both these men mean they will be playing Championship football next season.
Stewart’s great form in-front of goal has also earned him a call-up to represent Scotland, coming on for his debut against Armenia in the Nations League earlier this week.
This capped off a wonderful season for the 25-year-old, but how did his form across the year compare with other strikers in the division?
Here, using average ratings provided by WhoScored.com, we take a look at which front men had the highest average ratings in League One last season to see where Stewart ranks among them.
