Goals from Lee Cattermole and former Saddler Will Grigg were enough to cancel out Josh Gordon's fourth-minute opener and see the Black Cats close the gap to their promotion rivals.
Keates, who had opted to give on-loan Aston Villa winger Corey Blackett-Taylor a place in his starting line-up whilst giving top-scorer Andy Cook a place on the bench, praised his side for their first-half display but admitted that he was disappointed to leave the North East without at least a point to show for their efforts.
The result sees the Saddlers slip into the League One relegation zone for the first time this season. The Bescot Stadium side are level on points with 20th-placed Southend United.
