Tyrhys Dolan’s first-half effort was enough to separate the two sides as Mick McCarthy's men failed to even register a shot on target.
Here's how Pool’s players rated:

2. Chris Maxwell - 6/10
Given no chance for the goal but did well to deny Dolan with an earlier chance. Distribution was mixed again. Photo: CameraSport - Lee Parker
3. Jordan Gabriel - 6/10
Looked eager to impress on his first start since October. Almost got in early on with one of his driving runs. Photo: CameraSport - Alex Dodd
4. Callum Connolly - 6/10
Didn’t notice him a great deal. Not quite the swashbuckling display of Stoke but it wasn't that type of game. Photo: CameraSport - Alex Dodd
5. MAN OF THE MATCH: Curtis Nelson - 6/10
Defended pretty solidly. At least played on the front foot and tried to set the tone. Also a threat at the other end. Photo: CameraSport - Alex Dodd
6. Dom Thompson - 5/10
Conceded far too much space down the left for the goal. Somehow managed to finish the game despite picking up a knock. Photo: CameraSport - Lee Parker
