Reviewer slates them, including the pitchers (5)
I believe the answer is:
ewers
'pitchers' is the definition.
('ewer' can be a synonym of 'pitcher')
'reviewer slates them including' is the wordplay.
'including' indicates a hidden word.
'EWERS' is hidden within 'reviewer slates them'.
'the' acts as a link.
(Other definitions for ewers that I've seen before include "Vase-shaped jugs" , "Large jugs" , "Pitchers" , "Water jugs" , "Jugs thrown into sewer" .)
