Lucas Torreira was the star with two spectacular Sampdoria goals, but Chievo will feel the 4-1 result is far too harsh for their performance.
The Blucerchiati had to get back on track after a tight 3-2 defeat to Inter on Tuesday evening and had a full squad to choose from, as Emiliano Viviano returned in goal for the hosts, but the Flying Donkeys were fresh from their own 4-1 loss to Milan and Perparim Hetemaj was suspended.
Riccardo Meggiorini made his first start since tearing an ACL in April and almost marked it with an opening goal, turning inches wide of the far post on a Valter Birsa counter-attack.
Meggiorini burst down the right and pulled back for Samuel Bastien, who slipped and ballooned over under pressure from Jacopo Sala.
Instead, Sampdoria broke through first when Fabio Quagliarella’s turn and shot turned into an assist for Karol Linetty to blast under the bar with his left foot.
Chievo got their deserved equaliser from a set play, as Birsa’s corner found ex-Sampdoria defender Fabrizio Cacciatore for a towering header.
Barely 120 seconds had passed before Samp restored their advantage in spectacular style. Lucas Torreira was brought down a good 30 metres from goal and hit a missile that dipped viciously under the bar.
They were still celebrating when Chievo nearly scored again, Meggiorini dribbling past two defenders in the box to see Viviano deflect the finish from point-blank range.
It was non-stop action at Marassi, Viviano fingertipping a Roberto Inglese stop and volley off target, Linetty’s half-volley flashing just wide and Inglese’s effort turned round the post.
Lucas Castro’s diving volley on a Massimo Gobbi cross was off target at the back post and moments later Sampdoria added a third goal.
Quagliarella ran on to a Gianluca Caprari through ball down the right and pulled it across the face of goal for Duvan Zapata to tap in.
There was a Quagliarella lob off target and Gaston Ramirez’s snapshot was beaten away by Stefano Sorrentino, the goalkeeper also denying Quagliarella from a Sala cross.
Cacciatore was booked for dissent, soon followed by Chievo Coach Rolando Maran, but Sampdoria added a fourth with Torreira completing his brace.
The young Uruguayan hit a ferocious volley from the edge of the box that flew through the legs of Gian Marco Ferrari.
