Gianluca Sansone replied to Alberto Gilardino, as Bologna and Sampdoria shared the spoils.
Both sides were practically safe already, but wanted a few extra points to be sure. Alessandro Diamanti shook off an injury, though Diego Perez was still out and Gyorgy Garics suspended. Andrea Costa and Lorenzo De Silvestri sat out bans for Samp, while Nenad Krsticic and Eder were sidelined.
The Blucerchiati’s last Serie A victory at the Dall’Ara was in November 2003, but three of the last four meetings had been draws. In honour of Earth Day, Bologna wore an all-green strip.
Alberto Gilardino spun round, forcing Sergio Romero to palm it over the bar, then from the corner the goalkeeper was again tested by Sansone from point-blank range.
Bologna were forced to replace Niccolo’ Cherubin with Frederik Sorensen after just 21 minutes.
Gilardino broke the deadlock when he crouched down in the six-yard box to get a glancing header to Saphir Taider’s cross from the left. The crowd celebrated Bologna’s 3,000th Serie A goal.
Samp lost Mauro Icardi to injury, introducing Maxi Lopez instead, while Romero denied Panagiotis Kone a second.
Bologna came out fighting for the second half, as Taider’s right-foot shot was deflected out from a corner and Alessandro Diamanti tested Romero directly from the flag.
Sampdoria drew level just shy of the hour mark when Sansone ran into the box and smashed an angled drive across the goalkeeper.
A late Diamanti free kick was deflected wide off Gianni Munari.
