Juventus were left frustrated as they were held to a 0-0 draw at Parma.
• Serie A: Siena defeat Roma
Antonio Conte's men were well-rested coming into the game - which was postponed last month due to bad weather in Parma - as their fixture against Bologna on Sunday also fell foul of the adverse conditions in Italy.
However, although Juve had three penalty appeals denied and hit the woodwork through Giorgio Chiellini, they were forced to settle for a point. They remain in second spot, a point behind AC Milan, albeit still with a game in hand on the pacesetters.
Atalanta edged past Genoa 1-0 to claim their first home win since December 21.
Genoa were unlucky not to go in front in the 58th minute when Juraj Kucka's header from a corner struck the crossbar with goalkeeper Andrea Consigli already beaten, but Atalanta took the victory when substitute Guido Marilungo struck 12 minutes from time.
It is only Atalanta's second victory in seven games and lifts the club to 13th in the standings, nine points clear of the relegation zone.
