Abraham’s penalty came after Roma had hit the woodwork four times and wasted a number of chances at Spezia, who had played most of the match with 10 men after defender Kelvin Amian was sent off at the end of the first half.
It was Roma’s first win in five matches and lifted them up to sixth, six points behind fourth-place Juventus. Spezia remain four points off the relegation zone. All Serie A matches have started five minutes late this weekend accompanied by a peace message following Russia’s invasion of Ukraine.
Roma coach Jose Mourinho was serving the first of a two-match suspension following his actions toward the referee during and after last week’s 2-2 draw against Hellas Verona.
Giovanni Simeone broke his goal drought in style with a second-half hat-trick to help Hellas Verona beat relegation-threatened Venezia 3-1.
They were Simeone’s first goals since mid-December.
David Okereke headed Venezia back into the match nine minutes from time but Simeone completed his hat-trick and sealed the result seven minutes later.
Venezia slipped into the drop zone, three points behind Cagliari after the Sardinian side won 2-1 at Torino.
