Enzo Crivelli scored the second-half winner for Bastia but was sent off three minutes later in his team's 1-0 Ligue 1 win at home to Guingamp.Both teams finished with 10 men, Guingamp the first to feel the heat after defender Marcal was sent off for a second bookable offence seven minutes before half-time.The hosts made it count 14 minutes from the final whistle, when Crivelli was set up by his fellow forward Lassana Coulibaly.But he was gone too soon afterwards, also for a second yellow card, leaving Francois Ciccolini's hosts to hang on themselves and close the gap on their opponents to one point.
