Petacchi joined the LPR Brakes team in August 2008
Alessandro Petacchi captured his second successive stage victory to secure the overall lead in the Giro d'Italia.
The 35-year-old eclipsed Britain's Mark Cavendish to claim the 198km third stage, from Grado to Valdobbiadene.
Petacchi clocked four hours 45 minutes and 27 seconds after the lead changed several times in the final minutes, with Tyler Farrar finishing second.
A late crash divided the main pack and Cavendish was affected, so is now one minute 25 seconds behind the leader.
Cavendish made history on Sunday by becoming the first Briton to claim the leader's pink jersey.
The mainly flat course in north-east Italy was more suited to the sprinters, but the 23-year-old slipped back from the leading group.
A group of five riders including Italy's Giuseppe Palumbo and Mauro Facci had led for most of the way but were caught by the peloton after 163 km.
Petacchi made the most of the crash near the front of the peloton around 10km from home that created two groups and distanced many of his sprint rivals.
In the final sprint he surged three bike lengths clear of the field and the late charging American Farrar could not catch him.
The mountains section begins on Tuesday, with an uphill finish to San Martino di Castrozza following a 162-km ride starting in Padua.
The race culminates in Rome on 31 May.
