Pettini, a former England Under-19 international, is a talented opening batsman thanks in part to his elegant stroke-making.
After his Essex debut in the final County Championship game of the 2001 season, Pettini’s appearances were limited largely to the limited-overs arena until 2006, a summer which saw him register his maiden first-class hundred - against Somerset at Taunton in May.
He was an ever-present in the championship side that summer, and an unbeaten 208 against Derbyshire late in the campaign contributed to his tally of 1,125 runs at an average of 45.
He also played his part in Essex winning the NatWest Pro40 title in 2006, and was appointed captain following Ronnie Irani's retirement through injury midway through the 2007 season. Pettini had skippered the side for much of the summer in Irani's absence.
Pettini began the 2008 season with a blistering 144 off 120 balls against Surrey in the FP Trophy - he shared an opening stand of 269 with Jason Gallian as Essex amassed 391 for five - but he failed to reach three figures again that summer.
However, any personal disappointment was softened by Essex winning the Trophy as well as the NatWest Pro40 Division Two title.
Pettini’s form dipped in the 2010 season with an average of just 24 and, in the following year, he struggled to make the team, featuring in only half of his side’s 16 four-day matches.
He showed indications of a return to his best in 2012, with a tremendous run-a-ball century against Worcestershire.
