Green returned to the 18th hole for the playoff and made birdie to pick up the win. Green closed with a one-under 70 in the final round, while Remesy fired a seven-under 64 to force the playoff.
This event is in its fifth year as part of the European Tour's International schedule. The first 13 years, the tournament was part of the Challenge Tour.
Green is back to defend his title, while two-time winner here Markus Brier will also tee it up at Fontana Golf Club this week.
The GOLF CHANNEL will have three hours of coverage all four days.
Next week most of the top players in the world will be at the U.S. Open. For those not making that field, the European Tour has the Saint Omer Open, where Carl Suneson won last year.
