Victor Dubuisson one of three leading Open de France at halfway mark

Home favourite Victor Dubuisson has held on to his share of the lead after round two of the Alstom Open de France.

The world number 37 carded a one-under-par 70 at Le Golf National, which is the course for the 2018 Ryder Cup, to move to four-under for the tournament.

He shares the lead with Rafael Cabrera-Bello (70) and former US Open champion Martin Kaymer (69).

The trio are one shot off a group of five players that includes Italy's Francesco Molinari.

Graeme McDowell, who has won the tournament the last two years, missed the cut with a second round of 78 that included no birdies and two double bogeys.
