Julien Benneteau vs Adrian Mannarino prediction

I see great value on Mannarino against fellow countryman. 37 years old Benneteau came to R16 after 2 gualification matches + 2-1 victory over injury prone Berdych. He played 8 sets in 3 games. Victory over Berdych is 16th win in the last 50 games against Top-20 ranked players, 32 percent. However, he is still 2-9 on grass in his entire career. Grass is not his favourite condition that he got only the best position at semi-final game in 2007, 11 years ago. He failed to go further from R16 at ATP London in his 11 different attemtps. Mannarino has better stats, 59-39 on grass. Moreover, Mannarino is 25-11 on grass against lower ranked players, 70 percent. He had a great year on grass last season, final in Antalya and very solid performance at Wimbledon 2017. He passed F.Lopez, Sugita and Monfils when he had a chance of 4.50 , 4.30 and 1.95 odds. He eliminated by Djokovic, played 1 tie-break. It will be his 2nd grass event this year. I expect some better tennis than he had to quit after 1st game last week. He has more power, better records on grass.
