Medvedev vs Wawrinka prediction

Daniil Medvedev takes on Stan Wawrinka in the first round of Wimbledon. Wawrinka is not playing so well on grass, this surface more fit to Medvedev, but still I expect Wawrinka to win here. He has played only in London on grass surface this season where he lost to Lopez in the first round, but Wawrinka is always playing on higher level on Grand Slams so I expect from him to raise his level of play on this tournament. Last season he wasn’t lucky and met Del Potro in the 2nd round but before that he has played 2 times in the quarterfinal so he surely can make another good result here. Medvedev is good on grass, he has 9-3 record on this surface this season, played very well in Eastbourne last week where he reached semifinal. He has a good serve, playing aggressive, but still he in unreliable and I cant trust him. Overall quality and experience are still on Wawrinka side, so I will take Stan to win in 3 or 4 sets.
