De Alboran had a successful clay season last year, and he looks confident against more solid opponents now. An excellent indicator is victories over players of the top 200 level, specializing in slow surfaces.
Kruger has a higher rating, but this cannot be a key factor since it was achieved in fast courts. This player rarely performs on slow surfaces, so it's hard to believe the performance at this tournament will be good. In this sense, De Alboran's chances seem more probable.
Our prediction: De Alboran to win. We recommend the “1 Win” bet, odds 2.8
