He came into the tournament as a lucky loser, after retiring due to an ankle injury in the first set of his final qualifying match against Damir Dzumhur.Otte does have a lot of good wins in recent weeks, but if he is not fully fit against Diego Schwartzman on Thursday, he may not have too many chances to get a foothold in the match.Known to be one of the hardest working and nicest guys on tour, Schwartzman's recent success is well-deserved. The Argentine moves like a bunny rabbit, can counterpunch from the back of the court with great effect, and has learnt to turn defense into offense incredibly well over the past couple of seasons.Prediction: Diego Schwartzman to win in straight sets.
