Forecast: Persell to win. Persell looks more stable than Busta and hasn't had a grueling string of matches like Corda. Persell's serving statistics also inspire more confidence than Busta's. With equal odds, I believe Persell has the advantage and can secure the victory.
In the 1/16 final match of the tournament in Cincinnati, Max Purcell will face Pablo Carreno Busta. Purcell showed a good game by defeating Tomas Machac. However, the Spaniard Carreno Busta has returned from injury and surprised with a victory over Corda. Carreno Busta has more experience, he is stronger on the baseline, and is building his form. Therefore, I lean towards Pablo Carreno Busta winning this match.
