The American's best result of the season came at the ATX Open, where she won the title with a 7-5, 6-2 win over McCartney Kessler in the final. At the Miami Open, she received an opening-round bye due to her seeding and began her campaign with a 6-4, 6-4 win over Bernarda Pera in the second round.

Jessica Pegula vs Marta Kostyuk prediction

In her previous match against Kalinskaya, Pegula won 69 and 41 percent of her service and return points, respectively. The American won 82 percent of her first serve points, but her second serve was not as efficient as she got broken twice.

Meanwhile, Kostyuk won 63 percent and 54 percent of her service and return points against Blinkova in the previous match. The Ukrainian attacked the second serve during return games, winning 69 percent of the second-serve return points.

For Pegula the key to winning this match is to make as many first serves as possible as Kostyuk will be able to attack the second serve. Meanwhile, the 23rd seed has to hold her serve and not make too many unforced errors. Pegula will be the favorite as she is the fourth seed and has a good record in Miami.

Pick- Pegula to win in three sets
