The Cincinnati Open gets its Round of 128 underway on the hard courts of Cincinnati, with two matchups standing out on Tuesday's slate. A well-documented Dutch rivalry headlines the action, while an ATP first-meeting adds a layer of unpredictability to the day.

Botic Van De Zandschulp vs. Tallon Griekspoor - Round of 128

These two Dutch countrymen have built a substantial head-to-head record, with Griekspoor leading 4 wins to 2. Their five most recent meetings tell a back-and-forth story: Van De Zandschulp took a retirement victory at the Hamburg Challenger and a 7-6(5) 6-3 win at the Winston-Salem Open, while Griekspoor claimed the Amersfoort Challenger final, a straight-sets win at the Australian Open, and a Round 1 victory in Montpellier. Griekspoor holds a ranking advantage entering this match, sitting at No. 41 versus Van De Zandschulp at No. 55, which aligns with his overall edge in the rivalry. The hard-court setting in Cincinnati suits a match that has historically been competitive, though Griekspoor's three wins in the more recent meetings give him the momentum edge.

Prediction: Griekspoor to win in three sets.

J.J. Wolf vs. James Duckworth - Round of 128

This Round of 128 matchup represents a first-ever meeting between Wolf and Duckworth on the ATP tour, with no prior head-to-head results to draw from. Duckworth enters ranked No. 79, while Wolf's current ranking is unavailable in the data. With no H2H history and no odds listed, this is one of the harder matches on the slate to project with confidence. Duckworth's established ranking provides at least one concrete data point in his favor heading into Cincinnati.

Prediction: Duckworth to win, based on his ranked position.
