Maks Kasnikowski vs Aidan Mayo Prediction, Odds, Best Bets - Sioux Falls Challenger 100

The eighth seed arrives off a semifinal run in Olbia and a 6-1, 6-2 first round here. His opponent is an alternate entry who played three three-set matches last week and has a habit of dragging favorites into deciding sets.

The Matchup

This is a second-round match at the Sioux Falls Challenger 100, an ATP Challenger event one tier below the main ATP Tour, played on indoor hard courts at the Huether Family Match Pointe. Maks Kasnikowski is the eighth seed and ranked No. 214, with a 45-27 record this season built across a full year of Challenger draws. Aidan Mayo is an alternate entry ranked No. 341, and he took the direct route here, beating Hynek Barton 6-2, 6-3 on Tuesday.

Kasnikowski's autumn has been played at this level and mostly won. Two weeks ago in Olbia he beat Cezar Cretu 6-2, 6-1, Andrea Guerrieri 6-3, 6-4 and Stefano Travaglia 6-2, 7-5 to reach the semifinal, where Damir Dzumhur stopped him 6-1, 7-5 on October 17. He took ten days off after that, came to Sioux Falls, and beat qualifier James Trotter 6-1, 6-2 in the first round.

Mayo's road has been busier. He reached the quarterfinals at his last two Challenger events, Columbus and Fort Worth, and his Fort Worth week ran long: three matches, all of them decided in a third set, ending with a quarterfinal loss to Sander Jong that finished in two tiebreaks. Neither man has a retirement in his recent record, and both finished their first rounds here in straight sets.

Key Factors

The margins are the mechanism behind the pick. Kasnikowski's four wins across Olbia and Sioux Falls came by nine, five, six and nine games, because his two-handed backhand takes the return early and the games stack up once he gets ahead. He does not edge matches at this level when he is in this form. Mayo's route into this match runs the other way: he survives. He came from a set down to beat Kaylan Bigun at Fort Worth, and his matches keep stretching because his serve and his nerve hold up under pressure.

The surface numbers are thin on both sides and the pick does not pretend otherwise. Kasnikowski is 5-3 on indoor hard this season and Mayo is 2-1, too few matches to build anything on.

What the pick rests on is level and freshness: a top-220 regular with 45 wins this season against an alternate entry whose ranking is the honest summary of his year, and a man who arrived rested, one semifinal in the last two weeks, against one who played three long matches last week. Mayo is a two-time Challenger champion, most recently in Kingston in August as a lucky loser, so none of this is new to him.

What beats the pick is Mayo's October. He has beaten Colton Smith, a top-220 player, twice this month, in Columbus and again at Fort Worth, and the Jong loss says he is playing close to that level right now.

If he holds serve through the first set and turns this into another of his long afternoons, a margin of two and a half games can disappear in one loose service game. Kasnikowski has dropped that kind of match this autumn, losing his opener at Villena to a qualifier. The winner is not really the question here. The width is.
