Musetti-Faria in Cincinnati: why the Portuguese needs short rallies

Jaime Faria comes into tonight's round of 16 with five matches in his legs in a week, two in qualifying and three in the main draw, the last one closed in a third-set tiebreak after more than two hours against Adam Walton. Lorenzo Musetti, who entered play in the second round as the 10th seed, has played two matches, both closed in two sets. Freshness matters, but what matters more is the type of point the Portuguese has won so far: short ones, off a fast ball to send back. Musetti won't give him that ball.

The plan that beat Shelton here can't be repeated

Against Ben Shelton, the world No. 6 and fresh off winning Montreal, Faria won 6-4, 6-4 doing exactly what his profile suggests: absorbing his opponent's pace and sending it back, with the forehand and with the two-handed backhand down the line. The number that explains the match is the one for service games.

Break points saved by Faria against Shelton: 11 of 12.

The same pattern worked against Jenson Brooksby (6-3, 6-2 in an hour and fourteen minutes) and, with more effort, against Walton. In all three matches, Faria's work was about redirection, not construction.

Musetti offers the reverse. His serve isn't a weapon that forces you into an emergency return, and from the baseline he works on height, spin, backhand slice and drop shots. To do damage, Faria will have to generate his own pace starting from low or floating balls. It's the shot he's practiced least this week.

Where Musetti runs up the tab

Against Michael Zheng, Musetti dominated the return games for the entire match and closed it out in just over an hour (6-1, 6-3). Against Daniel Altmaier, two days earlier, he'd won 6-4, 6-2, building almost everything off his opponent's second serve. The target is the same tonight: the serve remains the most attackable part of Faria's game, and it's the surface where Musetti attacks best when he's physically right.

Then there's the court factor. Cincinnati has slowed down this year: the court speed index has dropped from over 43 to 38.1. If the evening session, with Ohio's humidity, takes even more off the fast ball, the average rally gets longer. Every extra shot is a tax Faria pays with interest, and Musetti's backhand slice exists for exactly this: forcing a two-hander to lift the ball back up from below, on legs that have played five matches this week.

The two have never met. Musetti is chasing his first quarterfinal in Cincinnati, his third Masters 1000 round of 16 this season after Madrid and Rome, having skipped Roland Garros and Wimbledon with a rectus femoris injury in his left thigh picked up at the Italian Open.

The forecast, and what could prove it wrong

Musetti is the clear favorite, with a straight-sets win the likeliest scenario if he closes out the first set quickly. The condition that could disprove it has a precise name: his first serve. In Washington he won the first set 6-1 against Rafael Jodar, then lost precision on serve and dropped it 1-6, 4-6; a few days later, in Montreal, Jodar beat him again 6-4, 6-3. If Musetti's first-serve percentage drops below what he posted against Altmaier and Zheng, he hands Faria exactly what the Portuguese does best: attacking a second serve and taking the center of the court.

The second signal to watch is the first-set score. If Faria takes it to a tiebreak, the mileage argument deflates and the match turns into a head-to-head on his forehand.
