Wilson Ultra 99 Pro v5 Tennis Racquet Review

The Wilson Ultra 99 Pro v5 is the most control-oriented racquet in Wilson's power line, and the one to hand a Blade player who wants more muscle. A thinner, stiffer 99 with an open 16x18 pattern that adds spin and forgiveness, and a medium balance built to drive groundstrokes.

An Ultra for Blade players

The 99 Pro is the Ultra you reach for when you want the line's power but more command over it. Wilson built it on the old Steam 99 mold, a stiff, tapered beam that is a study in power and stability, and gave it a 99 square inch head for a tighter, more connected response than the Ultra 100. The result is a genuine step up in control that still punches harder than a classic player's frame. This model is endorsed by several touring pros such as Alex de Minaur, and Marta Kostyuk.

That is the pitch our testers kept making. One plays a Blade day to day and expected the two to feel similar, but the 99 Pro packs a noticeably bigger punch and better spin. If you like a Blade but wish it hit harder, this is the frame that scratches that itch, a control-leaning racquet with real Ultra power underneath.

The 16x18, and why it's here

The unusual part is the string pattern. An open 16x18 on a stiff, powerful frame is a deliberate choice: it lets the strings move and snap back for spin, and it adds the forgiveness and net clearance that a stiff frame usually lacks. Wilson calls it essential for a high-stiffness racquet, and on court you feel why. The ball comes off higher, with built-in margin over the net.

The flip side is that you have to commit. Because the frame is powerful and the ball launches higher, you cannot stop your swing short, or it floats long. Our testers found themselves leaning on the 16x18 to brush the ball and spin it down into the court, which is exactly how you get the best out of it. Supply the intent, and it rewards you with heavy, spin-loaded shots, especially if you naturally hit a little flatter and want more pop.

What version 5 brings

The core tech is SI3D Elite, Wilson's power-flex layup tuned for explosive power at high swing speeds while balancing court penetration and control. Inner hoop power grooves add energy transfer and an explosive feel on contact, and a Dual Taper Beam blends power with maneuverability. Wilson also gave the 99 Pro a higher balance than most modern frames, a little less head-light, which loads up groundstrokes and the two-handed backhand.

The generational upgrades carry over from the rest of the line: tighter spec tolerances for consistency, the Click-and-Go bumper for easy grommet swaps, and the glossy Electric Indigo blue that our testers, and most reviewers, rate as one of the best cosmetics of the year.

How it plays

The 99 Pro plays like a powerful frame that has been talked into behaving. It asks for a full, fast swing and gives back pace, spin, and a rock-solid, predictable response.

Quick-strike power

Power is the first thing you feel. Despite the Pro label and the control lean, this is not a low-powered player's frame. It delivers quick-strike pace, and it rewards a player who generates power on the move. It sits closer to a Head Extreme or a Yonex VCORE for pop than to a pure control stick, which is the whole point of an Ultra.

Spin, and keeping it in

The 16x18 and the power grooves give you the spin to manage that power. The ball leaves the string bed with more height and rotation, so you get net clearance and margin, provided you keep swinging through. It is a frame that pays off a committed, brushing stroke and punishes a tentative one.

Stable, and a serve you can trust

The slightly head-light balance and the roughly 327 swing weight make the 99 Pro stable, both against a big hitter and on your own groundstrokes. Our testers found it solid on volleys and easy to serve with, the kind of frame you can lean on to finish a point at the net. That stability is a big part of why it holds up at an advanced level.

Strings and setup

The 99 Pro is stiff and powerful, so most players will want a control string to keep it honest. A shaped co-poly rewards the brushing, spin-first stroke the 16x18 is built for, and stringing toward the upper end of the range tightens the response on a frame that can otherwise launch the ball long. If the stiffness starts to bother your arm, a softer poly takes the edge off without killing the pop, and a slightly lower tension gives you back a little of the easy depth.

99 Pro or 100?

The 99 Pro is the control-and-spin choice, thinner in the beam, head-heavier and more demanding, for a stronger player who supplies their own pace. If you want easier, more forgiving power from a bigger, softer frame, the Ultra 100 is the friendlier one. And if you want pure control ahead of power, the Blade is worth a look, though the 99 Pro exists precisely for the Blade player who wants more.

Who should swing it

The 99 Pro is for intermediate to advanced players with full, fast swings who want power and spin from a control-leaning frame. The 16x18 pattern and power grooves add pop and spin, especially for a flatter hitter, and the slight head-light balance drives the forehand and the two-handed backhand. It is the logical progression from the Ultra 100 for a player who has outgrown it.

It is not a beginner's racquet. The frame is stiffer, and it asks you to keep the ball in with your own spin rather than doing it for you. If that sounds like work, the Ultra 100 gives you the same family's power with far more forgiveness, and a control purist will still prefer the Blade. But for a strong player who wants an Ultra that hits big and stays in, the 99 Pro is a genuinely unique frame.
