The catcher’s position might be the most physically demanding job on the diamond. Holding a semi-squatted stance while directing the pitcher for three hours straight is no easy task, and it takes a real toll on your knees the longer you stick with it. One way a lot of catchers try to fight off career-threatening knee damage is by wearing knee savers, a simple accessory strapped to the back of your shin guards to take some of the load off your joints.
As the name suggests, knee savers are meant to protect your knees. But there’s a long-running debate about how effective they actually are. Some players swear by them. Other coaches will tell you they do more harm than good. I’ve worn knee savers myself over the years, and I’ve also had coaches tell me flat out not to bother with them. If you want the short answer, it really comes down to your own body and playing style. Every catcher is different, and whether a knee saver makes sense for you is a personal call.
I’m not here to lecture you about mindset. I want to break down this debate honestly, using what I’ve learned from playing behind the plate and from talking with coaches and trainers, and show you why both sides dig in so hard. So, are knee savers really bad for catchers, or is that just a myth that won’t die? That’s what I’m digging into in this guide.
Do Professional Catchers Use Knee Savers?
It depends. Plenty of catchers prefer to play without knee savers, but a large chunk of them consider it a core piece of their equipment. From what I’ve found in my own research (and matches what I’ve seen firsthand), somewhere around 47 percent of MLB starting catchers wear knee savers during games. That’s close enough to a coin flip that you can’t point to the numbers alone and call it settled either way.
One pattern I have noticed: most of the guys wearing knee savers are veteran catchers who already have some mileage on their knees, not rookies straight out of college. That tells me players tend to reach for a knee saver once they actually feel a problem, rather than wearing one from day one just in case.
Primary Stance vs. Secondary Stance: When a Knee Saver Actually Helps
Here’s a distinction that clears up a lot of the confusion. Catching coaches generally talk about two stances. Your primary stance is the relaxed, comfortable crouch you use when there’s nobody on base and the count isn’t critical yet. Your secondary stance is the tight, ready-to-pounce position you drop into with runners moving or two strikes on the batter, when you need to block or throw immediately.
Knee savers only really come into play during that primary stance. Nobody is trying to block a ball in the dirt while resting on a knee saver, so the argument that they slow down your reaction time in the moments that matter doesn’t hold up if you’re using them correctly. Understanding that difference helped me a lot when I was deciding whether to add them to my own gear.
Should Catchers Wear Knee Savers?
Like I said, it mostly comes down to your situation and personal preference. I never touched knee savers when I was playing in little league or high school. It wasn’t until I got older and started feeling real, nagging pain from squatting through an entire game that I picked them up. So if you’re asking me directly, I’d only recommend using knee savers once you actually need the support.
Wearing a knee saver doesn’t magically make you a better catcher. That extra bit of cushioning might feel like a smart investment, but it’s not necessary unless your knees are already giving you trouble. If you’re young, fit, and full of energy, you probably don’t need one. If you’re getting older, still in decent shape, but starting to feel those joints complain, a knee saver is worth trying.
Should Youth Catchers Wear Knee Savers?
My honest answer is no. Unless a youth catcher is dealing with a diagnosed muscle injury or chronic knee pain, there’s no real reason for him to strap one on. A young player’s time is better spent building leg strength and training his body to hold proper catching posture without discomfort, not leaning on gear to compensate for muscles that haven’t developed yet.
Do Knee Savers Make Catchers Lazy?
A lot of coaches will tell you knee savers make catchers lazy. I understand where that opinion comes from, but I don’t fully agree with it. In my experience, gear doesn’t build or ruin work ethic. A pair of cleats doesn’t make you fast, and a knee saver doesn’t make you lazy. What actually determines whether a catcher is lazy is effort and attitude, not what’s strapped to his leg guards.
That said, I get why coaches worry. Comfort can get into a catcher’s head, and there’s a small amount of extra weight to deal with. But in my opinion, playing through constant knee discomfort is a far bigger problem than that. My take is simple. If you’re young and have plenty of healthy years left in your knees, skip the knee saver. You don’t need it to be a better catcher. But if you’ve got a real knee condition that affects your ability to catch, go ahead and use one without any guilt.
Why Do Catchers Have Bad Knees?
The semi-squat form a catcher has to hold isn’t easy to sustain, especially for hours on end in summer heat. The average baseball game runs about 3 hours and 5 minutes, and a catcher spends a huge chunk of that time crouched. Unless you’ve trained specifically for it, most people can’t hold a deep squat for more than a couple of minutes without their legs shaking. So it’s really no surprise that so many catchers develop knee issues the longer they stay in the position.
Some of the most common knee conditions catchers deal with are meniscus tears, patellar tendonitis, and muscle strains. Proper training and conditioning can prevent a lot of that damage, but the severity really depends on the player’s overall fitness. And it’s not just the hours of squatting either. You’ve got to factor in blocking balls at the plate, collisions on close plays at home, awkward rebounds off foul tips, and all the other unpredictable stuff a catcher takes on every single game.
To quote the late journalist Dan Rather: “To be a catcher is sort of like being a cowboy, without the romance of the Old West.” It’s hard, dirty, and often dangerous work, and old catchers, like old cowboys, tend to walk a little more gingerly than the rest of us. I think that line sums up the position better than almost anything I’ve read.
Do MLB Catchers Have Knee Problems?
Major League catchers go through intense workout and training routines to keep themselves in peak condition, and teams put real money and staff behind that training.
Because of that conditioning, MLB catchers tend to have fewer knee issues than a typical amateur player. Still, plenty of veterans develop knee problems as their careers wind down, which is a big reason so many switch to first base later on to take pressure off their joints. That’s not universal though. Plenty of catchers play the position their whole career without moving.
How do I strengthen My Knees as a Catcher?
If you want to play in the big leagues as a professional catcher, you need to take your physical conditioning seriously. Specifically, you need to build up your knees so you can hold that squatted position without pain or fatigue. Stretching before every session is non-negotiable. The last thing you want is to walk into practice cold and pull a muscle, so warm up properly before every game and let your muscles loosen up first.
To actually strengthen your knees, focus on workouts that build up the tendons and muscles around the joint. Squats are the obvious go-to. I’ve also found that single-leg squats do a lot for balance and knee strength specifically, more than a lot of catchers give them credit for.
Other solid exercises for knee strength include sit-to-stands, lunges, leg lifts, and side leg lifts. I like to mix in calf raises and step-ups too, since stronger calves translate into better posture behind the plate, and posture matters more than most young catchers realize.
If You Do Need a Knee Saver, Here’s a Quick Suggestion:
If you asked me which knee saver to buy, my answer is still the same one I’ve recommended for years: the Under Armour Knee Savers, officially sold as the UA Knee Supports. I’ve covered them before as part of my full breakdown of the best catcher’s gear, and while they’re not the flashiest option on the market, they’re the pair that has given me the most consistent day-to-day comfort.
Under Armour Knee Savers
These knee savers come in adult and youth sizing, so there’s an option whether you’re outfitting a high schooler or your own aging knees. Most knee savers on the market are basically glorified foam pads you strap onto your shin guards, and without a proper harness, they have a habit of sliding out of place mid-game. That’s one of the biggest complaints I hear from other catchers.
The Under Armour pair fixes that with a built-in sliding harness that anchors securely to your leg guards. Once you lock it in, it stays put, which makes a noticeable difference over the course of a long game or tournament weekend.
They also use a multi-level foam construction, which gives you real cushioning without feeling bulky. Even on days when my knees are barking a little more than usual, I can still get through a full game without it turning into a distraction.
One small thing I appreciate is that they come in a few different colorways, so you can match your uniform instead of being stuck with one plain option. It’s a minor detail, but for a lot of players, looking sharp on the field is part of the fun.
Overall, I’d give this pair a solid 4.8 out of 5. They’re reasonably priced, offer real support, and mount without needing any extra accessories. If you’ve decided you actually need a knee saver, this one deserves a spot on your shortlist.
Final Thoughts
Here’s the truth. Even the best catcher’s gear money can buy won’t fully protect your knees on its own. If you already have preexisting knee issues, playing without a knee saver could make it nearly impossible to enjoy the game long-term. My honest advice is to only use one if you actually need it. If you can still play the position comfortably and keep training your knees, relying on extra gear before you have to isn’t the smartest move. But if you’re dealing with real pain or a diagnosed condition, using a knee saver is absolutely fine, and I’d genuinely recommend it.
I hope this clears up the myths around knee savers for good. Now you know exactly when they help and when they don’t. Go strap on your gear, get behind the plate, and play like you know what you’re doing. Cheers!
