Common Hitting Injuries
Also known as: hitting injuries, side hurts when I swing, oblique strain, oblique strain baseball, hamate fracture, lower back pain from hitting, wrist pain from hitting, swinging injuries
Common hitting injuries include oblique (side) strains, hook of the hamate fractures in the hand, low back trouble and sore wrists. They often follow sudden jumps in swing volume, poor warm-ups or a body area that lacks strength or mobility. Stop swinging if something hurts, and see a qualified medical professional for pain that persists.
An oblique strain is a pulled muscle along the side of the trunk. In hitters it often follows a hard swing or a sudden jump in the number of swings. Data from MLB injury tracking show most oblique injuries happen on the lead side, the side facing the pitcher. Fatigue, a weak trunk and too many swings too soon are common contributing factors.
The hamate is a small wrist bone with a hook near the base of the palm. The knob can press into it in the bottom hand. A fracture there makes the pinky side of the palm tender, especially when gripping or swinging. Standard X-rays can miss it. Sore wrists can also build up with high swing volume.
Habits that help include building swing volume gradually, warming up before hitting, and training trunk strength and hip mobility. Use a bat you can control and a grip that does not jam the knob into the palm. These steps lower risk but cannot remove it. Get checked if symptoms persist, get worse or affect grip.
Tips by skill level
Warm up before you hit and add swings a little at a time. Stop if anything hurts.
Track weekly swing counts. Big jumps from one week to the next are worth avoiding, especially before tryouts or the season.
Example
A high school hitter doubles his swings the week before tryouts and feels a sharp twinge in his left side, the side facing the pitcher. He stops swinging and sees a sports medicine doctor. He returns after rest and rehab with a plan to build swings more slowly.
Why it matters
Hitting injuries can cost weeks or months. Knowing the warning signs helps players stop early and get checked.
Common mistakes
- Swinging through side soreness
- Doubling swing volume right before the season
- Ignoring a tender spot at the base of the palm
- Skipping warm-ups before hitting
Frequently asked questions
Why does my side hurt when I swing?
It could be a strained oblique, a muscle along the side of your trunk. Hitters often strain the side facing the pitcher. Stop swinging and see a qualified medical professional if it doesn't settle down.
Why does the bottom of my hand hurt after hitting?
Soreness on the pinky side of the palm can come from the knob pressing on the hamate bone. It can be a fracture, so get it checked if it lasts.
Should I keep hitting if my back hurts?
No. Stop and rest, and get checked by a doctor or athletic trainer if it continues. Pushing through it can make an injury worse.

- Strength Training for Bat SpeedStrength training can raise bat speed by building the legs, hips and trunk that drive the swing. Many programs pair basic lifts such as squats, hinges and presses with rotational medicine-ball throws done at full speed. Young athletes should learn form with light loads under qualified supervision.
- Hip and Thoracic Mobility for HittersHip and upper-back (thoracic) mobility let a hitter turn the pelvis and shoulders separately and hold posture through the swing. Tight hips can limit how far the pelvis turns at landing. A stiff upper back can limit shoulder turn during the load. Short, regular work such as 90/90 switches and open-book rotations helps many hitters.
- Bat StingBat sting is the painful buzz you feel when the ball meets the bat away from its sweet spot. The impact makes the bat vibrate, and the vibration runs down the handle into your hands. Contact off the end of the barrel tends to buzz the bottom hand, while contact toward the thin part of the bat stings the top hand between the thumb and index finger. Squarer contact is the real fix; batting gloves and bats built to damp vibration soften it.
- Warm-Up ProtocolA warm-up protocol is a structured routine that prepares the body for full-effort swings. It raises tissue temperature, activates relevant muscle groups, and syncs the nervous system.
- Recovery SessionA recovery session is a low-intensity practice day focused on reinforcing patterns at slow speed, flushing fatigue, and keeping motor grooves active without accumulating more load.
