You throw the rear hook, they lean or slip outside, and the lane under the chin opens for a beat. A lead uppercut after the rear hook slips outside turns their escape into your next shot instead of a reset they own.
This is a tight pocket sequence, not a wild shovel punch from the parking lot.
Throw the rear hook to draw the outside slip
The rear hook must be real enough to make them move. Soft feints get ignored. Short, tight hook across their guard line. Build rear-hand honesty from slip outside their jab then fire the rear straight so they already respect that side.
If they always slip outside your rear hook, you have a read. Do not chase the hook wider. Keep it short and prepare the uppercut lane.
Uppercut up the middle as they clear
As their head clears outside the hook, your lead hand is already under the chin line. Palm up, elbow in, short arc. Long uppercuts get timed and countered. Think lift, not haymaker.
Weight stays balanced enough to plant. Falling into the shot after a missed hook is how you eat the return. Pocket discipline from lead hook from the pocket without early telegraphs keeps both hands honest.
Keep the rear hand home on the exit
After the uppercut, rear glove returns high. They may fire a cross or hook off the slip. Chin tucked, eyes up. The combination is hook-uppercut-cover, not hook-uppercut-admire.
If the uppercut lands clean, you still leave on purpose. Standing in the pocket to celebrate is optional only in highlight reels.
Do not force it when they slip inside
Inside slips change the geometry. The lead uppercut lane may not open. Mix body shots, check hooks, and exits instead of forcing the same third punch. Variety keeps the sequence rare and sharp.
Pair exits with footwork resets after missed lead hand shots when the uppercut whiffs so you do not linger on the edge.
Drill the timing at controlled power
Partner slips outside a rear hook on a known rhythm. You fire one lead uppercut per wave, then cover. Film whether the uppercut is short and whether your rear hand is home. Power comes after timing.
Alternate orthodox and southpaw so the first southpaw slip in sparring is not a surprise. Adjust which shoulder clears and where the uppercut tracks.
Range from jab as a range ruler, not a point swipe matters before you ever throw the hook. Too far and the uppercut is a prayer.
Use it to punish lazy outside slips
Some opponents slip outside every rear hand out of habit. Make the uppercut the tax on that habit. When they start slipping less predictably, you have already won the chess move.
In sparring, agree on controlled power until both partners show clean slips and covers. Timing first, then snap. A short rule you can say in one breath beats a flowery combo chart you abandon when tired.
Revisit after camp changes. New sparring partners slip differently. Tighten only what failed on film.
Keep the check-hook path available too when they rush instead of slip; see check hook after slip that recovers center line fast for the rush version of the same pocket discipline.
FAQ
When does the uppercut fire?
As their head clears outside the rear hook, not after you have already reset low.
Why short uppercuts?
Long arcs are slow, easy to see, and leave you open.
What if they slip inside?
Skip the uppercut. Exit, body shot, or check hook instead.
Should the hook be hard?
Hard enough to force a real slip. Soft hooks get ignored.
How do I drill safely?
Known rhythm, one uppercut per wave, headgear if needed, clear stop words.
What if I miss?
Cover and reset center. Do not throw a second wild uppercut.
