Before: Garner's putting the pieces together - finally solving Cat Bell, Ryan under wraps, Theron at bay - many are calling Jen the most dominant all round fighter in the business. Casta one of the few remaining sore spots for Jennifer, although Garner enters a comfy favourite for this defence.

"You can't sleep on Casta," says Garner in prefight. "She's got Theron's will, Ryan's punch, a little of Bell's savvy - she's no picnic. I'll ride my quickness to victory, but I'm not taking her for granted. I've trained as hard for Laetitia Casta as I have for anyone."

During R1: Garner sets the pace, jabbing briskly, stepping crisp to the left. Both girls with right hands up, eyes bright with concentration, but it's Jen doing the scoring, touching Laetitia all over the educated left hand. Final minute - thunderclap Casta right over Jen's extended left and GARNER GOES DOWN! Sudden power outage - Garner on her butt, shaking her head, she's up quick, almost pitches onto her face, steadies herself at the ropes. Casta salts away the round with a systematic drubbing, pawing at Jennifer's guard the jab, then thump-thumping to waist right/left.

R2: Garner classy early - script hasn't changed, she's using her legs, getting off first, circling her foe. Casta nice and relaxed, dipping slightly to the right as Jen jabs, dragging her front foot as she slides back and to the left, inducing Garner forward. Midway through, Garner misses a slashing right over top, Casta slings a walloping left against the ribs, comes over top the cracking right hand - big head swivel and stomping in fence post holes for Jennifer. Casta staying focused, jabbing her girl to ropes, then leaning in to drag a big right hand hard to the ribs - thudding connect has ringsiders gasping as Jennifer folds forward hurt. Garner gutty to the bell, staying close to Laetitia, chewing up the model's breadbasket on the inside with shoeshining fury - Casta's power rewarded with points.

R3: Third straight round in a row - Garner cruising, using her boxing, outclassing Casta, only to have everything turn around off a clean right hand on the chin. Final minute - Jennifer put wobbly butt by that sneaky, semi-screend French Cross - Jenny to the ropes and Casta piles on. French girl brawny, palming Garner's shoulders, dipping down to reef at the midsection. Garner taking a good shot down there, but not answering back - she's stiffening up from the punishment.

R4: ANOTHER clanging right hand from Casta - this time off a little fade step to the right - whistling hesitation cross against the teeth has Jennifer reeling. As she has all night - Laetitia consolidates a bomb with dutiful body work - very professional, systematic attack slowly dismantling the champion. Garner standing her ground late - she's still the quicker-mitted girl on the inside, taking what she wants of Laetitia's belly and breasts with chopping shots.

R5: Even tactical round to the final minute - Casta answering Garner's speed with a well timed jab to the chest and down the stretch - Laetitia lights Jenny up yet again with that blistering right hand. Casta just extending in and down, clapping Garner's head to the side - loose, relaxed delivery somehow catching Jenny again and again. Loping follow up from Casta, she dips and sweeps the right wide to the ribcage - hollow thud sends Garner groaning to the ropes where she sets up head in hands. Laetitia just pushing her jab against the guard, occupying Jenny, then whump-thump to the body right/left - leaving nothing to chance. Paralysis spreading through Jen's body - Casta's checking the champ's chin, then banging her powerplant each and every round.

R6: Garner stops the insanity, but it's a close, nip and tuck round. Jenny stepping left, scissoring her jab, Casta looking for right hands over the stick but can't pull the trigger. Laetitia jabbing well as she has all night - she's not as fast as Jen, but she's fundamentally sound, jabbing at the right times, taking some options away from the champ.

R7: Garner keeps at her foe, now working crisp combinations off the jab, then hopping away to the left, turning Laetitia midring. Casta getting her head bounced hard for the first time in the fight - she's squaring up but not getting off - Jenny's tattooing her. Down the stretch, Garner jabs, steps left, feints the jab, pokes a straight right hand and jerks the rigid left uppercut to the chin - LAETITIA GOES DOWN! Sigh of relief from HISC suits as Garner gets it going, dumping Casta in a bewildered heap at last.

R8: Garner keeps it going - a hard right hand stuns Laetitia, has her covering up - sturdy ribwork has the French girl backing to the ropes for the first time. Jenny getting her shoulder into Laetitia's chest and levering her up - Garner getting big-girl to bang her foe's body, pick her up with right uppercuts on the inside. Casta soaking, but durable - she's taking a good shot, blocking others as she moves her head, gives up a shutout.

R9: Casta catches a second wind. With Garner chipping away at her lead, Laetitia lays down a golden ninth - jabbing, moving, running Jen into the right hand, then clinching. Garner gobbled up in French girl's slick punch n' clutch - Laetitia playing for time, knows Jen's got to press and take chances. Casta wrapping up tight, walking her girl to ropes for breaks, slowing this thing down.

R10: Casta jabbing to the body, sliding back, then clinching - Garner frustrated, writhing in the clinch and the holding's making her complacent. Midway through, Jennifer burrowing in behind her jab, expecting the tie-up, but Laetitia unpacks that vicious right hand instead, beating Garner to the cross and DROPPING JEN TO ONE KNEE! Defining moment of the fight as Laetitia makes eye contact - champion shabby, reeling, on the canvas, looks up at a girl who's had her number tonight. Casta workmanlike after 8, bodying up, walking Jen to the ropes, palming her to stabilize and going methodically to the waistline with sumptuous haymakers. Garner stiff and achy, stooped forward, just accepting the punishment on her blocky abs as Laetitia bangs out the shutout 10th. Comes back a workmanlike upset UD10 for the winner and NEW lightweight champ - Laetitia Casta!

After: Lightweight gold proving hard to hold - odds-on favourite Jennifer Garner runs afoul of Laetitia's clever right hands - American does well to finish this thing on her feet.

"I thought I'd turned it around," mumbles a badly worn Jen in postfight, "I had her down, I was getting to her. I don't think I've ever been hit that hard, that consistently - she really got her power stroke over tonight in a way I never thought she could."

Casta equally complimentary, "Jennifer Garner can box all night long, but what people don't realize is she has the heart of a lion! The right hand I hit her with in the first would have stopped Jeri Ryan. Theron would have given out after just a few rounds of the punishment I was able to bring to bear - but this girl just kept going. My chapeau is off to a very brave fighter and great champion
