Venue: open-air boxing at the Aussie Open main court - ring set up in lieu of nets.

BEFORE: Michelle best known as the sexy hurdler and you tube sensation...

 not to mention SI model (see the new ish!). She's reputed to have worked as a special strength/conditioning consultant to fellow Aussie Anna Torv, but she doesn't just hang around in celebrity camps - she's out there slugging for glory of her own!

"I'm 'chelley Jenneke," Brunette grins in prefight, showcasing her aussie drawl, "and I'm hear to kick some Danish-girl ass!"

Wozniacki ill-amused: former world number 1 WTA star not about to roll over for an "internet bimbo". "The girl's never won anything in her life," Caroline shrugs defensively. "Sure she's a strapping young lass, but I'm one of the strongest girls on tour - I think I can handle what Michelle's bringing!"

Jenneke in fighting green trunks with white sport top; white shoes with ankle-socks; fighting high pony with pretty green ribbon; white mitts. Caroline in orange V neck sport top; orange snug-fit boy leg bottoms with little white belt; white gloves/white shoes with ankle socks; fighting blonde battle braid with strands straying off the hairline.

Ring instructions: Jenneke grinning, doing her little warm up dance right there as ref's talking; Wozniacki smoldering with irritation on the spot.

R1: Girls hop-to midring, frisking one another's tops with jabs, then laying in strong rights/walloping left hooks in a brawny test of will. Wozniacki with the better of it early, driving in righty to chin, backing her girl up, but minute mark: ROBUST, free-swinging rights and lefts wide to head bludgeon Caroline off balance and SEND HER DOWN! Car-car sputtering to all fours...'chelley scampering to neutral corner with her heels kicking herself in the backside en-route, then she stays warm in the corner by doing her dance while Wozniacki's getting a woozy 8! Resume: Michelle frisky as puppies jogging back in, STRAPPING Caroline thickly about the waist right/left/right! Veteran t-baller groaning, pulling brawny brunette into clinches about the head/shoulders...aggressive track-star stays busy, packing right hands into tennis-player gut until ref issues break.

R2: Wozniacki showing ring-smarts - jabbing Michelle; quick-stepping clockwise; timing brunette for short, drifting right hands to chin, then tying up around Jenneke's elbows for break. Michelle wriggling in the grasp, resetting herself dukes-at-mouth in hopes of more free-swinging trade, but Car-car doing a good job denying such terms - touching her girl, tying her up for a safety-first recovery round.

R3: Michelle settles down, punishes Caroline's jugs via competitive jab, shrugging off Wozniacki's jabs in receipt. Willful brunette hopping forward - gleefully trading right hands, then coming back hooks...Caroline forced to back away in the face of young-punching exuberance. Jenneke showing the heart of a body-stalker in spots - walking Car-car down via muscular, strapping right/lefts thick across the gut...Wozniacki grimacing cranky when smote, often looking to tie up rather than answer thereafter.

R4: Woz punching jabs to Michelle's grinning mouth, knocking brunette head back; fitting 'chelley for short, muscular right crosses with plenty of broad back and strong legs behind them. Jenneke taking a great shot, but giving up a lot of chin in the exchanges...Caroline able to hop forward, tie up, body her girl to ropes for breaks while salting away the points. Bit of chippiness in the clinches - ref warning Woz for throwing her shoulder into tits and mouth before breaks.

R5: Michelle swinging away care-free, connecting on wide, walloping lefts and rights to jaw...Caroline wobbles to her right, turning her back in confusion, blinking with hurt. Jenneke attacking from 3/4s rear off the Wozniacki left hip - brunette's left arm threads underneath Wozniacki's left, delivering jerking little uppercuts from in close, shutting off power to Caroline's legs and BLONDE GIRL DOWN! Awkward bullying from the odd angle puts tennis girl on hands-and-haunches...fun-loving romping jog to corner for Michelle - her heels kicking her own backside, then more of the hip-action dancing until Woz gets herself together. Woz rocked, but rallying...she jabs herself off the ropes, engages Michelle in clockwise turning battle midring, tying frisky brunette up after hot-slugging exchanges, forcing ref to push strong-bodied lasses apart.

R6: Wozniacki's been getting that sneaky, dependable short right hand off the shoulder onto Michelle's chin all night...she finally hurts Jenneke with it in minute 1. Jenneke wobbly-butt, frowning and distressed for the first time...she stoops forward behind rigid earmuff as Wozniacki goes to work. Caroline rotating to her right, DIGGING left/rights to sturdy brunette waistline, whacking away in thick behind or below either elbow. Woz testing the guard via scraping little uppercuts - mostly just to keep 'chelley covered up: it's body Caroline craves, and body she's taking through 6. Bell: Michelle looking disheveled, grumpy...WOZNIACKI DOES 'CHELLEY'S WARM-UP DANCE ON THE SPOT JUST TO TAUNT! Ref knows provocation when he sees it - moves in to separate strong young vixens.

R7: Short right hand: JENNEKE'S ON HER BACK! Crashing blast in close - Woz bending her back into a chopping chin-shot...Michelle's flat out, picking her head up off canvas all "wha' hoppen?" Wozniacki bellowing ferociously into crowd en route to neutral corner: Michelle's turn to scrape herself up out of the rubble. Leads to siege-of-'chelle at ropes - brunette slouching forward in earmuff, giving away firm young body on the cheap as Woz crowds close to work. Caroline just a-TANNING those hips, that waist - thick, thumping left/rights bouncing off Aussie meat - then Woz resets with a shoving left elbow propped against Michelle's raised guard. Give her credit - Jenneke hurt and sluggish, but answering back late - fitting a short right uppercut to jugs/turning over short-shrugging left hooks to chin in tight, punching strong off the ropes at bell.

R8: Michelle outworks Caroline as girls battle midring. Jenneke tireless - stooping forward all grinning, weaving her torso side to side, then slugging up from the crouch. Caroline sullen behind good strong earmuff - turning on the spot, blocking shots, but unable to find 'chelle in receipt. Aussie really salts it away late, paralyzing Caroline with a ripping assortment of rights and lefts strapped thick to waist...HUGE smile on Jenneke's face as she's prancing back to corner for break.

R9: Caroline grumpy, frowning, but cagey - playing jab-and-hold, hook-and-hold as Michelle's seeking brawling exchanges. Blonde girl picking her spots well - touching and tying up before brunette gets off. Strong-bodied girls tumbling along ropes in brawny embraces - both warned for holding and hitting and general rough-house as things get sloppy late.

R10: Girls trade walloping body shots as one covers up earmuff while the other straps the waistline...crowd-rousing stuff as these punches land like baseball bats smacking wet clay. Bruising brutality...fighters meandering counter-clockwise, beating each other hellish blows to torso...down the stretch, 'chelley comes off the tummy via short left uppercut, picking up Caroline's chin and unhinging her legs! Blonde girl ashen-faced, staring as she stumbles into ropes all wobbly-butt and forlorn...she tries to cover up, but Michelle's in there slammin' away to glory, beating apart the guard; battering Caroline about the head! Wozniacki bludgeoned - her hands drop to her waist; body relaxes into ropes as head pitches and yaws with the impact of Jenneke's riotous slugging and THE REF STEPS IN! Wozniacki out on her feet with just seconds left - KO10 Michelle Jenneke!

AFter: Jenneke punched lumpy herself, but all grinning and wriggly in postfight. "I stopped Caroline Wozniacki!" Jenneke gushes un-necessarily: all the world can see groggy Caroline getting smelling salts on her stool. "It's such a thrill to beat one of the best tennis girls, and I know I can beat them all! Slugging's what I love - I just get into rhythm and I feel like no woman can stand against me!"
