BEFORE: Plenty of pre-fight squabbling, bickering, shouting, pushing, pouting, scowling between these two: Cassie refusing to back down from Song's aggression, nor is the blonde offering the same sort of respect she has afforded Hayden in this period. "I'm pumped," says Guest Commentator Hayden Panettiere ringside. "This is a great matchup between two terrific, equally matched girls with similar backgrounds and influences. Ever since her training film leaked, the buzz on Cassie's been deafening...but I think Brenda's been a bit of a forgotten fighter here. Song holds wins over HISC fighters; she's beaten me in the past, and at one point, she was sort of running wild in the division. Cassie can't compete with Brenda's record, so I'm going with Brenda in this one...by a smidge!" Song in white cashmere crochet bikini; tan UGG boxing boots to midcalf; small white mitts; hair tied off her brow, long and black down her back. Cassie in baby blue cashmere crochet bikini; tan Ugg boxing boots; small white mitts; hair in high ponytail with bangs framing face. Pleasing scowl-down during ring-instructions: both girls impossibly cute when they're angry.

During R1: Cassie at Song with quick, jitterbugging hops - doubling the jab at Brenda's chest, then seeking combos. Brenda sliding/stepping to her left, leaning back on her hips, keeping weight on rear (right) leg. Cassie's dukes're up: Brenda dangling her left, keeping right at her chest. Song supple on her hips - pivoting around grounded left heel while bobbing low/leaning well back - changing levels and trying to time Cassie. Bren doing her scoring off the counter - bringing hooks up off her thigh while pivoting sharply left; feinting, then flashing the straight right off her chest. Cassie blocking/ducking much of this, but she's being pre-empted: Song out-dueling her blonde midring in a tactical first.

R2: Cassie hopping in her stance, spitting jabs: she knocks at Brenda's chest, then forehead, before coming in hot. Bang-bang combinations from Cassie when she's close - ripping Song to the belly/ribs/chin. Brenda bailing out, spooked. Cassie forcing a lot of inside trading session - little blonde digging furiously at her brunette, working the body: Song sliding off to either side, fitting Cassie for sudden right uppercuts or left hooks in counter. Cassie's pressure prevails: Song hard to hit cleanly as she's dipping and rolling, but Scerbo's coming forward, imposing will through 2.

R3: Song walks Cassie into a glorious lead left uppercut at the open - pivoting round blonde right flank as Cassie's stepping in fence post holes. Moments later, as Cassie's trying to attack...Brenda rolls-right with a blonde right hand - answers back a vicious short right uppercut to chin: gorgeous counter punch straightens Cassie up, brings her heels scooting forward and SCERBO'S ON HER BUTT! Brenda grinning down, batting mitts together: Cassie blinking rapidly, sitting in a puddle of shock and distress. Scerbo beats the count shabby: she covers up peek-a-boo at ropes, 'cause HERE COMES BRENDA! Song scowling, squaring up with plenty of time on the clock: oh how she beats her blonde. Digging pumps at tummy and arms weaken Scerbo's guard, allowing Song to reach in underneath and pry it apart. Song tummying up, bodying Scerbo into ropes, then swiping at her in tight: blonde girl cuffed about both cheeks; chopped in behind both elbows. Cassie distraught, trying to clinch: Song proving able to wrestle with hurting blonde, writhing Cassie back down to ropes, then working her over. Both girls digging right hands while semi-clinching the other in the left hand: Song with top position at the ropes, beats hell out of Scerbo's body in trade. Down the stretch, Cassie reeling: Song mounts an electrifying hup-hup surge of rising lefts and rights against Scerbo's jugs, beating blonde upright to ropes. Savage stuff, designed to break a girl's will: Scerbo gasping, looking ransacked at the bell. LATE HIT, BRENDA SONG! Song with a forget-me-not hook to chops sits a bedazzled Cassie in ropes: seething little brunette pushed away and scolded by angry ref.

R4: Cassie rallies: badly beaten and dominated last round, she recovers her legs, taking the initiative from Song with volume again. Cassie in and out - pumping a stubby jab for entrance, then blitzing Song's body and jaw with swift, jarring rights and lefts in combination. Song smote by hooks and uppercuts, forced to roll her torso and stay defensive. After Cassie's gotten off, she'll pivot quick to her right, shifting angle on Bren, hooking at her from outside the Song left shoulder. Song still having success off the counter - fitting Cassie for clouting single shots - but Scerbo's will prevails in the fourth.

R5: Cassie's early pressure is blunted by clever fade-steps back from Song - blonde lured into little gaps, then countered by crafty brunette. Song shifting weight to front (left) foot as she operates - leaning close to dig short left uppercuts to Cassie's body; hooking her head; pivoting left around her right flank. Scerbo getting the range she wants, but being bamboozled: Song flashing slick, doubled-up left hand technique to touch her blonde up this round. Cassie durable, but really clipped and smote this round: Song lands a high percentage of head shots, and nearly all her body shots in turning battle midring. "I've got Song ahead through 5," Hayden reports cheerfully during the break.

R6: Cassie doubling up her jab - forcing Bren to roll/slip: Cassie leans in on front (left) leg, then lets hands go, drenching Brenda's defences. Cassie deliberately crowding, reaching under Song's arms to tummy up on her: blonde walking brunette to ropes, throwing tuff little left shoulders into her mouth for good measure. Grimy, close-in squirming-and-slugging evolves: Brenda grimacing as she works to push her left hand down inside Cassie's right arm, then dig at Scerbo righty. Scerbo doing much the same - sturdy legs straining, buttocks ringing with the effort of keeping Song pinned down. Brutal, grunting stuff here - all initiated by Scerbo: she's suffering tuff hits, but getting the better of grinding attrition here. Song butt-in-ropes, really smothered and oppressed: Scerbo able to plug right hands to tummy, or jam away at jaw in tight clinches. Sloppy stuff - lots of writhing and squirming as girls wriggle for punching room: ref lets it go since both are working. Bell: Scerbo digs an extra right hand to the pit of Brenda's belly, drawing a woozy "UH!" from Song's parted lips.

R7: Song proves sturdy. Girls box for position in the opening moments - nifty feet jitterbugging and hopping about in wide stances - then both engage, coming in hot off the jab. Song willing to work inside, gritting her teeth as she pushes against Cassie, then pumps her tummy righty. Cassie banging back in kind, writhing against Song for position midring. Brenda jerking a slick little right uppercut through to Scerbo's chin: blonde head routinely jerking up with the contact. Bit by bit, Brenda's able to come forward - occasionally sliding off to the right while pushing on Cassie, messing up blonde's balance even more. Ropes - Song on top: it's Brenda now conducting bruising attrition against all things Cassie. Scerbo frowning, frequently pinned against ropes and suffering as right hands pump her gut: Brenda panting, grunting with the effort of both controlling and hurting her stubborn blonde foe. Bell: Song tucks a late right hand into Scerbo's gut, winning back that gasping "UH!" that Cassie had extracted from Bren last round.

R8: Cassie now uses fade-tactics - hopping back in her stance as Brenda's attacking, disrupting brunette timing. Cass with a nimble left hand: left uppercut to the body; swiping left to the mouth; pivot-right to a spot just off Brenda's right shoulder; extra left uppercut. Song turning, getting touched up: she steps to the attack, only to find Cassie's hopped back out of range and getting off as Brenda stumbles forward. Cassie digging, hopping to either side, punching in combination: serious tattooing results, chipping away at Brenda body and head. Midway through, deft tic-tac-toe has Brenda staggering - she reels away in confusion, eyes rapidly blinking away tears. Cassie hopping forward, then taking that little half-step back: Brenda constantly induced to tip forward into the teeth of Cassie's combos. Punches in bunches - constant heavy clap of Cassie's peppering fists sounding out off Brenda's ribs/face: Song's breaking down. Late the round - stubby right hand chops at Brenda's cheek, turning her face aside. Pair of digging left uppercuts takes Brenda in the gut, sitting her butt-in-ropes. Another peppy right clubs short across Brenda's face: Scerbo leaning into her assault, eyes blazing, face intense. Left uppercut to solar plexus has Song sobbing: short right turns her chin aside...dazed, Brenda spills to her right along the ropes, then clatters to forearms and knees, forehead against canvas as crowd roars to feet. Scerbo chest heaving, backs away to neutral corner: poor Brenda battered, ragged, can't get off her knees. KO8 Cassie Scerbo.

After: Scerbo bellowing out "YES!" hugging herself in exultation as Brenda manages to sit up against ropes, eyes all glassy and hollow. Thrilling back and forth shows class on both sides, but Scerbo just made of sterner stuff, willing herself off the canvas where Song could not. No mercy between Disney class flyweights: once Song's on her feet, Cassie comes forward - scowling little blonde pulling Bren away from her handlers for a parading walks of shame. Hayden pursing lips as Scerbo struts past with captive in tow. Blazing eye contact made between blondes as poor Brenda's limp in the grasp, head lolling, Ugg boots scuffing sadly along on canvas.
