This same month on April 20,
2007, at the Star Plaza Theater, in Merrillville, Indiana, Dierdorff (129
an upset when she beat seasoned veteran Mia St.John (136½ lbs). Dierdorff won by a six-round split decision (judges scores 59-55 (St. John) ,
59-55, 58-56 (Dierdorff). Dierdorff came out very aggressively in the early rounds,
while St. John whose left eye was nearly swollen shut, finished the fight
to WBAN correspondent Juan C. Allyon, "Whatever
illusions Rosales-St. John harbored going in, they were jarred loose with a
booming right to the head in round one. The blow stopped St.John in her
tracks and caused her to do a slight stutter step. The war was on. Both had
their moments, as they mauled, slugged and roughed each other up non-stop
for six rounds. It wasn’t so much a boxing match, but a primeval brawl with
pink gloves on. Dierdorff crowded and threw the full weight of her body
behind virtually every swing, winging hurtful blows to body and head.
Rosales-St.John slugged back fiercely, catching her more aggressive foe with
rights coming in and combinations in close. There was a lot of grappling in
close and a little hitting and holding on her part. Yet, for all her
experience, she couldn’t quite offset her younger tormentor’s raw aggression
and power. Dierdorff wasn’t intimidated and, at times, manhandled Rosales-St.John
when pinned on the ropes, forcibly grabbing and turning her back to the
ropes. She was just that strong and energetic. And, she was beating Rosales-St.John
up. In the fourth, Rosales-St. John fell on her backside from what appeared
to be a punch landed while she was off balance and squared-up. Referee Kurt
Spivey ruled it a slip. Going into the sixth and final round, St.John
appeared behind in points. Gathering herself up, she repeatedly backed
Dierdorff to the ropes and battered with both fists. Dierdorff fought back
hard, but fighting in her first six-rounder, she seemed to tire and was
clearly edged in this round." Dierdorff was a late replacement for Rita Figueroa who was
injured during training. Dierdorff earned an
honorable mention with WBAN as fighter of the month for this win.
"I took that fight on four
days notice after Rita Figueroa got hurt and had to drop out", Brooke
WBAN correspondent Bernie McCoy. "I didn't have time to properly train and
make weight but I still thought I won easily. There was a lot of talk about
how I got a 'hometown' decision. The fact is I live in Illinois and the
fight was in Indiana, and the truth is that Mia was the attraction that
night, she was the 'house' fighter. She even came into the ring wearing the
promoter's logo ... I won that first bout straight up."

On September 21, 2007, at the
Meadowbrook Music Festival, in Rochester Hills, Michigan, Border City Boxing
Club's Jeannine "Heartless" Garside TKO'd
Dierdorff at 1:10 in the sixth round, of a scheduled six round bout. Both fighters
carried undefeated records into the ring, and there was no love lost between
the two from the opening bell. Garside knocked Dierdorff down three times,
before referee Frank Garza called a halt to the bout in round six. In one news article they stated,
"Garside came out aggressively, sending Dierdorff down for a flash knockdown
at the end of the first round with an extended flurry along the ropes.
Showing her toughness, Dierdorff recovered well and the next five rounds
were a festival of power punching that had the crowd roaring at every turn
of momentum. Back and forth the two women went, first one taking the
initiative and then the other. Dierdorff's corner threw in the towel in the
6th and final round after Dierdorff was knocked down again." The
fight was not without controversy after Garside punched at Dierdorff after Dierdorff went down against
the ropes in the first round, risking a disqualification. Dierdorff recovered
well and her accurate punching made a fight of it until Garside got the upper
hand in the final round. Garside's record
improved to 7-0-1 (3 KOs), while Dierdorff's
fell to 4-1-1 (3 KOs). (For more of Dan Graschuk's photos of this

31, 2008 at the Utopia Paradise Theater in the Bronx, New York, former IWBF
world champion Alicia "Slick" Ashley
(121 lbs) of Westbury, New York lived up to her
nickname with a smooth eight round unanimous (79-73,78-74,80-72) decision over a game Dierdorff
(120 lbs) employing early round, ring-wide, movement and late round,
pinpoint punching, WBAN correspondent Bernie McCoy
that ""Slick" is not only Ashley's
nickname, it's an accurate description of her silky smooth moves in the
ring. That graceful aspect of Ashley's repertoire was on full display over
eight rounds against a game, determined Brooke Dierdorff, who defines the
description, "she comes to fight." Dierdorff took the fight to Ashley early
in the bout, but Ashley's movement was the defining factor for the first
couple of rounds. In the middle rounds, Ashley started to land her jab
frequently and had Dierdorff bleeding from the nose. Dierdorff's best round
was the fifth when she managed to catch Ashley with a couple of hard shots,
but the veteran fighter regrouped, got back into her rhythm and clinched the
bout with big seventh and eighth rounds, when Ashley landed her hardest
punches of the bout." The win
gave the veteran Ashley the vacant NABF super bantamweight crown and improved her record to 14-7-1.

On March 27, 2008, at the Main
Street Armory, in Rochester, New York, featherweight Ela Nunez (126 lbs) TKO’d Dierdorff
(127 lbs) at 1:05 in the fifth round of a scheduled eight rounder.
Nunez improved to 6-3 (2 KO's) with the win.
20, 2008, at the Mile High Events Center in Commerce City, Colorado,
undefeated Jennifer Barber (125 lbs) from
Northridge, California won an eight-round unanimous (80-71,80-71,79-72) decision over Dierdorff
(124 lbs) for the vacant NABF featherweight title.
According to Eric Duran of Rocky Mountain Boxing,
the opening round, Dierdorff ... came out with the
strategy of trying to bully Barber. It worked for most of the first
round as Dierdorff banged away at the body when both fighters were
clinched. In the 2nd
round, it was more of the same, Dierdorff banging away in the clinch.
skills were on display with some nice combinations, but it was the
Dierdorff that won her the round on my card. Round 3 was all Barber as
picked up her pace and displayed some very good boxing abilities. In
minute of the round, Barber opened up a cut over the left eye of
a counter right hand. Barber ends the round with a straight right that
the knees of Dierdorff.
In Round 4, Barber opened up her arsenal of weapons, unleashing furious
combinations onto Dierdorff. Midway through the round, Barber catches Dierdorff
with a straight right hand that wobbles her. Round 5 started off with back and
forth action as both fighters are putting in work. Yet it's Barber who weathers
the storm and dominates the remainder of the round with lead left hooks and lead
right hands. Round 6 was slow as both fighters look to rest before the
championship rounds of this 8 round contest. Barber establishes her herself in
the round with a straight right hand that hurts the fading Dierdorff. Round 7
was all Barber as a counter left hook flattens Dierdorff in the opening minute
of the round. A nice 'short shot' hook. From there on out, Barber continues to
catch Dierdorff with flush shots as the blood from the previous cut over
Dierdorff's eye continues to flow. After 8 rounds of beautiful boxing, Barber
slows her pace and coasts to easy victory, keeping Dierdorff at bay with a
stinging jab." Barber improved her pro record to 8-0 (4 KO's)
with this win.
St.John and Dierdorff before their rematch
On April 4, 2009 at Ciudad Victoria in
Tamaulipas, Mexico, Brooke Dierdorff (131 lbs) won an
eight round unanimous (76-77,78-76,77-75) decision over Mia St. John (130
lbs) for the WBC International lightweight title.
According to James
Blears at Boxingscene.com, "Mia
who'd lost in their first encounter in April 2007 due to a
telephone booth style brawl, tried to use her longer reach this time
around to box, but Brooke was again successful with her rough
tactics which weren't elegant, but they proved effective. Mia started
well boxing intelligently, but as the fight wore on there were more and
more clinches. Mia whose left cheek was scuffed raw fought back with
courage, cuffing Brooke in clinches with some short rights and going to
the body. But Brooke's work rate was higher and she was giving
marginally more than she was taking although there were not too many
clean connecting punches. Mia caught Brooke charging in with a peach of
a long arching right hook at the beginning of the eighth and final
round. More of this marksmanship would have won her the fight,
but Brooke had smothered her style. To their credit, both ladies showed
their class with great sportswomanship following the final bell. And
the crowd applauded Brooke for a hard fought win". St.John fell to 45-10-2 (18 KO's) with the loss.
On January 29 2010 Brooke married her trainer/manager Chris Milbrook.

lbs) of Gary, Indiana.

controlled the first four rounds with several hard charges that repeatedly
pinned McGee against the ropes. McGee, however, opened the fifth round with a
relentless attack and ended the sixth by drawing blood from Dierdorff's nose.
Still, McGee's late emergence wasn't enough in the end." The
loss dropped McGee to 17-1 (10 KO's).
