This same month on April 20, 2007, at the Star Plaza Theater, in Merrillville, Indiana, Dierdorff (129 lbs) pulled an upset when she beat seasoned veteran Mia St.John (136 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 strong. According 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. [ Video-youtube]

"I took that fight on four days notice after Rita Figueroa got hurt and had to drop out", Brooke later told 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 fight, see MPEG/Photo Gallery #447 on the WBAN Records Member Site).

On January 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 wrote 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. [Video - You Tube]

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.

On September 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, "In 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. Barber's skills were on display with some nice combinations, but it was the pressure of Dierdorff that won her the round on my card. Round 3 was all Barber as she picked up her pace and displayed some very good boxing abilities. In the first minute of the round, Barber opened up a cut over the left eye of Dierdorff with a counter right hand. Barber ends the round with a straight right that buckles 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.

On February 26, 2010 at the Hammond Civic Center in Hammond, Indiana, Brooke (133 lbs) won a six-round unanimous (58-56,58-56,58-56) decision over previously unbeaten local favorite Mary McGee (136 lbs) of Gary, Indiana.  According to NW Indiana Times correspondent Nate Ulrich, "Dierdorff 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).

The win over McGee earned Dierdorff WBAN's Fighter of the Month award for March 2010.

On July 8, 2010 at the Convention Center in Winnipeg, Manitoba, Canada, Olivia Gerula (127 lbs) of Winnipeg won a ten-round unanimous (98-92, 98-92, 97-93) decision over Brooke (127 lbs) defending her WBC Junior Lightweight title.  Gerula started slowly but came on strong in the later rounds after bloodying Dierdorff's nose in the fifth round.   Gerula improved to 13-10-2 (4 KOs) while Dierdorff fell to 6-5-1 (3 KO's).

On March 25 2011 at the Hanging Gardens in River Grove, Illinois, USA, Brooke Dierdorff (132 lbs) fought to a four-round draw eith Ashleigh Curry (133 lbs) of St, Joseph, Missouri  who moved her record to 3-6-2 (1 KO).  Dierdorff was now 6-5-2 (3 KO's).
