Melissa "Mack 10" McMorrow is a Brazilian American from San Jose, California. She now lives and trains in San Francisco, California. Melissa is about to make her pro debut after a successful amateur career.

She began boxing in March of 2005 and had her first match after only three months of training. She fought locally whenever she could get a match often moving to different weight classes in order to find opponents.

In March of 2006 Melissa fought in the flyweight division of Northern California Golden Gloves wining the tournament against Amber Howard of San Jose making her the 2006 Northern California Golden Gloves flyweight champion.

Later that month, she competed in the San Francisco Golden Gloves. She won her semi-final bout against Amber Howard by an easy margin, but lost by a close decision to Ava Knight of Chico, California in the final.

In July of 2006, Melissa fought in the National Golden Gloves in Ft. Lauderdale, Florida. She won by TKO in the second round to Aileen Viera making her the 2006 National Golden Gloves Flyweight Champion. By the end of the year Melissa was ranked 3rd in the nation by USA boxing.

In March of 2007, Melissa fought in the San Francisco USA Road to the Nationals tournament in San Francisco. With no opponents in her weight class, she agreed to fight at 114 lbs. She defeated Courtney Ogawa of Redwood City by a unanimous decision for the San Francisco USA Jr. Bantamweight Championship.

Later that month, Melissa weighed in for the 2007 Northern California Golden Gloves in the flyweight division. With no opponent will to fight at 106, 110, or 114 lbs., Melissa won the 2007 Northern California Golden Gloves Flyweight Title by walkover.

In March of 2007, Melissa competed in the USA Nationals in the jr. flyweight division. She lost in the finals 23-22 in a controversial decision to former national champion Marlen Esparza. The silver medal earned her a second place ranking for 2007 by USA Boxing.

Melissa trains 6 days a week at 3rd Street Boxing Gym and Titanium Training Center in San Francisco under the direction of Paul Wade who is to be her manager and trainer upon starting as a pro. Melissa says "Paul is a great trainer. He stresses movement, defense, and creative thinking. Most of all, he is demanding. It's great to find a trainer who demands more from me than I already demand from myself." This is a willing combination because Melissa is already a very self demanding and persevering athlete. In addition to training in the gym, she runs every morning alternating between long flat runs, hill training, and intense sprint workouts. Her endurance, mental strength, confidence, and dexterity are powerful assets to her boxing skills.

Melissa has always been a top level athlete. She grew up playing soccer and was an All-American in college then moved on to play semi-pro soccer in both the US and Brazil. After playing soccer for 18 years, the disbanding of the Women's United Soccer Association (WUSA), the only women's professional soccer league, left her with nothing left to strive for. She began searching for another competitive outlet. Having always been captivated by boxing, she fell in love with the sport by attending fight parties thrown by a local motorcycle club in Oakland, California. She credits the East Bay Rats, a motorcycle club celebrated because of their boxing events, with the impetus for her pursuit of a boxing career.

Outside of boxing, Melissa works full time for an architecture firm in San Francisco called William Duff Architects where she is pursuing an architecture license. She has an architecture degree from Carnegie Mellon University. William Duff Architects has designed a number of retail projects related to sports including Footlocker and Puma. "I love designing places and objects that are related to sports" says Melissa. She also has an interest to do graphic design and illustration creating drawings, sports logos, and advertisements.
