Martha Claussen, Denis Blake, John Hernandez, Jennifer Hancock, Jonathan Horowitz and Jose Contreras were selected as representatives by AQHA. The major goals of the Wrangler Q-Racing Aces program are to promote the sport, provide fan education services and help to develop new fan bases.

Dennis BlakeDenis Blake

Born: Chatham, NJ
Current residence: Round Rock, TX

Denis Blake has worked in the horse racing industry for 20 years since taking his first job as a teller at Canterbury Downs (now Canterbury Park) near Minneapolis, Minnesota. During his time there, he worked his way up to Simulcast Coordinator and Mutuels Manager while also writing for Daily Racing Form and creating the track’s morning line.

Blake then served as Racing Information Manager for the American Quarter Horse Association in Amarillo, Texas. Shortly thereafter, he moved over to work for the American Quarter Horse Racing Journal as a Field Editor.

Staying in the Lone Star State, Blake then took a position with the Texas Thoroughbred Association in Austin as Website Director and Editor ofThe Texas Thoroughbred magazine. He travels to racetracks across the country for the Q-Racing Aces as a handicapper and fan education specialist.

He currently lives just outside of Austin, where he does freelance work for various magazines and horse organizations, including AQHA, Racing Quarterly magazine, the Texas Thoroughbred Association, The Horsemen’s Journal and Thoroughbred Times.

An avid handicapper of both breeds, Blake has owned numerous racehorses over the years.

Martha ClaussenMartha Claussen

Born: Buffalo, NY
Current residence: Houston, TX

Martha Claussen has been involved in the racing industry since 1997 when she joined Sam Houston Race Park as publicity director. She was responsible for all racing information for American Quarter Horse and Thoroughbred meetings as well as publicity for the racetrack’s numerous promotions and special events.

In addition to writing press releases and interviewing the winning connections on television following each stakes race, Claussen was one of the track's handicappers and responsible for developing fan education programs and handicapping contests.

In 2007, Claussen entered the world of professional journalism, as the racing writer for the Houston Chronicle as well as a contributing writer for the Texas Thoroughbred Magazine and SureBet Racing News. She was part of the media relations team for the 2009 Bank of America Challenge Championships at Los Alamitos Race Course. Claussen serves as the coordinator of the Q-Racing Aces, a new fan education initiative created by the American Quarter Horse Association (AQHA).

Claussen, who graduated from the University of Miami in 1975, was affiliated with International Management Group (IMG) for ten years, managing tennis tournaments. She is quick to acknowledge that working with jockeys is much more enjoyable than with the stars of the men’s and women’s professional tennis tour.

The native of Buffalo, New York has been a lifelong racing fan since watching her first race at Fort Erie, Ontario.

Jogn HernandezJohn Hernandez

Born: San Diego, CA 
Current residence: Des Moines, IA

John Hernandez is a veteran of three decades in the racing and broadcasting industries. Since joining the media staff at Hollywood Park in the Fall of 1981, he has served in various capacities at Hollypark, Santa Anita, Del Mar, and —now— Prairie Meadows in Iowa, where he fills the role of paddock commentator and handicapper.

Over the years, John has hosted racing radio shows on different Southern California outlets including the legendary XTRA Sports 690 in San Diego and new media web streamer World Talk Radio.

In early 2010, John moved from California to Central Iowa to take over as the main on-camera talent at Prairie Meadows. Their 2010 season included the track’s first-ever standalone quarter horse schedule, which included an appearance by the talented Iowa-owned Spit Curl Diva.

Before deciding to concentrate solely on horse racing, John worked as a local television sports anchor/reporter. During his stay at KTUU-TV in Anchorage, AK in the 1980s, he was the person that first gave Sarah Palin the opportunity to work on television.

Jennifer HancockJennifer Hancock

Born: Houston, Texas
Current Residence: Liberty Hill, Texas

Bitten by the “horse bug” at an early age, Jennifer K. Hancock grew up showing American Quarter Horses in Texas and competed on the Texas A&M University horse judging team while earning degrees in animal science and ag journalism. While at A&M, she worked as a racehorse groom and parlayed her racehorse experience into a job at Sam Houston Race Park, where she was the media relations coordinator and press box manger. During her time at Sam Houston, she wrote press releases and assisted with fan education activities.

An AQHA life member, Hancock joined the staff of the American Quarter Horse Association in 2001 as field editor of The American Quarter Horse Racing Journal, and she traveled the country covering America’s fastest athletes. During her time at AQHA, she was promoted to editor of The American Quarter Horse Racing Journal and eventually director of marketing.

An avid horseracing fan, Hancock never passed up an opportunity to go to the races and continues to handicap using bloodline knowledge she acquired before being of legal betting age. According to Hancock, life doesn’t get much better than watching the horses walk through the fog at Los Alamitos to be saddled for the Champion of Champions or watching millionaire hopefuls prep in the first sunlight at Ruidoso Downs on cool mountain mornings.

jonathan horowitzJonathan Horowitz

Born: Los Angeles, CA
Current residence: Denver, CO 

Jonathan Horowitz became the youngest person ever to announce a horse race in the United States when he called the American Quarter Horse Youth Association Stakes at the 1999 Challenge Championships at Los Alamitos Race Course in California.  He has gone on to announce at 23 racetracks in the United States and Great Britain.  Horowitz is currently the announcer at Arapahoe Park outside Denver where he also produces and hosts the “Gates Open at Arapahoe Park” feature television show on Altitude Sports & Entertainment.  In addition, he heads the social media and media relations for the track. 

Horowitz began learning how to ride on former racehorses in 2015 and now competes in and announces at horse shows, sometimes on the same day.  Horowitz has also announced baseball, basketball, boxing, football, gymnastics, lacrosse, soccer, and volleyball as both a play-by-play and public address announcer. 

Horowitz holds a master’s degree in kinesiology specializing in sports business and statistics from the University of Maryland, College Park.  In addition to announcing, he has worked for the Publishing Office at the Library of Congress in Washington, D.C. where he was a co-author for the book Football Nation about 400 years of history of football in American life.  At the Library of Congress, he also authored The One and Only: A Sports Quiz Deck of Definitive Games, Teams, Players, and Events, wrote sections of a book entitled Presidential Campaign Posters, and edited Perspectives on the Hebraic Book.

Praise for the Aces:

"I think the program is very helpful. At Prairie Meadows the Aces were set up by the saddling paddock, which was a good place to be. They were helpful in answering questions and adding much more to the evening of racing. Some people are embarrassed to go to the window and place a bet. If the program can give a fan increased knowledge so they are comfortable to make a bet and win a few bucks, I see that as a benefit to our industry."

-Butch Hammer, Iowa Quarter Horse Association

"Quarter Horse racing is something brand new to many of our fans at Fort Erie Race Track so having a Q-Racing Ace join us for opening day was an absolute must have. They explained Quarter Horse racing in such a simple way that it was easy for new handicappers to learn and feel comfortable in making a wager. Fans felt that they could approach Martha and get the answers that they needed in order to play the races.”

-Elissa Blowe, Fort Erie Race Track

"A great program that is much needed. Racing has far too long been lax on educating new fans to the sport." - Marilyn Toney, Player Development/Fan Education Manager, Remington Park 

"I just wanted to thank Aces Denis Blake and Jen Perkins for the time they spent with my wife and I at Canterbury Park for the Handicapping Quarter Horses Seminar. I was so excited when Canterbury e-mailed me about the seminar, and to be able to learn from the two of you was great! My wife, who I thought was just coming along for the ride, really enjoyed it and felt like she really learned what to look for. In 2009, I really started to enjoy the QH races and paid a lot of attention to Canterbury and Prairie Meadows, but now I have a whole new level of interest thanks to the Aces program. … We have been attending races at Canterbury for about seven or eight years, and have been to even their biggest days like the Claiming Crown, but last Saturday was the most enjoyable time we have ever had at the racetrack! It's not going to be easy to try and be the next Les Onaka, but thanks to the time you spent with me last weekend, I definitely have a desire to learn more and focus most of my time as a horseplayer on the Quarter Horses! Thanks again!" -Scott and Kari Raymond, Fans and Handicappers 

"Saturday, September 24 (2011) was a tremendous day at Fair Grounds!  The crowd was big, the weather was great and our LQHBA Sale Futurity was a very exciting race.  Seeing the Q-Racing Aces in the paddock every race made the day that much better. Martha Claussen picked 7 winners and the fans were betting her picks and cashing some nice tickets!" -Tony Patterson, Louisiana Quarter Horse Breeders Association

"John did an excellent job representing both the AQHA and Quarter Horse racing. He was very attentive to the fans at our facility and was very thorough in his interviewing and handicapping skills. He was also very adaptable to our program and was very willing to jump in and assist all throughout the day. We really appreciate his assistance and hope that he enjoyed his visit to our facility. We’d love to have him back again in 2012 for our next Quarter Horse Day. The entire afternoon was a success and we were very pleased with all activities for our first ever all-Quarter Horse racing day." -Tammy Knox, Hoosier Park Dir. Race Marketing Affairs
