Juan Medina

Juan Medina was born in Laredo, Texas on December 7, 1951. He has resided in Zapata, TX, a small town located about 50 miles south of Laredo.


During his high school years, Juan was the starting quarterback for the Zapata High School Hawks. He began working in the oilfield and learning the trade after attending 2 years of college at Laredo Community College. Juan met his wife Dolores in 1970. They married in 1975 and had four daughters. His daughters graduated from college, married and made Medina a proud grandfather of 10 grandchildren. Juan was introduced to the sport of horse racing by his father in law, Delfino Lozano Jr, in the late 70’s and developed a passion for the sport.

He purchased his first horse and raced in small time races throughout the state of Texas. In 1984 he co-founded Med-Loz Lease Service in Zapata with his brother-in-law, Delfino Lozano III. They worked from the ground up developing the company into one of the Top 500 Hispanic Owned Businesses in the country.

Juan purchased his first ranch in the late 1990’s and is now the proud owner of over 12,000 acres in Zapata and Atascosa County with a Charolais cow calf cattle operation of over 500 head of cattle as well as scientific breeding operations with very high quality white tail deer. Horse racing came back into the picture in 2000 when Juan began buying horses at auctions in Louisiana, Texas, Oklahoma and New Mexico. He won numerous races throughout the state of Texas, Oklahoma, New Mexico and Louisiana.

In 2005 he purchased Baja Jazz and gaining a couple of wins racing at Ruidoso Downs and a win at Manor Downs. Teller Baja a filly out of Teller Cartel and Baja Jazz had winnings of over $500,000 in Grade 1 events. His greatest achievement came when Eagle Jazz (the gelded son of One Dashing Eagle and Baja Jazz) raced his way in the elusive Quarter Horse Triple Crown at Ruidoso Downs in Ruidoso, New Mexico which has only been won once in the history of the three G1 races, by Special Effort in 1981. Eagle Jazz won the first two legs by first winning the $1 million Ruidoso Futurity (G1) in June then winning the $1 million Rainbow Futurity (G1).

Eagle Jazz won his heat by 6 lengths but just missed the qualifying time for the $3 million All American Futurity (G1) by five one-hundredths of a second. Medina plans on continuing his successful racing career. He already has his eye on next year’s Triple Crown with many years to come with offspring out of his prized Baja Jazz.
