This week on In It To Win It Sports Broadcasting, I am including a special feature on myself, and my own athletic journey. So, hello my name is Antonia Kostoff and I am currently 22 years old. At the moment I am earning my second Masters Degree in Leadership at Ottawa University Arizona. I graduated in 2024 with my Bachelors of Arts in Communication Studies, and my Masters of Arts in Human Resource Studies in 2025. Currently I also am one of the co captains of the Women’s Tennis Program at Ottawa University Arizona. I am originally from Orange County California, and first started playing tennis when I was just five years old. I grew up training and competing in tournaments all around the so-cal area. Some of my biggest achievements would be, winning and reaching the finals in several USTA tournaments in juniors, El Toro High School Women’s Tennis Team MVP for all four years, Doubles Sea View League Finalist 2018, Singles Sea View League Finalist 2019, Singles Sea View League Finalist 2020, CIF Championships Team Finalist 2019, and GSAC Conference League Champions 2022. Some of my accomplishments off the court include, being El Toro High School Female Athlete Of The Year recipient 2021, creator and founder of In It To Win It Sports Broadcasting, I was a Girl Scout of thirteen years and was able to earn my Bronze Award, El Toro High School Excellence Award - Journalism Recipient 2019, and Ottawa University Arizona Scholar Athlete 2021 & 2024. I have always been someone who is very motivated to always stay super busy and loves having a fully packed day. In my free time I work part time as an assistant wedding coordinator, spend time growing my website, reading, baking, and spending time with my close family and boyfriend. Some of my biggest supporters along my athletic journey have been my parents, grandparents, sister, and my boyfriend. Each and everyone of them have supported me, inspired me, and pushed me to be the absolute best tennis player and person I can possibly be. They continue to inspire me everyday and I am simply just so forever grateful for their endless support. Another important pillar in my life is my journey growing in my faith and my relationship with God. This past year I have been able to grow as a person, as a tennis player, and simply shift my focus on becoming the person I want to be, and following God’s path for me. Currently I am officially entering my last season of college tennis. This season I am also one of the co captains, and my goals are to be a great leader and role model for my team, support my teammates every single day, and continue to work as hard as I can in achieving my full potential as a player. I am extremely eager for this upcoming season, to continue growing as a player and leading my teammates each and every day! Lets go OUAZ! Fangs Out!
