Assistant Coach
Hi, my name is Keegan Anderson, I am the assistant baseball coach here at LASA. I have lived in Austin my entire life and attended LASA high school from 2012-2016. After that I attended St. Edwards University where I majored in Sports Management. Following undergrad I decided to pursue a career in education in hopes to someday be an athletic program administrator, and I am now a Science teacher at Martin Middle School. I have played baseball since I was 5, including all 4 years in high school as a Jag. I didn’t play college ball, but never stopped playing thanks to local men's leagues - I am a LH pitcher/outfielder.
Like many LASA baseball players, I am a product of Oak Hill Youth Sports Association. I have spent many years there as a player, volunteer, grounds crew member, umpire, coach, and am now a commissioner there. In my time at Oak Hill, I head coached two 14U championship teams - one in the spring and one in the summer, and I am excited to continue to develop my coaching abilities and do everything in my power to help develop the Raptors baseball program.
Outside of work I enjoy hanging out with friends and family, spending time with my girlfriend, playing video games, watching comic book movies, and of course keeping up with the MLB season. My favorite baseball team is the Washington Nationals and my favorite baseball movies are the Bad News Bears, Moneyball, and Major League. Looking forward to a great season!

Hello everyone! I consider it an honor and a privilege to be the head coach of the LASA Raptors baseball program. I have three small children: Callen, Carley, and Rowan. I have an intense passion for baseball and still play today with my friends from high school in a local men's league. I played independent professional baseball for parts of two seasons. Collegiately, I played for Texas A&M University - Corpus Christi by way of Laredo JC.
​
I started coaching in Shreveport, LA and was able to help the teams I coached there to two district championships and two state quarterfinal games. Here in Austin, I served as the Varsity Assistant coach at Reagan ECHS, then took over as Head Coach of LBJ High School. In 2021, I moved to the new LASA campus and began building the Raptors Baseball program. I'm excited to be bringing my love for the game and enthusiasm as a mentor to LASA. As the head coach, I hope to help young men grow individually as athletes and students while working together to win on the field as a team.
Looking forward the the bright future ahead of us. Go Raptors!!!

Hello! My name is Calvin Ta, and I am one of the athletic trainers at LASA. I graduated from Saint Edward's University with a Bachelors in Kinesiology in Spring 2019 and from Texas Tech University Health Sciences Center with my Masters in Athletic Training in May 2022. Since then I have worked at Lubbock Sports Medicine Orthopedic Clinic where I was a bracing assistant, a floating medical assistant between 6 physicians, and an outreach athletic trainer to a 2A high school. After a year there, I came to LASA HS. I do not have much knowledge in baseball but with my degrees, I am able to check biomechanics and form to help with prevention of injury and increasing efficiency in movements.
Although I have never played baseball, I do play volleyball and all forms of it at that: grass, sand, indoor. Outside of work, I try to play as much as I can. I also take my time to explore the city with friends by going out to eat, going to concerts, and going to free venues. Being from Houston, I cheer on the Houston Astros but do not keep up with any sports in general, sorry to say. I already watch a lot of sports as it is. I’ll cheer on the Raptors any day!
