San Diego Padres Pitcher Mason Miller

Mason Miller is a relief pitcher for the San Diego Padres. He’s known for his fastball (often 100+ mph!) and cutter/slider, earning praise as one of baseball’s best relievers.

Breakthrough T1D sat down with Mason to learn more about his journey with type 1 diabetes (T1D) and the impact it has on him as a star athlete.

Q: What’s your T1D story?

A: I’ve now lived with type 1 diabetes for almost 8 years. I was diagnosed at the age of 20 during my sophomore year of college. I had lost about 25 pounds and was exhibiting all the tell tale signs, but thought no way it could be T1D. I was active, ate fairly well, why would it happen to me? Regardless, I was sent to Children’s Hospital in Pittsburgh, where I was diagnosed and educated on T1D. I really had no knowledge prior to my diagnosis. 

I learned the ins and outs of T1D quickly, but I do feel that living and learning has given me more and more confidence as I tackle it with my daily endeavors. Getting healthy and seeing a huge weight gain, I was able to have a ton of success on the baseball field. When I was diagnosed, I was struggling as a D3 pitcher and now I’m pitching in the MLB for the Padres. A lot of hard work accompanied getting healthy and educated, but I do feel grateful for the technology that allows me to take such good care of myself. 

Q: Why is T1D visibility important to you?

A: Visibility is important to me because of the platform I have as an athlete. I’m fortunate to have an opportunity to draw attention to things that matter to me. Type 1 diabetes is close to my heart as I live with it each day. I have a unique opportunity to connect with young kids and show them that T1D does not hold you back. You can still have and achieve dreams just like everyone else. 

Q: What is one T1D misconception that you REALLY dislike? 

A: That lifestyle, diet, or something I did caused my diagnosis.

Q: What is something you wish people knew about life with T1D? 

A: The habits and routines that we develop mean a lot. With everyone, healthy habits are important but for people living with T1D, it’s crucial. Physical activity and diet go a lot further than physique or stamina. They help us create stable sugar levels in healthy ranges. 

Q: Is there a routine, tool, or mindset that’s been especially helpful for you on game days?

A: My continuous glucose monitor (CGM) is a game changer. You learn so much about how different things affect you. It gives me the confidence to play without a second thought because I know my glucose and how it will react.

Q: How do you stay mentally strong while juggling a professional sports career and T1D? 

A: Having a support system is incredibly important. My wife is, and will continue to be, my biggest supporter. But coaches, teammates, and others all can teach you something from their words or actions. I try to always be learning from those around me. I handle T1D like it’s normal for me. I still expect those around me to hold me to a high standard. It’s not a crutch. It’s an opportunity. 

Q: What message do you hope your story sends to young athletes with T1D?

A: I always hope that my story is an inspiration to those living with T1D. Whether they have aspirations in sports or elsewhere, I hope my story gives them confidence to chase their dreams.
