Single entry and double entry visa

So I’m in Uk for my studies and I want to apply for the visa for Spain. The thing I want to ask is that as it’s my first time applying , would they give me multiple entry visa. I need multiple entry as I’m planning on going different countries to play my Esports tournaments which are going to take place in February 2026. I do plan on attaching all the tournament dates and proof that I’m actually a Esports player by giving them my X media account and all my achievements with pictures of me in top 3 and top 8. Would this be a strong case ?
