"I've followed Koichiro for a couple years now and I've seen him play a lot of great golf. He's worked hard to get his game and language skills to the point to attend ASU and I'm proud of him for what he has already accomplished and excited about what the future could hold for him here at ASU. He has excellent golf skills and a fun personality."--Sun Devil Head Coach Matt Thurmond.
