Billy Bates has signed a pro deal with West Ham.
The centre-half joined West Ham in 2020 from Norwich City.
"I'm over the moon to sign my professional contract," Bates told whufc.com. "I can't believe it to be honest. I'm absolutely buzzing. It means that I've been rewarded for all the hard work that I've put in.
"I'm buzzing for myself and for my family. My family were all in shock, but they were so happy for me at the same time. It was a great moment for everyone.
"Obviously I've come back from a big injury this season and, as we go into the new season, I'm really hopeful of a year with no injuries. Then I'll have the opportunity to show what I'm about.
"For me, I just want to take any opportunities that I get with both hands. I want to show everyone at this Football Club what I am capable of."
