Understanding the "Welsh" [closed]

What is meant by Welsh ? I searched it but still it is confusing for me in the below case. I didn't understand the exact meaning of this.

"What happened to you guys helping us out by winning the Welsh?"

Can you please explain what does it mean


Solution 1:

In the same vein as Chris H has suggested, could refer to winning the Welsh Open or another event with the word “Welsh” in the name. But yeah, generally it refers to the language or people from Wales. Beating the Welsh could also refer to beating them in a war or battle, historically.
