awk: how to match the character start with and end with

I am using awk. I have several names like

Code:
rs123123789_G    rs9888_A     rs23789_GA rs23789_GASDFAS
I want to find the name start with rs and end with single character in awk (rs123123789_G, rs9888_A). I tried use

Code:
~/^rs[0-9]+[A-Z]$/
But it does not work.

Including an underscore in your regex might help.
