Who is that handsome pro athlete?
These days, we can often see Japanese professional baseball players play in the major leagues.
Koichi is magnificent pro kendo player.
Remember that 手 can refer a "person" in some words? Well this is one of them. In this case, we have choose person, or perhaps a better way to think of it is like "chosen person." One situation in which you'd choose a person to do something is in sports, like in a schoolyard pick. Keep that in mind and you should be able to remember that this means pro athlete or sports player.
The reading for 選 is what you'd expect. 手 is the on'yomi reading as it is every once in a while, especially when it has to do with representing a person, so you'll have to remember that. I think you've seen 手 using this reading enough to be able to remember it, though.
