a goal each from

[Atchan]

What is the meaning of this highlighted paragraph? Is it called a paragraph I don't know?

Argentina's World Cup campaign has ended in tears as Germany have hammered them 4-0 in the quarterfinal to progress to the semis. A brace from Miroslav Klose and a goal each from Thomas Mueller and Arne Friedrich secured the Europeans a berth in the last four.

Is "semis" is a shortage of semi-final? Why they didn't say "semi" without "S".
I see in many sport websites that when they're writing quarter final they bush the two words together like this "quarterfinal" Isn't wrong?

Cheers!

Not a teacher.

Yes, "semis" is short for "semifinals." It is plural.

"A goal each" means each player mentioned scored one goal.

Nice, that made sense.
