Get your game face on

[Ksguo]

My second post
Some conservative US senators seem to be very uncomfortable with Obama's nomination of Sonia Sotomayor to Supreme Court because of her so-called ‘racist’ remarks made in 2001，and may be hard on her during senate confirmation hearings.So a White House team will ‘coach Sonia Sotomayor through confirmation process’，as a CNN report titled ‘Prepping Sotomayor for hearings: Get your game face on’ tells us.What is the meaning of the phrase ‘get your game face on ’in this context，please？

'Get your game face on' is an idiom meaning to get serious, concentrate on, and prepare for something in a effort to succeed.
