I am not looking for phrases that mean to keep your poise or have courage.
I am looking for something - word or phrase - the succinctly describes someone who is better under pressure.
An example would be a basketball player who shoots 3 pointers 35% overall but if he has a guy in his face he shoots 45% and if he has a guy in his face and in a close game in the 4th quarter he shoots over 50%. Is there something that summarizes the relationship between more pressure and more performance?
Edit: Clutch is a really good term and we had thought about using that. We need a term t:that fits into our database model for football/basketball advanced metrics. Was looking for something that is a little more scientific and not a current cliche but if the shoe fits we will use it. Still open to more suggestions.
