Stumps?

After reading these paragraphs, taken from an online news source, can you name the sport and what the terminology means*?

Bangladesh captain Shakib Al Hasan thinks England would be facing defeat in the second Test if the television referral system was in place in Mirpur.

Ian Bell, Matt Prior and Tim Bresnan survived close calls as England took a 21-run lead at stumps on day three.

"You have seen the TV. You have seen what the decisions were and what the decisions should have been," said the 22-year-old Tigers skipper.
"It is really bad for us that we did not use the referral system."

I'm sure our discussions of baseball and basketball can sound just as esoteric.

* Me neither. Stumps?
