>Curtis Campher scores 72 not out and leads Irish victory over Scotland in Irelands highest ever run case

Curtis Campher scores 72 runs to win the game and score a record for Ireland.

"not out" = the batsmen continue to be at bat until being "out", which happens if the ball is caught in the air, the wicket is broken, or they are forced out while running.

Since he finished the game without that happening, he was "not out".
