Definition:

The last bowler in a bowling-team lineup.

No matter how many bowlers are on your team, the last one in the lineup is your anchor. This is the bowler you trust more than anyone to throw a strike when needed, as he or she will be your final chance to shut out an opponent or make a comeback in the 10th frame.

Examples: After four years of bowling first in the lineup and leading his team in average, Bill finally took the responsibility of bowling in the anchor position and bowled last.
