Act of leveling all the pins with the first bowl; also, the score thus made. Sometimes called {double spare}. 3. (Baseball) Any actual or constructive striking at the pitched ball, three of which, if the ball is not hit fairly, cause the batter to be put out; hence, any of various acts or events which are ruled as equivalent to such a striking, as failing to strike at a ball so pitched that the batter should have struck at it. 4. (Tenpins) Same as {Ten-strike}; web1913: Strike \Strike\, n. 1. The act of striking. 2. An instrument with a straight edge for leveling a measure of grain, salt, and the like, scraping off what is above the level of the top; a strickle. 3. A bushel; four pecks. [Prov. Eng.] --Tusser. 4. An old measure of four bushels. [Prov. Eng.] 5. Fullness of measure; hence, excellence of quality. Three hogsheads
