four-three unassisted double play

"[Texas Rangers second baseman Ian] Kinsler with a four-three unassisted double play."
-- Commentator on Sportsnet Pacific's Toronto Blue Jays broadcast, Wednesday April 16th 2008

Kinsler picked up the grounder, touched second base for a force out, then threw the ball to first for the second out. So it was indeed a 4-3 double play. But it took two players to make the play, so it's the opposite of unassisted. Just hearing, or reading, four-three is enough to tell you that it was unassisted. If Kinsler had caught a line drive and then tagged the baserunner out, that would be an unassisted double play.
