David Mark Eckstein, (born January 20, 1975 in Sanford, Florida), nicknamed "Just Enough", is a Major League Baseball shortstop for the Toronto Blue Jays. He is noted for his size, as he is a small (for professional sports) 5' 7", but weighs 175 pounds. Eckstein's name is pronounced (ECK-styne) and means "cornerstone" in German. His "entrance music" is Ludacris's "Number One Spot" (appropriate since Eckstein usually bats as the leadoff hitter) and Crystal Method's "Busy Child".
