open up daylight
v. phr.— «Bellamy Road, who not only opened up daylight (that’s equine parlance for “a can of whoop-ass”) on his rivals at last weekend’s Wood Memorial (huh, you said…Oh, shut it) but also broke a 13-year-old stakes record in the process.» —“Ladies and Gentlemen, Start Your Equines” by Kat Thompson SportsFan Magazine Apr. 14, 2005.
