open daylight
v. phr.— «In the last 20 years, just four favorites have won the Belmont Stakes. That trend will continue tomorrow when a big longshot, Globalize, scoots to the lead on the far turn, opens daylight and outlasts the favorite, Aptitude, in the 132nd Test of the Champion.» —“Go For The Global Goodie ; Longshot Is Primed For Belmont Stunner” by Ed Fountaine New York Post June 9, 2000.
