A 10-4 White Sox lead over the Atlanta Braves had quickly dissolved into a one-run lead and a 10-9 game. Atlanta had already plated five runs in the seventh inning and were threatening for more. They had runners on first and second and two outs with the red hot Jurickson Profar up to bat.
After a 1-1 offering from Tyler Alexander, Quero made a snap throw over to first base and picked off Vidal Bruján, who had wandered too far off the bag.
It closed the flood gates, got the White Sox out of the inning, and temporarily saved the game.
