With one out, Alejandro De Aza doubled before Grant Balfour (0-1) walked Tyler Flowers and Paul Konerko. Adam Eaton grounded into a force out at second, but it was enough to score De Aza. Balfour then walked Marcus Semien before serving up Abreu's grand slam.
Balfour left a fastball up for the Cuban rookie, who hammered the pitch over the wall in right field.
