"The White Sox hit seven home runs during Saturday's game against the Blue Jays at U.S. Cellular Field, and made dubious history in the process. Those seven long balls, all amazingly of the solo variety, were not enough to prevent a 10-8 loss. The White Sox matched a single-game club record for home runs, set on April 23, 1955, but also joined the Tigers (May 28, 1995, against the White Sox and Aug. 8, 2004, against the Red Sox) as the only teams in Major League history to lose a game when hitting seven home runs." - Merkin, Scott. White Sox hit 7 HRs in loss, tie MLB record. 25 June 2016.
