Swarzak (3-2) allowed two runs on three hits in two-thirds of an inning in Sunday's 7-3 loss to the Blue Jays.

Swarzak's season has taken a bad turn since the middle of May. The journeyman right-hander opened the year with 19.2 scoreless innings, helping the White Sox weather a storm of injuries in the bullpen, but has allowed 11 runs, 22 hits and six walks over 12.2 innings since then.
