Rapid Reaction: Orioles 6, White Sox 4

CHICAGO -- The Chicago White Sox's troubles continued on Sunday with a 6-4 defeat to the Baltimore Orioles. They have lost five consecutive and 15 of their last 18.

How it happened: Gavin Floyd couldn’t prevent the big inning and the White Sox’s offense was ill-equipped to cover for it. Floyd gave up a solo home run to Mark Reynolds and a three-run double to Nick Markakis in a five-run fifth inning for the Orioles. The White Sox scored three runs after the sixth inning, only to see a ninth-inning rally fall short when both Paul Konerko and Alex Rios were called out on strikes.

What it means: After their franchise record 18 defeats in the month of April, the White Sox started May right where they left off. The lack of a clutch hit continues to be a problem. Down five runs in the seventh inning, the White Sox loaded the bases with one out but scored just one run. Adam Dunn's pinch-hit home run in the eighth inning was a sign of hope for a club that is desperate for the big man to deliver.

Fact of the day: The White Sox have now lost seven consecutive games at home after winning four of their first six.

Up next: White Sox left-hander Mark Buehrle (1-3, 5.12 ERA) pitches in the finale of the four-game homestand on Monday. Orioles right-hander Jeremy Guthrie (1-3, 2.53) is Buehrle's opponent in the 7:10 p.m. start at U.S. Cellular Field.
