Astros' Alex Bregman Out for White Sox Series with Elbow Swelling

MRI reveals no structural damage; Bregman expects to return for Boston series next week.

Bregman developed swelling after sleeping on his arm incorrectly, requiring rest.
An MRI showed no ligament damage, and Bregman is not placed on the injured list.
Mauricio Dubón takes over third base duties in Bregman's absence.
Bregman has been in strong form, hitting .444 with three homers last week.
The Astros, currently first in the AL West, will play the Red Sox after the White Sox.
