Bregman is out of the lineup Sunday against the Athletics.
According to Kaplan, it's strictly a rest day for Bregman, who has come out of the gate a bit sluggishly this season with a .250/.340/.310 batting line across 98 plate appearances. Manager A.J. Hinch attributed some of Bregman's early struggles to the youngster's unorthodox spring training schedule due to the World Baseball Classic, but the Astros remain optimistic he'll heat up before long. Marwin Gonzalez will spell Bregman at third base Sunday.
