The Astros (23-12) finally saw their 11-game winning streak snapped on Saturday in a 13-6 loss to the Nationals, but Houston responded with an 8-0 victory on Sunday. Not only are the Astros 12-1 since starting the season 11-11, but they have not allowed more than three runs in any of those 12 victories -- and half of them have been shutouts. Houston's starting rotation has a 3.05 ERA (fifth in MLB), while the bullpen's 2.69 ERA ranks second among all clubs.
