Dallas Keuchel wanted to be the aggressor Thursday night against the Boston Red Sox. “It just seemed like I wasn’t able to get into a rhythm,” the Chicago White Sox starter said. “A few good pitches sprinkled in but a lot of pitches out over the plate and a couple of cutters that really didn’t get to the spot that I wanted to.” Keuchel allowed six runs on seven hits and lasted just two innings in a 16-7 loss to the Red Sox in front of 24,896 at Guaranteed Rate Field. “When he’s right, he’s giving up ground balls,” White Sox manager Tony La Russa said.
