The Rockies’ upcoming road trip looms like a tough, early-season exam, especially for a starting pitching staff that has flashed potential, but also has created plenty of consternation. Impressive starts by left-hander Kyle Freeland Tuesday night in a 8-0 win over San Diego, followed by right-hander Jon Gray‘s powerful, 11-strikeout performance over the Padres in a 5-2 victory Wednesday at Coors Field, gives the Rockies something to build on as they head east. “We have a good chance to be at the top, with all of the rest of the high-end rotations,” said Freeland, who pitched seven scoreless innings of three-hit ball on Tuesday, striking out eight.
