At the bottom of the NL West are the Colorado Rockies, whose latest loss left Troy Tulowitzki despondent. At the top are the Los Angeles Dodgers, who enter Friday night in high spirits following their best offensive performance. The Dodgers dominated these teams' only series of the year and now visit a Rockies team mired in a seven-game losing streak. Los Angeles (18-10) trounced Milwaukee 14-4 on Thursday as Yasmani Grandal had eight RBIs, tied for the third-highest single-game total in franchise history.
