San Diego at Arizona

Arizona is getting too much respect from oddsmakers after that hot start on offense, losing six of 11. They lost two of those games as chalk, and the pitching is starting to regress, allowing 20 runs the last four contests. Arizona has lost five of seven games when Zack Greinke starts against the NL West, and division rival San Diego is in town. The Padres have quietly won three of five, including a 1-0 win over Arizona and Greinke as a dog. Padres righty Jhoulys Chacin goes tonight and had his best outing with the team in that start, getting the win after allowing only three singles and a walk while striking out five D-Backs. San Diego has won six of eight against a team with a winning record, so back the dog. Play San Diego.
