Play: Money Line: -117 Arizona Diamondbacks
Take the DBacks Rotation #960 Arizona has the cleaner, more reliable path today because Eduardo Rodriguez has been one of the most dominant pitchers in baseball this season, and the Diamondbacks have been nearly automatic behind him. Arizona is 17–3 in his last 20 starts, and he enters tonight with a 2.48 ERA, seven quality starts in his last eight outings, and coming off eight scoreless innings in Pittsburgh. That level of stability is exactly what you want when backing a side. Meanwhile, San Diego turns to Randy Vásquez, who owns a 4.45 ERA and is part of a patchwork rotation the Padres are still trying to manage until their new acquisitions arrive. Arizona already handled the Padres 5–1 on Monday, and with the offense energized by deadline additions and “vibes good” in the clubhouse, they’re catching San Diego at a vulnerable moment. With the hotter team, the far stronger starter, and a matchup that leans heavily toward run prevention on the Arizona side, the Diamondbacks have the edge to beat the Padres again today.
