The San Diego Padres head into Chase Field to face the Arizona Diamondbacks in a NL West scrap that still matters, with the Padres at 59-56 and the Diamondbacks a touch better at 61-54. Vegas has San Diego as light favorites at -106 with the total sitting at 9, so bettors expect some offense even with a night game on tap.

This is the kind of getaway-day energy where a shaky bullpen outing decides everything, so watch for whoever's manager goes to the pen too early. Bold prediction: the heart of the Padres order gets to a southpaw starter early and this one ends with a ball leaving the yard in the eighth.
