Peterson hung Tampa Bay at +151, implying San Diego should be closer to –151, so he is happy to lay the current –120ish number with the Padres. He admitted Randy Vasquez is volatile—dominant for two starts before being shelled by Detroit—but still prefers him to Zack Littell, who brings a contact-heavy profile and barely seven strikeouts per nine. San Diego’s lineup is rounding into form with Fernando Tatis Jr. healthy, Luis Arraez setting the table and Manny Machado heating up, whereas the Rays are still searching for offense beyond Yandy Diaz and a hobbled Randy Arozarena. With Petco’s spacious dimensions, a ground-ball leaning Vasquez should keep the ball in the yard, and the Padres can deploy Robert Suarez and Wandy Peralta in leverage spots. Peterson would play San Diego to –135 and, with his model spitting out 7.9 runs, is neutral on the flat eight but looks to pair the money-line position with live unders if it creeps to 8½.
