The Padres have had a solid start to the 2026 season and are sitting at the top of the NL West with a 27-18 record. San Diego took the first two games of this series in Seattle, including a 7-4 victory yesterday behind a strong performance from Manny Machado and Xander Bogaerts.

Seattle is looking to salvage the finale at home. The Mariners are 22-25 on the year and need a spark to get back to .500 in the competitive AL West. Playing in front of a home crowd gives them a lift, but they have to find a way to slow down San Diego's hot bats.

Best Bets for Padres vs. Mariners, May 17, 2026

• San Diego Padres Moneyline: The Padres have had the upper hand in this series, winning the first two games on the road. With their offense clicking, taking San Diego to complete the sweep is a popular angle.

• Under On Total Runs: T-Mobile Park is historically a pitcher-friendly park, and Sunday night games can sometimes turn into defensive battles. Looking at the under might be a smart choice if the starting pitching holds up early.

• Manny Machado to Record A Hit: Machado has been a reliable force in the Padres lineup throughout May. Betting on him to keep things rolling with at least one hit offers decent value for a player prop.
