Josh Naylor (NA) Under 1.5 Total Bases (-196)

Odds available at draftkings at time of publishing

As the Tampa Bay Rays host the Seattle Mariners, all eyes will be on Josh Naylor and his quest for total bases. However, the trends suggest that he might struggle to clear the 1.5 mark. Naylor has faced lefties with inconsistent results, and today’s matchup against the Mariners’ southpaw, who boasts a solid strikeout rate, could stifle his bat. The Rays’ lineup has been adept at neutralizing opposing hitters, particularly at home, where they’ve limited extra-base hits effectively. Plus, Naylor’s recent form shows a dip in power against left-handers, making that 1.5 line feel a bit ambitious. Given the way the Rays have been pitching and Naylor’s current struggles, betting the under here seems like a prudent choice. With the numbers supporting a lower output, it’s hard to envision him racking up those bases against this formidable Tampa pitching staff.

Tampa Bay Rays vs Seattle Mariners : Tampa Bay Rays Win (-114)

Odds available at NA at time of publishing

As the Tampa Bay Rays gear up to face the Seattle Mariners, this matchup feels ripe for a Rays victory. Tampa is riding a wave of momentum, showcasing a powerful offense that’s been particularly effective at home. Over the last few weeks, they’ve averaged nearly 5.5 runs per game at Tropicana Field, making it tough for visiting pitchers to find a groove. On the flip side, the Mariners have struggled to find consistency, especially against left-handed pitchers, which plays right into the Rays' hand if they deploy one of their southpaws. With their bullpen also ranking among the league's best, Tampa is well-equipped to protect a lead late in the game. Add to that their impressive home record, and it's clear why the Rays are favored here. Given their current form and the Mariners' recent woes, backing Tampa Bay to take this one feels like a smart play.
