Tampa Bay Rays

Washington Nationals
(-110/-110)+120
The Washington Nationals will face off against the Tampa Bay Rays on August 30, 2025, in the second game of their interleague series at Nationals Park. After a tough loss yesterday, the Nationals, who have struggled considerably this season with a 53-81 record, are looking to regain momentum. Meanwhile, the Rays sit at 65-69, not quite contending but still holding their ground with an average season.
In this matchup, the Nationals are projected to start Jake Irvin, who has had a challenging year, posting an 8-9 record and a 5.40 ERA this season. Although Irvin has been unlucky with a 4.83 xFIP, his tendency to allow 5.9 hits and 1.4 walks per game signifies potential troubles against a well-rounded Rays offense. The Nationals rank as the 24th best offense in MLB and struggle with power, sitting at 28th in home runs, making it tough for them to capitalize on any mistakes.
Ryan Pepiot, slated to pitch for the Rays, boasts a solid season with a 3.82 ERA and a 9-10 record. While his FIP suggests some regression may be in store, he performs well against a Nationals lineup that has limited power. Pepiot’s high flyball percentage might not be an issue today, given Washington’s struggles to translate opportunities into homers.
The projections favor the Rays significantly, with an implied team total of 4.89 runs compared to the Nationals’ 4.11. After a weak outing by the Nationals’ offense yesterday, facing an above-average arm like Pepiot could pose a daunting challenge. With these factors in play, bettors might find value in leaning towards the Rays in this matchup.
