The Washington Nationals (53-80) welcome the Tampa Bay Rays (64-69) to Nationals Park on Friday night in a matchup between two struggling clubs looking to salvage disappointing seasons.
While Tampa Bay enters as heavy favourites at -210 despite their own struggles, the Rays bring a more potent offence averaging 4.5 runs per game compared to Washington's 4.25, though both teams face significant pitching concerns with Adrian Houser and Mitchell Parker taking the mound.
With the Nationals riding a five-game losing streak and sitting last in the NL East, they'll need to find answers against a Rays squad that's fallen to second-worst in the AL East but still possesses enough firepower to exploit Washington's league-worst pitching staff.

Washington Nationals vs. Tampa Bay Rays preview
The Rays (64-69) arrive in Washington nursing back-to-back losses that have left them with the second-worst record in the AL East, while the Nationals (53-80) are mired in a five-game skid that epitomizes their forgettable campaign.
Adrian Houser takes the ball for Tampa Bay despite allowing 32 runs over his last 90 innings, though he'll be backed by a lineup that's actually been productive, averaging 4.48 runs per game behind Junior Caminero's 39 homers and Jonathan Aranda's .316 average.
The Nationals counter with Mitchell Parker, who's been torched for 100 runs in 134 innings and faces a tough assignment against a Rays offense that's managed to stay competitive despite the team's struggles.
Washington's attack has been anemic lately, managing just 10 runs over their last four contests, with only four regular batters posting an OPS+ above 100.
James Wood continues to flash his potential with 26 homers and a .480 slugging percentage, but the Nationals need more consistent production throughout the lineup to snap this ugly losing streak.
Both clubs are essentially playing out the string at this point, but the Rays still have enough offensive firepower to make things interesting in what should be a fairly high-scoring affair at Nationals Park.
