Houston Astros vs. Washington Nationals preview

The Astros look to maintain their impressive season pace as they host the struggling Nationals at Daikin Park Monday night, with Houston's 60-43 record standing in stark contrast to Washington's disappointing 41-61 mark.

The pitching matchup features veteran lefty Framber Valdez, sporting a stellar career 79-45 record and 3.22 ERA, against the relatively inexperienced Brad Lord, who enters with a 2-5 career mark despite his promising 3.39 ERA.

Houston's pitching staff has been dominant this season, ranking 3rd in MLB with just 390 runs allowed while posting a collective 3.60 ERA, a stark contrast to Washington's pitching struggles that have resulted in a second-worst 5.20 team ERA.

The Nationals' offensive woes have contributed to their position near the bottom of the standings, scoring a modest 4.3 runs per game (17th in MLB), while the Astros' balanced attack has averaged a slightly better 4.38 runs per contest.

With Houston converting save opportunities at an impressive 73.3% rate compared to Washington's 58.8%, late-game situations could heavily favor the home team in what oddsmakers see as a clear mismatch.

The Astros' superior fielding percentage (.988, 6th in MLB) versus the Nationals' middle-of-the-pack defensive efficiency could be another deciding factor in a game where the fundamentals might make all the difference.
