The Washington Nationals vs. Colorado Rockies: A Tale of Two Teams, One Disaster Waiting to Happen
By The Handicapper Who Still Dreams of a Perfect Bracket
The Setup
The Washington Nationals (30-42) host the Colorado Rockies (15-57) in what might be the most one-sided game since a toddler tried to beat a vending machine with a juice box. The Nationals, favored at -190, are coming off a 6-4 loss to the Rockies in their previous meeting, where Hunter Goodman single-handedly out-homered the entire Nats lineup. Meanwhile, the Rockies, with a 57-loss season that’s already tied for the most in the Modern Era after 72 games, are the definition of a "throw the ball at the wall and see if it sticks" team.
Key Stats & Context
- Nationals’ Offense: Averaging 4.2 runs per game, but their pitching staff is a dumpster fire (4.94 ERA, 27th in MLB).
- Rockies’ Offense: A .225 team batting average (MLB’s worst) and a 5.60 ERA pitching staff (30th in MLB).
- Starting Pitchers: Mitchell Parker (5.14 ERA) for the Nats vs. Antonio Senzatela (7.23 ERA) for the Rockies. Senzatela’s ERA is so bad it makes a leaky faucet look like a Hall of Famer.
- Underdog Win Rate: Rockies have won just 20.3% of games as underdogs this season, far below baseball’s 41% average.
The Math: Calculating Expected Value (EV)
1. Implied Probabilities from Odds:
- Nationals (-190): 65.7% implied probability.
- Rockies (+160): 38.5% implied probability.
2. Actual Win Probability:
- Rockies’ 20.3% underdog win rate vs. baseball’s 41% average suggests they’re overpriced as underdogs.
- Nationals’ 2-9 record as favorites is a red flag, but their better offense (4.2 R/G) and slightly better pitching (4.94 ERA vs. Rockies’ 5.60) tilt the actual probability in their favor.
3. EV Calculation:
- Nationals: (65.7% implied vs. ~70% actual) → Positive EV.
- Rockies: (38.5% implied vs. ~20% actual) → Negative EV.
The Verdict: Best Bet
Washington Nationals (-190)
- Why? The Rockies’ pitching staff is so bad (7.23 ERA from Senzatela) that even the Nationals’ subpar offense (4.2 R/G) should find ways to score. Meanwhile, the Rockies’ .225 team batting average ensures they’ll struggle to scratch across runs. The Nationals’ 3-0 home series win streak against the Rockies since 2022 also adds a psychological edge.
Honorable Mention: Under 9.5 Runs (-110)
- The Rockies’ offense is so anemic (.225 BA) that they’ll likely score 3-4 runs. The Nationals’ offense (4.2 R/G) and Rockies’ pitching (5.60 ERA) could push the total to 7-9, making the Under 9.5 a solid secondary play.
The Wrap-Up
This game isn’t a contest—it’s a mercy rule waiting to happen. The Nationals are the only logical choice here, unless you’re a masochist who bets on the Rockies just to see how bad they can get. And let’s be honest, that’s the real underdog bet: watching this game without a sportsbook.
Final Prediction: Nationals 5, Rockies 2.
Best Bet: Washington Nationals (-190).
Expected Value: +EV due to Rockies’ abysmal performance as underdogs and Nationals’ superior offense.
“The Rockies are like a broken umbrella in a hurricane—useless, soggy, and destined to let you down.”
