Houston Astros

As the Colorado Rockies travel to Minute Maid Park to face the Houston Astros on August 27, 2025, they find themselves in the midst of a dismal season with a record of 38-94. The Astros, conversely, are having an above-average year at 72-60, bolstered by their 11th-best offense in terms of batting average. Both teams are coming off a game yesterday, with Houston clinching a comfortable victory, continuing their push for a playoff spot.

Houston is projected to start Framber Valdez, who has been one of the league’s standout pitchers with a Power Ranking placing him 19th among around 350 pitchers. Valdez’s excellent ERA of 3.32 reflects his prowess, and he projects to pitch an effective 6.3 innings while allowing only 2.0 earned runs today. His ability to generate strikeouts at a rate of 7.1 per game significantly increases his effectiveness against a Rockies offense ranked 26th overall.

On the mound for Colorado is Chase Dollander, who has struggled throughout the season with a record of 2-10 and a concerning ERA of 6.91. Although projections suggest he might be slightly better today, allowing 2.9 earned runs, his high walk rate could be problematic against an Astros lineup that is 6th in the league for fewest walks.

Despite a mediocre bullpen ranking of 22nd, the Astros are heavy favorites today with a moneyline of -310, reflecting their high implied team total of 5.07 runs. The Rockies, meanwhile, struggle with a projected team total of just 2.93 runs, showcasing the stark contrast in performance expectations between the two clubs. With Houston’s potent offense and a struggling pitcher like Dollander on the mound for Colorado, this matchup heavily favors the Astros.

Colorado Rockies Insights

• Chase Dollander – Over/Under 4.5 Strikeouts (+120/-155)
  Chase Dollander’s high usage percentage of his fastball (57.5% this year) is likely dampening his results, consider they are typically much less effective than breaking or off-speed pitches.
  Explain: Fastballs are the one easiest pitches to hit and generate few strikeouts, so pitchers who rely too heavily on them tend to be less effective than they otherwise would be.
• Warming Bernabel – Over/Under 0.5 Total Bases (-170/+130)
  Warming Bernabel has been cold lately, with his seasonal exit velocity of 85.8-mph dropping to 79.7-mph in the past week’s worth of games.
  Explain: Hitting the ball hard increases the chances of either a home run or the ball landing in fair territory for a hit before a fielder can get to it.
• Compared to their .317 overall projected rate, the .303 the leading projection system (THE BAT X) wOBA of the Colorado Rockies projected batting order today suggests this version of the lineup quite a bit weaker than usual.
  Explain: Betting lines are often based on seasonal team quality. If today’s lineup is watered down, however, there may be value if markets aren’t accounting for the lower quality of this offense.

Houston Astros Insights

• Houston Astros – 1st Five Innings (F5) Moneyline (-300)
  Framber Valdez turned in a great performance in his last start and allowed 0 ER.
  Explain: A pitcher who was strong in his last outing may be sharp once again in his next outing.
• Jesus Sanchez – Over/Under 1.5 Total Bases (+115/-150)
  Based on Statcast metrics, the leading projection system (THE BAT X)’s version of Expected HR per 600 plate appearances (25.1) provides evidence that Jesus Sanchez has suffered from bad luck this year with his 16.0 actual HR/600.
  Explain: xHR uses highly advanced Statcast data to measure a player’s home run ability more accurately than actual home runs can.
• Houston Astros – 2H Moneyline
  According to the leading projection system (THE BAT), the Houston Astros’ bullpen projects as the 10th-worst out of all the teams in Major League Baseball.
  Explain: Most bettors only consider the starting pitcher, but a weak bullpen sneakily creates an easier matchup for the opposing offense and boosts a game’s runs.
