Houston Astros

The Houston Astros (81-69) look to extend their winning ways in this crucial American League West matchup against the Texas Rangers (79-71) on September 15, 2025, at Minute Maid Park. Both teams are enjoying above-average seasons, but the Astros currently hold the upper hand in the standings as they look to solidify their position heading into the final stretch.

In their previous encounter, the Astros showcased their prowess with a dominant performance, taking the game decisively. They will be sending Jason Alexander to the mound, who, despite being ranked 236th among MLB starters, has found some footing this season with a 4-1 record and a respectable ERA of 4.19. Alexander projects to pitch around 5.4 innings tonight, with an average of 2.8 earned runs allowed, which aligns with his trend of being a fortunate pitcher this year.

On the other side of the diamond is Jack Leiter, who has struggled with control issues this season, reflected in his high walk rate of 11.3%. Despite his underwhelming overall performance, including a bad 4.64 xFIP, Leiter has managed to maintain a solid 3.81 ERA. He projects poorly tonight, averaging just 4.9 innings pitched and allowing 2.8 earned runs, which could be problematic against a Houston lineup that ranks 13th overall in the league.

While the Astros’ offense is solid with a top 7th ranking in batting average, the Rangers’ offense has struggled, ranking 25th in MLB. With Alexander’s ability to neutralize the Rangers’ low-powered lineup, this could tilt the advantage firmly in favor of Houston. Betting markets have set the Astros’ moneyline at -125, indicating they are seen as slight favorites in what could be a tightly contested game. Overall, this matchup offers an intriguing look at how two teams are performing as they approach the postseason.

Texas Rangers Insights

• Jack Leiter – Over/Under 15.5 Pitching Outs (+135/-175)
  Considering both his underlying tendencies and the matchup, Jack Leiter is projected to throw 85 pitches in this matchup by the leading projection system (THE BAT X) system, which is the 7th-most on the slate today.
  Explain: Pitchers who throw a lot of pitches are more likely to go deeper into the game, record more outs, and generate more strikeouts.
• Jake Burger – Over/Under 0.5 Hits (-255/+190)
  Jake Burger is penciled in 4th in the lineup in this game, which would be an upgrade from his 68% rate of hitting in the bottom-half of the batting order this year.
  Explain: The higher in the order a player bats, the more plate appearances he will get and the more opportunities he will get to hit the Over for every market. A player who hits higher in the order than he normally does may provide extra value opportunity since the market may be based on him hitting lower.
• Josh Jung – Over/Under 1.5 Total Bases (+155/-205)
  Josh Jung hits many of his flyballs to center field (40.6% — 99th percentile) and will be challenged by the game’s 9th-deepest CF fences today.
  Explain: This player’s skill set does not match up particularly well with the park he’s in today, which may lead to worse-than-usual performance.

Houston Astros Insights

• Jason Alexander – Over/Under 4.5 Strikeouts (-110/-120)
  Considering the 0.66 deviation between Jason Alexander’s 7.42 K/9 and his 6.77 estimated true talent K/9 (via the leading projection system, THE BAT), it’s safe to say he’s been one of the most fortunate pitchers in the league this year as it relates to strikeouts and ought to negatively regress in the future.
  Explain: Pitchers that are overperforming should be expected to pitch worse going forward, which can create value on K prop Unders if the lines are too heavily weighing the lucky, to-date overperformance.
• Christian Walker – Over/Under 0.5 Total Bases (-155/+120)
  Christian Walker has been hot recently, raising his seasonal exit velocity of 90.6-mph to 96.2-mph in the past 7 days.
  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.
• Houston Astros – Moneyline (-130)
  The Houston Astros projected batting order projects as the 2nd-best of all teams today in terms of overall hitting skill.
  Explain: A pitcher who faces a strong opposing offense will be more likely to underperform his usual performance, particularly in terms of hits and runs, in that game.
