Texas Rangers

As the Texas Rangers prepare to host the Miami Marlins on September 19, 2025, both teams find themselves in different places in the standings. The Rangers currently sit at 79-74, enjoying an above-average season, while the Marlins, at 73-80, have struggled and are below average. This matchup carries significance, especially since it’s the first game of a series that could affect both teams’ momentum heading into the final stretch of the season.

In their last outings, the Rangers fell to their opponents with a score of 5-2, while the Marlins secured a victory, winning 9-7. This recent performance could give Miami a psychological edge, but the Rangers will look to rebound at Globe Life Field, where they have home-field advantage.

On the mound, Texas is projected to start Tyler Mahle, a right-handed pitcher with a respectable 2.34 ERA this season, although his 4.48 xFIP suggests he may have been a bit lucky thus far. Mahle has a win/loss record of 6-3 and is known for his ability to limit earned runs, projecting to allow 1.8 earned runs today. However, he also has a tendency to pitch fewer innings, averaging just 4.2 innings per start this year, which presents a challenge for the Rangers’ bullpen.

In contrast, the Marlins will counter with Janson Junk, another right-handed pitcher whose performance has been less stellar. With an ERA of 4.48 and a FIP that indicates he might improve, Junk has also posted a 6-3 record. He projects to pitch around 5.1 innings, allowing about 2.7 earned runs.

The Rangers’ offense has been subpar, ranking 25th in MLB, which could hinder their ability to capitalize on Mahle’s strengths. However, with a high implied team total of 4.39 runs for today’s game, there’s potential for the Rangers to outperform expectations, especially against a Marlins bullpen that ranks 27th in MLB. As the teams clash, the Rangers will need to find ways to break through against a Marlins squad that remains dangerous despite their struggles.

Miami Marlins Insights

• Janson Junk – Over/Under 3.5 Strikeouts (-110/-120)
  Contrary to popular belief, fastballs are generally a pitcher’s least effective pitch. Janson Junk must realize this, because he has gone to his secondary pitches a lot this year: 62.6% of the time, placing in the 83rd percentile.
  Explain: A pitcher who limits has fastball usage will instead heavily use change-ups, curveballs, sliders, etc. These are far more effective pitches at preventing runs and generating strikeouts.
• Eric Wagaman – Over/Under 0.5 Total Bases (-135/+105)
  Eric Wagaman has been hot in recent games, raising his seasonal exit velocity of 91.1-mph to 95.6-mph over the last two weeks.
  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.
• The Miami Marlins have been the 2nd-luckiest offense in the league this year, according to the leading projection system (THE BAT X), and are likely to perform worse in future games
  Explain: When teams overperform their projected talent level, markets may overvalue them even while they are likely to perform worse in the near future.

Texas Rangers Insights

• Texas Rangers – Moneyline (-150)
  Among every team on the slate today, the 5th-weakest infield defense belongs to the Texas Rangers.
  Explain: Defense is an integral part of preventing (or, in this case, allowing) hits and runs.
• Jake Burger – Over/Under 1.5 Total Bases (+115/-145)
  Despite posting a .305 wOBA this year, the leading projection system (THE BAT X) believes Jake Burger has experienced some negative variance given the .041 gap between that figure and his estimated true talent wOBA of .346.
  Explain: Players that are underperforming should be expected to play worse going forward, which can create value on prop Overs if the lines are too heavily weighing the unlucky, to-date underperformance.
• Texas Rangers – 2H Moneyline
  According to the leading projection system (THE BAT), the Texas Rangers’ bullpen projects as the 9th-best out of all MLB teams.
  Explain: Most bettors only consider the starting pitcher, but a strong bullpen sneakily creates a tougher matchup for the opposing offense and suppresses a game’s runs.
