Kansas City Royals vs. Texas Rangers: A Tale of Two Teams (and a Moneyline)
June 18, 2025 | Globe Life Field | First Pitch: 8:05 PM ET
The Setup: A Clash of Contradictions
The Kansas City Royals (-136) enter this matchup as the slight favorite, despite a six-game losing streak, a .366 team slugging percentage (4th-worst in MLB), and a 14-16 record when favored this season. Meanwhile, the Texas Rangers (+120) are the underdogs, but they boast a 3.11 ERA (2nd in MLB), a pitching staff that’s been better than the Royals’ (3.44 ERA), and a lineup featuring Marcus Semien and Adolis Garcia. The only thing more baffling than the Royals’ moneyline is their offense—which has hit a MLB-low 46 home runs.
The Numbers Game: Why This Game Feels Like a Coin Flip (With a Slight Tilt)
Royals’ Case for the Crown:
- Kris Bubic (5-4, 1.92 ERA, 82 Ks) is aces in the making, but can he outpitch an unnamed Texas starter? Spoiler: Probably not.
- Bobby Witt Jr. (.337 OBP, .468 SLG) is their lone offensive spark, but the rest of the team slugs like a sleep-deprived sloth.
- Historical Context: The Royals are 14-16 as favorites this season. Not exactly a dynasty.
Rangers’ Underdog Gambit:
- Pitching Dominance: Texas’ 3.11 ERA is second in MLB, and their 1.141 WHIP is the best in baseball. They’ve allowed just 3.5 runs per game.
- Offensive Edge: Marcus Semien (.315 AVG) and Adolis Garcia (18 HRs) can exploit the Royals’ porous defense (29th in team ERA).
- Underdog Magic: MLB underdogs win 41% of the time. The Rangers are 11-35 as underdogs this season, but they’re 3-15 when priced at +116 or higher. That’s a red flag… or a green light, depending on your risk tolerance.
Odds Breakdown: The Math Doesn’t Lie (Mostly)
Implied Probabilities:
- Royals (-136): 57.6% chance to win (100 / (100 + 136)).
- Rangers (+120): 45.5% chance to win (100 / (100 + 120)).
Expected Value (EV) Analysis:
- Royals: Their implied 57.6% win rate vs. their actual 46.7% (14-16 as favorites) = overvalued by 10.9%.
- Rangers: Implied 45.5% vs. MLB underdog rate of 41% = undervalued by 4.5%.
Split the Difference:
Adjust the Rangers’ implied probability by half the gap between their line and the underdog rate:
45.5% (implied) – (45.5% – 41%) / 2 = 43.2% adjusted win chance.
EV for Rangers:
(43.2% * 1.20) – (56.8% * 1) = 0.518 – 0.568 = -0.05.
Still a slight negative, but closer to break-even than the Royals’ EV of -0.11.
The Verdict: Bet the Underdog, But Don’t Celebrate Yet
While the math suggests the Rangers are slightly undervalued, the EV is still negative. However, context trumps cold numbers:
- The Royals’ offense is so bad it could make a vegan weep.
- The Rangers’ pitching is elite, and they’ve thrived in high-pressure games (e.g., 2023 ALCS).
- Bubic is excellent, but even he can’t outpitch a team with a 3.11 ERA.
Best Bet: Texas Rangers (+120)
- Why? The Rangers’ pitching and the Royals’ offensive futility create a mismatch. The line doesn’t fully account for Kansas City’s struggles.
- Risk Factor: High. But underdogs win 41% of MLB games. This feels like a 45% chance game.
Alternative Play: Over 8.5 Runs (-110)
- Both teams score 4.5 runs/game on average. With Bubic’s 1.92 ERA vs. a potent Texas lineup, this game could erupt.
Final Thought:
The Royals are the favorite because they’re the only team with a .500 record in this matchup. But in baseball, pitching wins games, and the Rangers have it in spades. Bet the Rangers, and if they lose, blame the “overrated” moneyline.
