All 30 MLB Teams Ranked by Defensive Efficiency: 2026 Season

Which Teams Have the Best Defenses in MLB?

These teams turn more balls in play into outs than anyone else, which directly suppresses opponent run scoring and makes their pitching staff look better than the raw numbers suggest.

Toronto Blue Jays return most of a unit that already finished top-five in 2025 defensive rankings. Bo Bichette's range at shortstop and George Springer's steady work in center field anchor a defense that is athletic at every position. Their defensive quality amplifies their pitching staff in ways that their team ERA projection doesn't fully capture. When you're betting Blue Jays games on totals, the defense is a legitimate additional under signal on top of whatever the pitching matchup already suggests.

Chicago Cubs ranked second in Defensive Runs Saved in 2025 with 80 DRS and are projected among the best defensive teams again in 2026. Their versatile defenders and strong corner gloves make them one of the most complete run-prevention teams in the National League. The Cubs' defense is a real reason their team ERA consistently outperforms what the individual pitcher projections would suggest.

Arizona Diamondbacks are expected to join the very top defensive group in 2026, with a young and rangy core that projects for significant improvement from an already competitive defensive unit. Their upside on defense is the most interesting development in that top tier because the market hasn't fully priced it in yet.

Boston Red Sox tied near the top in DRS last season at around 38 to 39, and their pickups and internal development give them a strong projected 2026 defense. Their combination of pitching and defense makes them a strong totals under team in matchups against average or below-average offenses.

Cleveland Guardians are historically one of the strongest fielding organizations in baseball and are projected top-five again with a stable core and strong infield range. Their defensive identity has been consistent enough over multiple seasons that you can factor it into every totals decision involving them with confidence.

Other elite or near-elite defensive units appearing in DRS top tables and projection commentary:

• Los Angeles Dodgers: Their combination of elite pitching and strong defense makes them the most complete run-prevention team in baseball.
• Baltimore Orioles: Athletic up the middle with strong range at multiple positions.
• Atlanta Braves: Solid defenders at key positions that amplify an already strong pitching staff.
• Houston Astros: Historically excellent defensive organization that continues to prioritize fielding quality in roster construction.
• Texas Rangers: Strong defensive construction at multiple positions that supports their pitching in ways the ERA numbers reflect.

Which Teams Have Average Defenses?

These teams have a few plus defenders offset by a few below-average ones, netting out to roughly neutral defensive value. Their defense neither helps nor hurts their pitching meaningfully.

• New York Mets: A couple of strong gloves with a few defensive liabilities that keep them in the league-average band overall.
• New York Yankees: Strong in certain positions, below average in others. Their overall defensive value is roughly neutral despite having individual defenders who grade above average.
• Seattle Mariners: Capable defense that doesn't create a significant edge or liability. Their pitching carries the team ERA more than the defense does.
• Tampa Bay Rays: Well-positioned defensively through smart roster construction but not dramatically above average by DRS in recent seasons.
• Philadelphia Phillies: Middle-of-the-pack defensive unit with a few standout gloves and a few below-average spots that balance out.
• Milwaukee Brewers: Average overall with some positional strengths that keep them competitive without making defense a primary betting factor.
• Minnesota Twins: Solid at certain positions with real questions at others. Their defensive value sits in the neutral zone for most betting purposes.

For totals betting, these teams are defensively neutral. The pitching matchup and offense level matter more than the glove work when you're deciding on totals involving this group.

Which Teams Have the Worst Defenses?

These teams gave up extra runs in 2025 through poor fielding and project to do the same in 2026. Their defensive inefficiency inflates staff ERAs, extends opposing at-bats, and makes their pitching look worse than the individual arm quality deserves.

• Colorado Rockies: Poor defensive efficiency compounded by extreme altitude makes their games at home genuinely chaotic. Every defensive mistake at Coors gets amplified by the park environment.
• San Diego Padres: Graded poorly in 2025 DRS and not featured in 2026 best defense projections. Their bat-first construction sacrifices defensive quality in ways that show up in their staff ERA.
• Chicago White Sox: Bottom-tier defensive unit on a rebuilding roster where fielding quality is not a current priority. Opponents benefit from extra at-bats and scoring opportunities throughout their schedule.
• Oakland Athletics: Rebuilding roster with young defenders still developing. Their defensive inefficiency creates additional run-scoring opportunities for opponents beyond what the pitching matchup alone would suggest.
• Washington Nationals: Full rebuild situation means defensive quality is inconsistent and often below average. Their combination of weak pitching and poor defense makes them one of the strongest fade candidates in baseball against quality opponents.

How Defensive Rankings Should Change Your MLB Bets

Defense creates specific betting edges that show up in totals and run line decisions every night.

• Totals betting: Elite defensive teams push totals toward the under by converting extra outs that weaker defenses wouldn't make. When an elite defense backs an elite rotation, the under is even more compelling. When two poor defensive teams meet, extra innings get extended and runs accumulate faster than the total accounts for.
• Team ERA context: Always check the defense behind a pitching staff before committing to a totals bet. A pitcher with a 3.50 ERA behind an elite defense like the Cubs or Blue Jays gives up fewer runs than the same pitcher behind a poor defense like the Rockies or White Sox.
• Run line value: Elite defensive teams cover run lines at higher rates as favorites because they don't give up cheap extra-base hits that keep opponents in games. Poor defensive teams as favorites on the run line are riskier than their pitching matchup suggests because extra defensive mistakes cost runs at the worst moments.
• Live betting: If an elite defensive team commits an early error that leads to unearned runs, the live total often overcorrects upward. Those errors normalize over the course of a game, which creates live under value before the market fully adjusts.
