Left On Base (LOB) quantifies runners remaining on bases at inning's end. This baseball statistic often indicates missed scoring opportunities. In 2023, the Atlanta Braves led MLB with 7.8 LOB per game. This metric demonstrates offensive potential for advanced analytics platforms like FanGraphs.
TL;DR
Left On Base (LOB) tracks runners who fail to score before the third out occurs. High LOB numbers often indicate a team's inability to deliver hits with runners in scoring position. While individuals track LOB to gauge clutch performance, team LOB serves as a primary indicator of missed scoring opportunities during high-stakes games.
Why is LOB a Critical Statistic?
LOB measures how many runners occupied a base when the third out of an inning was recorded. It highlights the gap between a team's ability to get players on base and their ability to bring them home.
This stat appears in box scores under two different categories to help fans understand performance. Team LOB sums the total runners left at the end of every inning. Individual LOB calculates how many runners were on base when a specific batter made an out. This distinction helps scouts identify which players struggle during high-pressure plate appearances.

How Does LOB Impact Game Outcomes?
A high LOB count usually suggests a team is productive at reaching base but fails to execute the final hit needed to score. It often correlates with a low batting average with runners in scoring position (RISP).
While high LOB totals look negative, they actually require a team to be offensive enough to put runners on in the first place. A team that strikes out in order will have zero LOB, which is worse than leaving the bases loaded. Analysts look for a balance where LOB stays low because runners are crossing the plate, not because they never reached base.
- High LOB counts often follow many walks or singles.
- Pitchers with high LOB percentages are considered elite at escaping "jams."
- Consistent LOB issues often lead to coaching changes or lineup shifts.
- Post-season games are frequently decided by which team lowers their LOB.

How to Determine Which LOB Metric Matters for You
Reviewing these criteria helps fans decide if a team's LOB stats signal a temporary slump or a deep tactical flaw.
- Check if LOB occurs mostly with two outs.
- Compare LOB totals against the total runs scored.
- Look at the batting average of the third, fourth, and fifth hitters.
- Evaluate the opponents' pitcher strand rate for that specific game.
Final Thoughts
LOB remains a vital tool for understanding why teams lose despite out-hitting their opponents. Keep an eye on box scores to see which players thrive under pressure.
