An intentional walk sends a hitter to first base without throwing pitches, while an earned run charges a pitcher for runs scoring without defensive errors. These two concepts govern how managers manipulate game matchups and how statisticians measure pitching performance.
You'll see intentional walks used when a dangerous slugger steps to the plate with first base open. Instead of giving them something to hit, the manager signals the dugout to award first base automatically. The rule changed in Major League Baseball so pitchers don't have to throw four wide pitches anymore. The manager just signals the umpire, saving time and eliminating the rare wild pitch on an intentional ball four.
The Strategy Behind Intentional Walks
Managers don't issue free passes lightly. Putting a runner on base carries inherent risks, but specific tactical scenarios make the trade-off worthwhile.
You'll often see an intentional walk deployed to set up a double play. If there's a runner on second base with one out, walking the cleanup hitter brings up a weaker batter or a pitcher who is statistically more likely to hit into a ground ball double play.
Another common scenario involves walking a star hitter to load the bases. This creates a force out at every base, allowing the infield to play in or turn an easy double play at home and first. It puts immense pressure on the hitter coming up next, but if that next batter delivers a base hit, the manager takes the blame for manufacturing runs for the opponent.
- Bypassing power: Removing a major home run threat from the batter's box.
- Creating force outs: Loading the bases or setting up plays at any base.
- Right-on-right matchups: Moving past a dangerous left-handed hitter to face a righty reliever.
How Earned Runs Affect Pitching Statistics
While an intentional walk deals with game tactics, an earned run measures a pitcher's actual effectiveness. Official scorers must determine whether a run crossed the plate because of the pitcher's mistakes or because the defense messed up.
A run counts as earned if it scores without the aid of an error or a passed ball. If a pitcher gives up a single, walks the next batter, and allows a home run, every run that scores is earned. The pitcher allowed those baserunners through legal plays, and the hitter drove them home cleanly.
However, if an outfielder drops a routine fly ball that should have been the third out, any runs that score after that dropped catch are unearned. The official scorer assumes the inning should have ended, so subsequent runs don't count against the pitcher's Earned Run Average (ERA).
The Official Scorer's Burden
Determining earned runs isn't always straightforward. Scorers use counterfactual logic to figure out what would have happened without defensive miscues.
If an error happens with two outs, the scorer must track how many pitches it takes to record the actual third out. Every run scoring between the original error and the real third out is classified as unearned. This protects pitchers from being penalized for bad fielding behind them, keeping ERA as a reliable metric of individual pitching skill.

Common Mistakes and Misunderstandings
Fans often confuse how walks and errors interact on the scoreboard. Let's clear up a few persistent misconceptions.
- Walks don't equal unearned runs: Issuing a regular walk or an intentional walk doesn't make a subsequent run unearned. Walks are part of the game's normal flow, so if a runner scores after an intentional walk, that run is earned.
- Passed balls vs. wild pitches: A wild pitch is charged to the pitcher, so runs scoring from it can still be earned. A passed ball is charged to the catcher, making subsequent runs unearned.
- Relief pitcher inheritance: When a reliever enters a game with runners on base left by the previous pitcher, any runs those runners score are charged to the first pitcher, not the reliever.
Frequently Asked Questions
Can an intentional walk lead to an unearned run?
Yes, but only if the runner advances due to a subsequent defensive error or catcher's interference. If they score via standard hits and outs, the run is earned.
Why did Major League Baseball change the intentional walk rule?
MLB instituted the automatic intentional walk in 2017 to speed up the pace of play and eliminate unnecessary, uncompetitive pitches that rarely resulted in surprises.
How does an error in the first inning affect earned runs later?
Errors only impact the specific inning in which they occur. Once a new inning starts, the slate is wiped clean for calculating earned runs, though baserunners carried over from the prior inning retain their status.
Does a catcher's interference call count as an error for earned run purposes?
Catcher's interference is treated similarly to an error by the official scorer. If a runner reaches base via interference and later scores, that run is typically unearned. Check out Baseball Reference for detailed historical tracking of these complex scoring edge cases.
