Middle Infield Bunt Coverage
Also known as: middle infield bunt rotation
Middle infield bunt coverage is the shortstop and second baseman's job on a bunt. They cover second and third base and back up throws as others field it.
A bunt situation pulls the first baseman, third baseman, and pitcher toward home plate to field the ball. That leaves second and third base uncovered unless the middle infielders rotate to fill the gap. The shortstop usually covers third base if a runner is advancing from second. The second baseman covers first if the first baseman has charged, or covers second if a throw there becomes live. Which base each middle infielder covers depends on where the runners are and which corner infielder has committed to the bunt.
These rotations happen almost at the same moment as the bunt itself. So they have to be drilled as a full team unit rather than left to individual reaction. A shortstop who is late covering third on a bunt-and-run can turn a routine sacrifice into an extra base for the offense. Communication before the pitch confirms who covers what based on the runners on base. That removes hesitation in the split second after the ball is bunted.
Know your covering base before every pitch when a bunt is in order — decide it based on the runners on base, not in the moment the ball is bunted.
Example
With runners on first and second and a bunt in order, the shortstop breaks to cover third base the instant the third baseman charges. At the same time, the second baseman rotates to cover first behind the charging first baseman.
Why it matters
Bunt defense breaks down most often on uncovered bases behind the play, not on the fielding of the bunt itself. Middle infield rotation is what prevents a clean sacrifice from turning into a bigger mistake.
Common mistakes
- Middle infielders freezing to watch the bunt fielded instead of immediately rotating to their covering base
- Confusion over which middle infielder covers which base when both corners crash at the same time
- Failing to pre-communicate rotations based on which bases are occupied before the pitch

Frequently asked questions
Why do middle infielders need to rotate on a bunt?
Because the corner infielders and pitcher move toward home to field the bunt. This leaves second and third base open unless the shortstop and second baseman rotate over to cover them.
