Sacrifice FliesSF
SF stands for sacrifice flies in baseball. A fly ball caught for an out that lets a runner tag up and score, with fewer than two outs.
How SF is calculated
Counted. A sacrifice fly is not an at-bat, so it cannot lower a batting average, but it is in the denominator of on-base percentage.
The one way a productive out costs a hitter OBP: OBP = (H + BB + HBP) ÷ (AB + BB + HBP + SF). A bunt that moves a runner (SH) is left out of that denominator entirely.
