McGowan was tied with two other players for the fifth and final spot to advance to the state tournament at the end of the Region 4-AAA Tournament in Smyrna.
After tying the first sudden death playoff hole, McGowan birdied the next par-three hole after firing a shot to within two feet.
"That was just such a special moment for Amy Beth and all her family that was there," Central coach Kevin Thomas said.

The state tournament will be played in Manchester in a few weeks with tee times yet to be determined.
