Sierra pitcher Lindsey Walljasper put the hammer down when she had to Wednesday. With the Timberwolves clinging to a one-run lead in the fifth inning against visiting Atwater, the Falcons loaded the bases with two outs. Walljasper not only struck out the next batter to end the threat, she struck out the five after that to lead Sierra to a 2-1 non-league win at Sierra High.
