JAIDEN STERN takes off from second base on her way to scoring the winning run in the Pacifica Mariners’ 3-2 extra inning win over Marina Thursday afternoon CIF-SS Division 1 softball action (Orange County Tribune photo).

Valerie Jorgensen singled home Jaiden Stern with the winning run in the bottom of the 11th inning Thursday as Pacifica High opened the CIF-SS Division 1 softball playoffs with a marathon 3-2 win over Marina High on the home diamond.

The Mariners (19-3) will be in action again in the second round Saturday against Vista Murrieta, who defeated Sonora, 4-1.

Marina (11-11) came in as the at-large team from the Surf League against Pacifica, which was the Empire League champs and ranked third in the division, but the Vikings gave the M’s all they could handle, taking a 2-0 lead. The Mariners tied it with two runs in the sixth, and the rest of the game was scoreless until the home team could push across the winning run.

In the 11th, Stern singled to center field, and later stole second. One out later, Jorgensen stroked a line drive to right center to bring Stern home and finish the game.
