The East Union and Sierra softball teams will sport a new look today when they clash for their final Valley Oak League season contest.

Players will be wearing pink jerseys in observation of breast cancer awareness at Sierra High. Spectators won’t be charged but can offer donations to the American Cancer Society and Manteca Relay for Life.\ Donators will be presented a pink ribbon.

Game time is set for 4:30. The event will double as Senior Day for both teams.

Throwing out first pitches are breast cancer survivors Vickie Mackey, chairperson for the Manteca Relay for Life; Doris Durand, grandmother of Sierra standout pitcher Allison Walljasper; and Julia Owens, grandmother of East Union senior Jillian Goulart and mother-in-law of head coach Brian Goulart.

It is the third high school game this year in which players wore pink.

On Feb. 25, Manteca High’s girls soccer team opened the 2011 season with its Kicking for a Cure festivities. And on Dec. 18 the East Union and Ripon girls basketball teams played in their first Hoops for the Cure Classic.

With already a share of its first VOL championship locked up, Sierra (12-1, 21-1-1 overall) is vying for sole possession today. The Timberwolves were tabbed the No. 1-ranked Division-III team and 19th overall in California by ESPN Rise last week.
