Jenkins, who is from San Marcos, was diagnosed at 38, which is before the recommended age for an initial mammogram. She credits a routine breast exam for diagnosing cancer.
Jenkins participates in the Susan G. Komen 3-day walk, including right after completing chemotherapy. In fact, her team name for the walk each year is called "Save 2nd Base" because she and her family love baseball.
Honorary Bat Girls will take part in pregame activities, be honored during an on-field ceremony and will receive pink MLB merchandise and two tickets to the game. Since the Padres are on the road, Jenkins will be honored on May 18 at Petco Park.
With the assistance of several player judges, MLB selected an Honorary Bat Girl from each of the 30 clubs. Players and on-field personnel will also show their support for breast cancer awareness by sporting pink wristbands -- and in some cases, using pink bats -- on Mother's Day.
