Boston, MA - 8/28/2012 - Fenway Park - Wendy Bonilla, cq, 11, of East Boston, hurled a baseball into a net to see how fast she could throw. Bonilla will be a sixth grader at the Mario Umana Middle School Academy in East Boston this fall. Fenway Park was host to host hundreds of in-coming Boston 6th graders for the annual “Middle O!” event - a huge back-to-school orientation event featuring free food, information tables, games and a great view of the ballpark.
