The second University baseball team will play an important part in the opening of the new athletic field at Brockton when it meets the High School nine this afternoon at 3.30. Though the opposing teams have played no team in common, the schoolboys are said to have a strong aggregation. In a recent same they pounded out 18 hits, and in consequence Young, who is pitching for the seconds, may have some difficulty in holding the batters in check.
