Many of Adenhart's friends and fans arrived in baseball gear Friday, at the request of the family. Adenhart starred at Williamsport High School before becoming a major leaguer.
The 22-year-old pitcher was killed in a car accident in California on April 9. He was buried Thursday in a private ceremony.
The funeral service was in the school gym. Outside, a large circle containing Adenhart's name and his No. 34 with the Angels was displayed. Inside the gym, a video tribute depicted him at various stages in his life.
