A 16-year-old girl sitting with her parents in seats beyond the third- base line ran onto the field yesterday for a handshake with Derek Jeter. While her father went to the concession stand, the teenager bolted onto the field and jogged toward Jeter. When she neared the shortstop, the girl put out her hand and shook his right hand. Security guards closed in on her and escorted the stunned girl off the field in handcuffs.
