Transcript for New York Father Allegedly Stalked Rival Baseball Coach
A new york dad is accused of stalking a rival baseball coach and his son all because of a strikeout. Abc's rob nelson is here. They say there's no crying in baseball, but what about harassing and even stalking? We have another story this morning, proving that perhaps the worst thing about kids' sports is the adults. Reporter: Instead of hearing the crack of a bat, this youth baseball team manager in long island, new york, is stealing the long arm of the law. I didn't do anything? You did nothing wrong? Absolutely not. Reporter: Robert sanfilippo was accused of sending texts to his rival john riordan. Reporter: The two exchanged heated words after riordan's son struck out sanfilippo's son in a game. It started when riordan said he received texts, including photos of riordan's wife in the driveway and his son walking to the bus stop. You saw the pictures, the angle is coming from over here? Yeah, I think he was hiding behind that fence there or that car there. I can't believe I'm on "good morning america" talking about being stalked because of a baseball game, it's crazy. Reporter: On friday, police arrested sanfilippo right in the middle of a game, no less. He's been charged with 20 counts of aggravated harassment and stalking. You can see the decal on the wind here. Riordan says all of this should be a lesson to parents to lighten up and let their kids simply enjoy the game. In the meantime, though, he wants justice. I want to make sure this guy's punished for what he did. I want him to feel the anxiety and the nervousness that me and my family felt. Now, sanfilippo will be back IN COURT OCTOBER 9th. He could face 20 years in prison. He was released without bail over the weekend. What a story. And turning now to another shocking story.
