The family of a popular Valley baseball coach says he is alive right now because of a 13-year-old boy.

"If he didn't get CPR he would be gone. He would be dead right now," said Katy Huertta.

Huertta's boyfriend, Isaac Wenrich was doing training drills when he suddenly collapsed.

"He fell flat on his face and then I asked if he was okay and he wasn't answering, so I grabbed his phone and called 911," said 13-year-old Nathan Boyer.

After telling 911 dispatchers what happened, Boyer started doing CPR on his 26-year-old coach.

"I remembered it from the Boy Scouts a couple of years ago. You just lock your hands together and start pushing on their chest," said Boyer.

Chandler firefighters arrived a short time later and rushed Wenrich to the hospital.

Huertta says her boyfriend suffered a massive heart attack.

"He's everything to me. He's my best friend so thank you, thank you, thank you, thank you," Huertta said to Boyer.

Wenrich is still in the hospital, but is expected to make a full recovery.
