The massive tornado that ripped through a handful of Oklahoma City suburbs and killed at least 50 people grabbed the attention of the sports world on Monday, especially the players and coaches with ties to the area.

Kevin Durant, a three-time scoring champion for the NBA’s Oklahoma City Thunder, posted on his Twitter account that he was praying for everyone involved. He added: “Everybody stay safe!”

Mets pitcher Jeremy Hefner went to Plaza Towers Elementary School in Moore, just south of Oklahoma City. The school had its roof torn off and walls knocked down. Some of those killed died at the school.

“I mean, it’s terrifying,” the right-hander said.

Hefner still has family living in Moore. He said he had been in contact with his mother, who told him his cousins and uncles were OK.

“It’s just unfathomable,” he said. “I used to live there.”

Coverage of the tornado damage was on the clubhouse TV as the Red Sox prepared for their game at the Chicago White Sox. “It’s a tragedy when you see a natural disaster like that take place, so many innocent people that are certainly affected, if not directly by injury or possibly loss of life,” Boston manager John Farrell said.

“Having been though something similar back in 1997 that had probably very similar damage, it’s a scary situation. Our thoughts are with all the people affected.”

Farrell played for Oklahoma State in college, and then served as the assistant coach and pitching and recruiting coordinator for the Cowboys for five seasons from 1997-2001. (AP)
