AUSTIN -- Mansfield Legacy's Shelbi Vaughan said she wanted to end her Texas Relays career with a bang.
She did more than that.
Vaughan set a national discus record with a throw of 191 feet, 6 inches on Friday at the Clyde Littlefield Texas Relays.
"I was shocked," Vaughan said. "I was expecting it to only be 170 (feet)... I just smiled really big and ran to my coach."

Vaughan edged the previous national record of 190 feet, 3 inches set by Anna Jelmini of Shafter High School (Shafter, Calif.) in 2009. Vaughan also shattered the previous Texas Relays high school girls record of 169 feet, 3 inches set by Michelle Carter of Red Oak in 2002.
The senior broke both records on her second throw. When she let the discus go, Vaughan said she had no idea it was a record-breaker.
"It just felt effortless, easy and smooth," said Vaughan, who earned a spot in the U.S. Olympic Team trials in April.
Vaughan beat the previous Texas Relays record more than once. She also had throws of 180 feet, 1 inch and 181 feet, 6 inches.
"It was pretty exciting, I'm glad because it was consistent," said Vaugham, who will join the Texas A&M track and field team this fall. "Hopefully I'll just keep going up in my throws."
Vaughan said she reached 195 feet last week in practice but wasn't sure if she would match that performance Friday.
"I was a little worried about the wind, though, because it wasn't really working with me. But I guess it did," she said.
Vaughan finished far ahead of the competition. Nekia Jones of Beaumont Ozen took second with a throw of 155 feet, 11 inches. Mansfield Legacy senior Kayla Taylor finished fifth with a throw of 146 feet, 8 inches.
Vaughan said her cell phone was flooded with calls and text messages from friends and family. She'll have a chance to break another national record on Saturday when she competes in the shot put finals.
