One is breaking the Midland Valley High School discus record.
"The school record is 168 feet," said Riner, whose personal best is 156 feet, 11 inches.
He set that mark on March 22 at the Coaches Classic at Lower Richland High School, where he competed against more than 60 discus throwers.
Riner started participating in track and field while in ninth grade.
"I went to North Augusta, and they told all the linemen (on the football team) to run track," said Riner, who recently signed to play for Newberry College.
When he moved to Midland Valley High, Riner decided to try something different in track and field and took up discus and shot put.
His track and field events have taken him to the state championships for the past two years, and he's hoping to go once again.
Riner said he enjoys track and field, but when making a decision about college his love for football prevailed.
"They don't have a track team," Riner said about Newberry. "I decided I love football more and (that's where) I want to play."
Riner played several positions for Midland Valley, including defensive end and nose guard, and fullback in goal line situations. He will probably play fullback at Newberry, he said.
Midland Valley football coach Rick Knight said he thinks Riner has a bright future. "He earned a scholarship to Newberry to play football, and I feel he'll do really well up there."
Knight described Riner as a hardworking and dedicated athlete.
"He pushes himself," he said.
At Newberry, Riner plans to be a pre-med major so he can pursue a career as a physical therapist. But, he said, he has not ruled out becoming a high school football coach.
